Could RISC-V become a force in HPC? We talk to the experts • The Register

Analysis The RISC-V architecture looks set to become more prevalent in the high performance computing (HPC) sector, and could even become the dominant architecture, at least according to some technical experts in the field.

Meanwhile, the European High Performance Computing Joint Undertaking (EuroHPC JU) has just announced a project aimed at the development of HPC hardware and software based on RISC-V, with plans to deploy future exascale and post-exascale supercomputers based on this technology.

RISC-V has been around for at least a decade as an open source instruction set architecture (ISA), while actual silicon implementations of the ISA have been coming to market over the past several years.

Among the attractions of this approach are that the architecture is not only free to use, but can also be extended, meaning that application-specific functions can be added to a RISC-V CPU design, and accessed by adding custom instructions to the standard RISC-V set.

This latter could prove to be a driving factor for broader adoption of RISC-V in the HPC sector, according to Aaron Potler, Distinguished Engineer at Dell Technologies.

“There’s synergy and growing strength in the RISC-V community in HPC,” Potler said, “and so RISC-V really does have a very, very good chance to become more prevalent on HPC.”

Potler was speaking in a Dell HPC Community online event, outlining perspectives from Dell’s Office of the Chief Technology and Innovation Officer.

However, he conceded that to date, RISC-V has not really made much of a mark in the HPC sector, largely because it wasn’t initially designed with that purpose in mind, but that there is “some targeting now to HPC” because of the business model it represents.

He made a comparison of sorts with Linux, which like RISC-V, started off as a small project, but which grew and grew in popularity because of its open nature (it was also free to download and run, as Potler acknowledged).

“Nobody would have thought then that Linux would run on some high end computer. When in 1993, the TOP500 list came out, there was only one Linux system on it. Nowadays, all the systems on the TOP500 list run Linux. Every single one of them. It’s been that way for a few years now,” he said.

If Linux wasn’t initially targeting the HPC market, but was adopted for it because of its inherent advantages, perhaps the same could happen with RISC-V, if there are enough advantages, such as it being an open standard.

“If that’s what the industry wants, then the community is going to make it work, it’s gonna make it happen,” Potler said.

He also made a comparison with the Arm architecture, which eventually propelled Fujitsu’s Fugaku supercomputer to the number one slot in the TOP500 rankings, and which notably accomplished this by extending the instruction set to support the 512bit Scalable Vector Engine units in the A64FX processor.

“So why wouldn’t a RISC-V-based system be number one on the TOP500 someday?” he asked.

There has already been work done on RISC-V instructions and architecture extensions relating to HPC, Potler claimed, especially those for vector processing and floating point operations.

All of this means that RISC-V has potential, but could it really make headway in the HPC sector, which once boasted systems with a variety of processor architectures but is now dominated almost entirely by X86 and Arm?

“RISC-V does have the potential to become the architecture of choice for the HPC market,” said Omdia chief analyst Roy Illsley. “I think Intel is losing its control of the overall market and the HPC segment is becoming more specialized.”

Illsley pointed out that RISC-V’s open-source nature means that any chipmaker can produce RISC-V-based designs without paying royalties or licensing fees, and that is supported by many silicon makers as well as by open-source operating systems.

Manoj Sukumaran, Principal Analyst for Datacenter Compute & Networking at Omdia agreed, saying that the biggest advantage for RISC-V is that its non-proprietary architecture lines up well with the technology sovereignty goals of various countries. “HPC Capacity is a strategic advantage to any country and it is an inevitable part of a country’s scientific and economic progress. No country wants to be in a situation like China or Russia and this is fueling RISC-V adoption,” he claimed.

RISC-V is also a “very efficient and compelling instruction set architecture” and the provision to customize it for specific computing needs with additional instructions makes it agile as well, according to Sukumaran.

The drive for sovereignty, or at least greater self-reliance, could be one motive behind the call from the EuroHPC JU for a partnership framework to develop HPC hardware and software based on RISC-V as part of EU-wide ecosystem.

