Little-known Japanese CPU threatens to make Nvidia, Intel and AMD obsolete in HPC market

Sandia National Laboratories has announced it will be the first Department of Energy labs in the US to deploy the Fujitsu A64FX, the only ARM-based processor designed from ground up for HPC projects and supercomputers.

Fujitsu is known primarily for its business laptops, tablets and desktops, but is a behemoth in its own right when it comes to processors, having been in the business for well over half a century.

Launched in 2019, the CPU has 48 cores, a theoretical peak performance of 3.38 TFLOPS, runs at 2.2GHz and has 32GB HBM2 memory on the die itself.

What makes it ideal for the HPC market is that it provides far higher bandwidth performance between memory and the CPU - up to 1TBps. Moving data to and from the CPU is the biggest obstacle by far to what researchers refer to as exascale computing.

What makes the A64FX even more exciting is that Fujitsu wants the technology to trickle down to hyperscalers and major cloud computing giants so that the masses can benefit too.

Given it is based on ARM architecture, it can (and has) run Linux distributions out of the box and even Microsoft Windows.

It is considered a general purpose CPU, but surpasses even GPUs from Nvidia and AMD on the all-important metric of performance per watt. Indeed, a 768-CPU prototype sits on top of the Green500 list - the leaderboard for supercomputers that deliver the most power per watt.

The A64FX was designed expressly to power the successor of Japan’s main supercomputer, the K, which was decommissioned back in August 2019. 

Its replacement - the Fugaku - is expected to be 100 times faster when it launches later this year, will run on a Linux distribution called McKernel and will reach a staggering 400 petaflops. The aim is for it to be the first supercomputer to hit one exaflop when fully deployed with half a million processors buzzing.

The future of Magic Leap's promising AR efforts dim after layoffs

The Magic Leap Two is now further away than ever, unfortunately. Today in a blog post the augmented reality pioneer announced major layoffs and has decided to cut up to half of its workforce, according to some reports. The original Magic Leap One was supposed to be one of the first mainstream augmented reality headsets when it launched in 2018, but a high price point and lack of interest from developers left the headset high and dry after launch. According to the blog post, Magic Leap says it will be focusing its efforts on enterprise solutions (a statement HTC has made recently as well) and shift its focus away from consumer technology… at least for the time being.  The company has been open about creating a second headset that would offer improved specs for some time, but how that work will now have to go forward without half of the team , according to some estimates, remains to be seen. Is the window closing on augmented reality?  Although it’s just one company, Magic...

Airship acquires SMS commerce company ReplyBuy

Airship is announcing that it has acquired mobile commerce startup ReplyBuy . The startup (which was a finalist at TechCrunch’s 1st and Future competition in 2016) works with customers like entertainment venues and professional and college sports teams to send messages and sell tickets to fans via SMS. It raised $4 million in funding from Sand Hill Angels, Kosinski Ventures, SEAG Ventures, Enspire Capital, MRTNZ Ventures and others, according to Crunchbase . Airship, meanwhile, has been expanding its platform beyond push notifications to cover customer communication across SMS, email, mobile wallets and more. But CEO Brett Caine said this is the first time the company is moving into commerce. While sports and concerts tickets might not be a booming market right now, Caine suggested that the company is actually seeing increased purchasing activity “in and around the Airship platform” as businesses try to drive more in-app purchases. He also suggested that both the COVID-19 pandem...
