Podcast: Radio Free HPC Runs Down the TOP500

In this podcast, the Radio Free HPC team reviews the new TOP500 list of most powerful supercomputers. “Not much changed in the TOP10 but a lot is changing further down the list. The overwhelming majority of the systems, 478 of them, are based on Intel CPUs. 13 are IBM, and there is 1 system based on Arm provided by Cavium, now part of Marvell.”

Radio Free HPC Looks at the coming wave of 40+ Different AI Chips

In this podcast, the Radio Free HPC Team asks, “What are we going to do with 40+ AI chips?” One such chip, Graphcore, is touted as “the most complex processor” ever at some 20 billion transistors. The VC-backed company out of Bristol, UK is also valued on paper at $1.7b, gaining it the coveted “unicorn” status, apparently the “only western semi-conductor unicorn.”

Radio Free HPC Ponders Amdahl’s Law, GPUs, and the ASC19 Student Cluster Competition

In this podcast, the Radio Free HPC team reviews the results of the ASC19 Student Cluster Competition and HPC workshop in China. “For the first time, a non-mainland-Chinese team wins the top spot. Taiwan takes the gold in part by their stellar performance in HPCG benchmark where they achieved 2 TFlops, some 25% better than the 2nd best team. The system was a 5-node cluster with Infiniband FDR interconnect.”

Radio Free HPC reviews the ASC19 Student Cluster Competition

In this podcast, the Radio Free HPC looks at the recent ASC Student Cluster Competition in Dalien, China. Dan got to witness the finals last week, with 20 teams facing off in a race for HPC performance. “As always, the team, and the rest of humanity, is highly supportive of the student cluster tournaments that take place at SC, ISC, and this Asian one, in addition to many regional supporting events.”

Podcast: Seeing the Black Hole with Big Data

In this podcast, the Radio Free HPC team discusses how the news of the cool visualization of an actual black hole leads to interesting issues in HPC land. “The real point: the daunting 1.75 PB of raw data from each telescope meant a lot of physical drives that had to be flown to the data center. Henry leads a discussion about the race between bandwidth and data size.”

Podcast: Enterprises go HPC at GPU Technology Conference

In this podcast, the Radio Free HPC team looks at news from the GPU Technology Conference. “Dan has been attending GTC since well before it became the big and important conference that it is today. We get a quick update on what was covered: the long keynote, automotive and robotics, the Mellanox acquisition, how a growing fraction of enterprise applications will be AI.”

Podcast: Multicore Scaling Slow Down, and Fooling AI

In this podcast, the Radio Free HPC team has an animated discussion about multicore scaling, how easy it seems to be to mislead AI systems, and some good sized catches of the week. “As CPU performance improvements have slowed down, we’ve seen the semiconductor industry move towards accelerator cards to provide dramatically better results. Nvidia has been a major beneficiary of this shift, but it’s part of the same trend driving research into neural network accelerators, FPGAs, and products like Google’s TPU.”

Podcast: How Real is Ai Anyway?

In this podcast, the Radio Free HPC team discusses AI, bias in AI, and just how real AI actually is. “Ethics in AI, policy, legal framework are all big threads here. The trigger is the rather funny article from The Register: Artificial Intelligence, You Know it isn’t real, yeah?”

Radio Free HPC Looks at NVIDIA’s acquisition of Mellanox

In this podcast, the Radio Free HPC team looks at NVIDIA’s acquisition of Mellanox. “This called for an emergency session of our crack panel. While it will be several months before the full impact of this merger is felt, the RFHPC team believes this will change both the HPC and the Datacenter markets. It also signals Nvidia’s journey towards becoming more of a systems company and gives them a better shot at the enterprise AI market.”

Podcast: The sinking of the Itanic, a respectful farewell

In this podcast, the Radio Free HPC says goodbye to Intel’s Itanium processor. “After years of futility, Intel has finally put a stake in the heart of their Itanium processor. The final shipment will take place in 2021. The boys discuss some Itanium history and reasons behind the end of the processor.”