This is expected to be followed up by an ambitious plan of action for building and deploying exascale and post-exascale supercomputers based on this technology, according to the EuroHPC JU.

It stated in its announcement that the European Chips Act identified RISC-V as one of the next-generation technologies where investment should be directed in order to preserve and strengthen EU leadership in research and innovation. This will also reinforce the EU’s capacity for the design, manufacturing and packaging of advanced chips, and the ability to turn them into manufactured products.

High-performance RISC-V designs already exist from chip companies such as SiFive and Ventana, but these are typically either designs that a customer can take and have manufactured by a foundry company such as TSMC, or available as a chiplet that can be combined with others to build a custom system-on-chip (SoC) package, which is Ventana’s approach.

Creating a CPU design with custom instructions to accelerate specific functions would likely be beyond the resources of most HPC sites, but perhaps not a large user group or forum. However, a chiplet approach could de-risk the project somewhat, according to IDC Senior Research Director for Europe, Andrew Buss.

“Rather than trying to do a single massive CPU, you can assemble a SoC from chiplets, getting your CPU cores from somewhere and an I/O hub and other functions from elsewhere,” he said, although he added that this requires standardized interfaces to link the chiplets together.

But while RISC-V has potential, the software ecosystem is more important, according to Buss. “It doesn’t matter what the underlying microarchitecture is, so long as there is a sufficient software ecosystem of applications and tools to support it,” he said.

Potler agreed with this point, saying that “One of the most critical parts for HPC success is the software ecosystem. Because we’ve all worked on architectures where the software came in second, and it was a very frustrating time, right?”

Developer tools, especially compilers, need to be “solid, they need to scale, and they need to understand the ISA very well to generate good code,” he said.

This also plays a part in defining custom instructions, as these calls for a profiler or some performance analysis tools to identify time consuming sequences of code in the applications in use and gauge whether specialized instructions could accelerate these.

“So if I take these instructions out, I need a simulator that can simulate this [new] instruction. If I put it in here and take the other instructions out, the first question is, are the answers correct? Then the other thing would be: does it run enough to make it worthwhile?”

Another important factor is whether the compiler could recognize the sequences of code in the application and replace it with the custom instruction to boost performance, Potler said.

“You also see that extensions to the instruction set architecture will provide performance benefits to current and future HPC applications, whatever they may be,” he added.

However, Buss warned that even if there is a great deal of interest in RISC-V, it will take time to get there for users at HPC sites.

“There’s nothing stopping RISC-V, but it takes time to develop the performance and power to the required level,” he said, pointing out that it took the Arm architecture over a decade to get to the point where it could be competitive in this space.

There was also the setback of Intel pulling its support for the RISC-V architecture last month, after earlier becoming a premier member of RISC-V International, the governing body for the standard, and pledging to offer validation services for RISC-V IP cores optimized for manufacturing in Intel fabs.®

How Entrepreneurial Mindset Is Necessary For Startup Triumph

Entrepreneurial Mindset & Startup Triumph

The Voice Of EU | In today’s dynamic world of startups, achieving exceptional growth isn’t a one-shot endeavor. It demands more than a stroke of luck or a hidden formula; it requires an unwavering entrepreneurial mindset, a steadfast commitment, and consistent, sustained effort.

How Entrepreneurial Mindset Is Necessary For Startup Triumph

Picture Credits: PS Vault

In the subsequent sections, I’ll dissect five crucial factors to high-performance growth psychology that can steer your startup towards unprecedented success.

1. The Primacy of Communication

In the quest for growth, it’s commonplace for companies to prioritize feature development over precise language. Yet, this approach is fundamentally misguided. Language should precede all else.

The words you choose to articulate your product and company not only define your identity but also establish user expectations. Your choice of language wields significant influence, shaping how users perceive and engage with your offering. For example, a ridesharing service becomes exponentially more appealing when it promises a ride in four minutes or less.

User-Centric Empathy

Successful Founders distinguish themselves by their ability to think beyond their product and focus on the users. It’s imperative to understand how users think and feel, considering the intricate web of their lives.

To truly stand out, you must ask, “What does my product mean to them, and how does it fit into their world?” Behind every thriving tech company lies a profound insight into human psychology, a key that resonates with users’ needs and desires.

Perpetual Motion

In a landscape dominated by industry giants, speed emerges as your greatest ally. Much like the ancient shrew that thrived through ceaseless motion, startups must embrace a similar philosophy, “be creative, be dynamic.”.

To navigate the whirlwind of rapid changes and outmaneuver larger competitors, you must be in perpetual motion. Swift experimentation, rapid iteration, and an unwavering forward momentum are the cornerstones of sustained growth.

The Embrace of Data

Commitment to measurement is the engine driving growth. Being truly data-driven is not merely a buzzword, but a fundamental philosophy. Devoting substantial engineering resources to measurement, up to half of your total, demonstrates a genuine love for data. It should be an integral part of your company culture, displayed prominently for all to see. Your daily stats should be a source of pride and a testament to your dedication to growth.

Resilience in the Face of Setbacks

Failure is a constant companion on the path to growth. Embracing a mindset that can endure these setbacks is crucial. Most initiatives will yield negative outcomes, and being able to move forward despite this is paramount.

It’s a psychology of resilience, encapsulated in the saying, ‘Success is going from failure to failure with no loss of enthusiasm‘. This grit and determination are the keys to achieving substantial growth.

Implementing Growth Psychology

To instill these growth-oriented mindsets in your team, consider the following steps:

1. Teach the mentality, particularly the willingness to endure repeated small failures.

2. Clarify that every member is directly responsible for growth, regardless of their official role.

3. Provide your team with the authority to drive product changes and allocate resources for growth.

4. Encourage your team to be more aggressive in pushing growth boundaries.

5. Keep taking big swings and be open to creative, high-risk strategies.

Ultimately, growth is a collective effort, but it hinges on the psychology of the CEO. Founders shape their startups through consistent actions and decisions.

Cultivating the right growth psychology can be the difference between sluggish progress and exponential success. It empowers your company with data-driven visibility, constant momentum, and the audacity to aim for 1000% growth.

4 Ways AI Is Transforming Social Media Marketing

Rebecca Barnatt-Smith explains how marketers and content creators can use AI-powered predicative analytics, content personalisation and scheduling tools to create successful social media campaigns.

Is artificial intelligence (AI) the next big thing for social media marketers?

With over 4.26bn social media users to serve, AI is set to transform targeting and improve content personalisation for a more focused marketing future.

AI is not a new phenomenon in the marketing world. When surveyed, over 56pc of chief marketing officers (CMOs) said they use automated assistants for content personalisation and tracking consumer insights. AI-driven social strategies are just the next step in a fast-approaching digital future of campaigning.

However, could a push for AI-infused social campaigns pose ethical concerns for future marketers? From breaching consumer privacy to decision system bias, with great technology comes great responsibility.

Here we look at AI’s impact on social media marketing and discuss some of the best AI-infused platforms that are tipped to lead social strategies in 2023.

How can AI improve your social media?

Using AI, you can quickly segment large demographics into targeted groups, track viral trends and schedule personalised content responses in seconds.

If you want to compete against commerce giants and industry leaders, your social content should be consistent, compelling and customised to each and every consumer. Here are some insights into how AI can help.

Content personalisation

In 2023, 73pc of shoppers expect brands to offer them a personalised experience and content that speaks directly to their values. AI can enhance a brand’s personalisation potential in a number of ways.

Automatically harvesting behavioural and historical consumer data, AI-generated platforms can quickly learn about a user’s interests and predict what products or services they’d be most likely to interact with, resulting in a hyper-individualised experience that can boost engagement and increase the chances of conversion.

However, with 69pc of consumers now concerned about how their data is collected and used on mobile apps, it’s important to use content personalisation tools with caution.

“As consumers continue to learn and become more informed about their data rights and how their data is currently used, I expect we’ll see more and more calls from consumers to have their data protected,” claims Swish Goswami, CEO of browser extension platform Surf.

The key here is to keep your consumers in the loop. Give your followers a chance to choose what they share, and make sure the data you collect is transparent. Personalised ads, posts and targeting is a business game changer, as long as you have consent.

Automated content posting

Creating content for your brand is the driving force behind audience engagement.

While experts recommend that brands upload social media content daily, this process can be time-consuming. Using AI-driven social media tools, marketers can feel the pressure drain away, as automated assistants not only create original content formats but automatically schedule them too.

For example, AI-infused content planner Sprout Social can generate personalised tweets that reply to fans and followers in seconds. Instead of physically manning social channels and checking for replies, Sprout Social monitors a brand’s comment section before analysing the tone and sentiment of a reply. Sprout can then suggest an auto-response that aims to carry on the conversation between the brand and the consumer.

While automatic replies can pose ethical questions about a brand’s true identity, Sprout Social ensures that before an automatic reply is posted, the social media manager is able to review and edit the content. This guarantees that the brand’s voice still has a human tone when connecting with its audience.

Hubspot is also a nifty tool to have under your belt, especially if you’re struggling to develop new content ideas. By simply pasting a content link into Hubspot’s content generation feature, it uses AI to quickly analyse the metadata and create an original social post.

Social media advertising

Social platforms are the perfect vessels for advertising success. Whether you choose TikTok or Instagram, with the ability to post a pop-up on a user’s scroll-down feed, or a sponsored TikTok that blends seamlessly into a For You Page, social channels allow for a more organic future of ad placement.

However, with so many brands utilising social media, it can be hard to make your ad stand out from the crowd. Your ads must be full of compelling captions, quick links to your online store and contain a personalised hook for your target consumer.

Using AI, brands can optimise their ad performance on social channels. With the ability to analyse historic campaigns and current trends among industry leaders, AI-driven ad tools such as Sprinklr can make recommendations for smarter campaigns that drive better results.

Also, AI-infused ad strategies are more likely to be personalised to each user’s feed. AI tools like Phrase can generate customisable ad phrasing that adapts to target individual customers. This is a great way to ensure your ad captions remain fluid and speak directly to a diverse set of leads.

Predictive analytics

While it’s easier than ever to track social media performance, acting on your results can be tricky. AI-generated monitoring tools utilise the data harvested on content engagement, clicks and consumers, and turn these insights into predictions for new campaigns, content formats and new target groups to work on.

The key here is to take these predictions and turn them into content campaigns that frame the values of your brand. It’s also important to do your own research before jumping into an AI-generated content campaign, as just like humans, AI can have a decision system bias.

“AI is fallible and in a perfect world should be used critically, responsibly and democratically,” says Annie Brown, founder of the creative sharing platform Lips. “AI is only as fair and accurate as the algorithm, and the algorithm is only as fair or accurate as the human-generated information it gathers.”

For example, if the only data your AI tool collects is from a specific consumer group, it’s likely to inherit the same biases. Therefore, it’s important to perform your own content research if you want your brand voice to remain objective on social media.

However, with more data to inform their strategy, brands that use AI to influence their social campaigns are more likely to see higher conversion payoffs.

As social platforms continue to become more visual, AI can also enhance video and image analysis. For example, AI algorithms can now identify certain aspects of Instagram images and TikTok videos, making it easier to gather more data on a user’s interests and behaviours.

Visual analytics could help a brand improve its content styles as AI tools learn more about audience preferences and the formats going viral.

Could AI take social media marketing to the next level?

AI can enhance the experience a consumer has with a brand on social media. With predictive analytics at play, the content targeted users receive is more likely to speak directly to their values.

While there are still ethical concerns surrounding an AI-infused future of campaigning, there’s hope on the horizon for data-sharing transparency and the impact of algorithmic biases as both consumers and marketers take control of how data is gathered and shared.

As machine learning gets even smarter, the possibilities are endless for brands that want to get close to their leads. From automated responses to automatic content creation, the future of social media marketing is AI-driven.

A New Era of Flight: Alef Aeronautics’ Flying Car Receives FAA Certification

Alef Aeronautics’ Flying Car Receives FAA Certification

By RAZA H. QADRI (ALI)

In a world where futuristic visions of flying cars have long captured our imaginations, a new era of flight is about to take off. On June 12, 2023, the Federal Aviation Administration (FAA) issued a Special Airworthiness Certificate to Alef Aeronautics, granting their flying car model the official approval to take to the skies.

This marks a pivotal moment in the history of advanced air mobility (AAM) and represents a significant step towards revolutionizing transportation as we know it.

The Concept and Creation of Model A

Alef Aeronautics, a California-based company, began working on the concept of their flying car in 2015, driven by a vision of safe and efficient urban air mobility. The result of their innovative efforts is the Model A, a road-legal passenger car designed to accommodate two occupants. The Model A boasts an impressive driving range of 200 miles (322 km) and a flight range of 110 miles (177 km), making it a viable option for short-to-medium distance travel.

The sleek and compact design of the Model A is intended to resemble a regular car, ensuring that it can seamlessly blend into everyday life. One of the standout features of this futuristic vehicle is its ability to achieve vertical take-off and transform into a biplane midflight. The doors of the Model A serve a dual purpose, cleverly converting into wings that allow for a smooth transition from ground to air. This innovative design not only promises a thrilling flying experience but also aims to dramatically change the way we commute.

Technological Challenges and Safety Concerns

While the Model A holds great promise for the future of transportation, numerous technological challenges remain to be overcome. Jim Dukhovny, the Chief Executive of Alef Aeronautics, acknowledges that some components required for the flying car’s design do not currently exist in the world. The development of highly specialized propeller motor systems is crucial to avoid differential stress and ensure the safety and stability of the flying car. Balancing size, weight, and price constraints presents further hurdles in making these vehicles accessible to the public while maintaining their safety standards.

‘Future of Air Mobility’ by PS Art — ‘THE VOICE OF EU’

Despite these challenges, the Model A is poised to undergo manufacturing in 2025 or early 2026, with vehicles already available for pre-order. The current price tag stands at $300,000 (£246,000), but Alef Aeronautics aims to scale down the cost to $35,000 or £28,700 per vehicle in the future. However, ensuring a seamless transition from ground to air remains a complex issue that needs to be addressed to guarantee passenger safety during take-off and landing.

Regulation and Infrastructure

As the concept of flying cars inches closer to reality, the focus shifts towards ensuring a smooth integration of this new mode of transportation into urban landscapes. Urban air mobility operations will primarily be overseen by a country’s air navigation service provider (ANSP), such as the FAA in the United States. The ANSP holds full jurisdiction over the nation’s airspace operations and is responsible for certifying new aircraft types after rigorous safety reviews.

According to a blueprint report published by the FAA, the initial implementation of flying car operations will leverage existing regulatory frameworks and rules, such as visual flight rules and instrument flight rules, as a basis for enhanced aircraft performance and higher levels of autonomy. However, several concerns need to be addressed, including noise, pollution, security, sustainability, and cost. The issue of who will drive these flying cars and whether passengers will need a license also requires careful consideration.

Trajectory Planning and Noise Pollution

One of the significant concerns surrounding the advent of flying cars is the potential for collisions and noise pollution. With these vehicles traveling at high speeds, ensuring precise path and trajectory planning becomes essential to avoid accidents. However, to date, there are no provisions for flying car trajectory route planning, necessitating robust research and technology development to address this challenge.

Moreover, designing flying cars to be exceptionally quiet presents another obstacle, particularly when large-scale commercial operations could involve hundreds of take-offs and landings every hour. Electric propellers and other propulsion design elements can mitigate noise pollution, but strict government regulations may be necessary to control noise levels effectively. Drawing on metrics from traditional airplanes and helicopters, guidelines for air infrastructure can be adapted to curb noise pollution.

Equitable Access and the Future of Flying Cars

As the reality of flying cars draws nearer, ensuring equitable access to this mode of transportation becomes paramount. Initially, air taxis may primarily serve densely populated areas, offering a convenient and efficient solution for peak commute times in cities like central London or New York City. However, cost considerations may limit access, making these services accessible mainly to affluent travelers.

Addressing this concern, the Los Angeles Department of Transportation (LADOT) collaborated with Arup, a British firm specializing in design, engineering, and sustainability services, to develop a report on urban air mobility policy framework considerations. Emphasizing the importance of treating flying cars as a funded municipal service and a public good, this report suggests that once the proof of concept is established, rigorous testing has taken place, and safety risks are mitigated, advanced air mobility services should function as a community-wide asset, similar to libraries, schools , airports, or roads.

By viewing urban air mobility as an essential public service, cities can play a crucial role in establishing rules and regulations to ensure safe and equitable access to flying car services.

Los Angeles, A Potentially Early Adopter

With its legendary traffic congestion, Los Angeles has emerged as a city with significant potential for embracing flying cars as a solution to its transportation woes. The promise of faster, traffic-free commutes is undoubtedly enticing for Angelenos. However, it is essential to manage expectations, as urban air mobility will not entirely eliminate congestion. Instead, the focus should be on utilizing air taxis strategically in densely populated areas during peak hours to optimize their impact.

NASA and FAA’s Partnership

As the world gears up for the new era of flight, significant progress is being made through collaborative efforts. NASA, along with the FAA, university researchers, and industry leaders, has joined forces to develop software tools that model and predict AAM noise. This initiative aims to assist manufacturers in designing quieter vehicles to minimize noise pollution in urban environments. By exploring human response to low-level noise and understanding the threshold for “broadband noise,” NASA seeks to predict the combined sound generated by multiple flying cars in flight simultaneously.

The Road Ahead

The journey towards incorporating flying cars into our daily lives remains a complex and multifaceted process. Addressing technological challenges, ensuring safety during transitions from ground to air, and managing noise pollution are just some of the hurdles that must be overcome. Regulatory bodies and urban planners will play a pivotal role in defining the future of urban air mobility, establishing guidelines for air infrastructure, and implementing necessary rules to guarantee a safe and seamless experience for all.

While flying cars are often seen as the epitome of futuristic innovation, it is crucial to ground these advancements in practicality and feasibility. Economies of scale will likely play a significant role in making flying cars more affordable over time, eventually broadening their accessibility beyond the wealthiest travelers. As with any transformative technology, public acceptance and engagement will be essential to ensure the integration of flying cars as a valuable addition to our transportation ecosystem.

As the Model A prepares to take its maiden flight, it represents not only a significant milestone for Alef Aeronautics but also for the entire field of advanced air mobility. The dream of a future where flying cars dot the skies may soon be closer than ever before, bringing a new era of transportation and endless possibilities.

In conclusion, the FAA’s certification of Alef Aeronautics’ flying car marks a crucial turning point in the history of air mobility. While significant challenges and complexities lie ahead, the progress made by companies like Alef Aeronautics, along with the collaboration of regulatory bodies and industry leaders, pave the way for a future where flying cars become a reality in our cities. As we embrace this new era of flight, it is essential to strike a balance between innovation, safety, and sustainability, ensuring that the promises of flying cars are fully realized and integrated into our lives in a way that benefits all members of society. The skies of tomorrow hold the potential to unlock a new dimension of transportation, ushering in a world where flying cars soar alongside traditional vehicles, revolutionizing the way we move and connect. The journey has just begun, and with each step forward, we inch closer to a future that once seemed only possible in our wildest dreams.
