A Closer Look at the New Power9, Titan V, and Snapdragon 845

In this podcast, the Radio Free HPC team looks at all new fast devices that came to market this week for HPC.

IBM Power9 Servers are here! Launched this week, the AC922 POWER9 servers will form the basis of the world’s fastest “Coral” supercomputers coming to ORNL and LLNL. Built specifically for compute-intensive AI workloads, the new POWER9 systems are capable of improving the training times of deep learning frameworks by nearly 4x allowing enterprises to build more accurate AI applications, faster.

NVIDIA Titan V brings Volta to the Desktop. Not to be outdone, NVIDIA introduced their new high end TITAN V GPU for desktop PCs. Powered by the Volta architecture, TITAN V excels at computational processing for scientific simulation. Its 21.1 billion transistors deliver 110 teraflops of raw horsepower, 9x that of its predecessor, and extreme energy efficiency.

Snapdragon 845 chip based on the ARM architecture brings AI inference to your smartphone. With A75 CPU cores clocking as high as 2.8 GHz, the new architecture also enables it to maintain the same level of performance with a 30% power reduction.

After that, we do our Catch of the Week.

A Controversy in the Irish Supercomputing List

In this podcast, the Radio Free HPC team looks at a controversy stirred up by the recent Irish Supercomputing List.
The 9th Irish Supercomputer List was released this week. For the first time, Ireland has four computers ranked on the Top500 and Ireland is now ranked number one globally in terms of number of TOP500 supercomputers per capita.

Controversy: Since the publication of the List, a third party called the Irish Centre for High-End Computing (ICHEC) has expressed concerns that the press release issued by the Irish Supercomputing List is misleading. You can read their opinion here.
After that, we do our Catch of the Week.

A Recap of SC17 in Denver

In this podcast, the Radio Free HPC team describes the highlights of SC17 in Denver. Highlights includes the debut of ARM hardware for HPC, a Rasberry Pie Cluster, and pervasive liquid cooling.

Other highlights include:
  • Posit Research was there at the Innovation Showcase with an all-new company working to proliferate Unum based computing invented by John Gustafson from A*STAR in Singapore.
  • New high performance interconnects are proliferating with PCIe technologies, Gen-Z, etc.
  • The Student Cluster LINPACK record was smashed this year with 51.8 Teraflops. Nanyang University achieved this record number with the new NVIDIA Tesla V100 GPUs.
After that, we do our catch of the week.

Radio Free HPC Reviews the Latest TOP500 List

In this podcast, the Radio Free HPC team reviews the latest TOP500 list in front of a live audience in Denver at SC17.

The fiftieth TOP500 list of the fastest supercomputers in the world has China overtaking the US in the total number of ranked systems by a margin of 202 to 144. It is the largest number of supercomputers China has ever claimed on the TOP500 ranking, with the US presence shrinking to its lowest level since the list’s inception 25 years ago.

Just six months ago, the US led with 169 systems, with China coming in at 160. Despite the reversal of fortunes, the 144 systems claimed by the US gives them a solid second place finish, with Japan in third place with 35, followed by Germany with 20, France with 18, and the UK with 15.

China has also overtaken the US in aggregate performance as well. The Asian superpower now claims 35.3 percent of the TOP500 flops, with the US in second place with 29.8 percent.

The top 10 systems remain largely unchanged since the June 2017 list, with a couple of notable exceptions.

Sunway TaihuLight, a system developed by China’s National Research Center of Parallel Computer Engineering & Technology (NRCPC), and installed at the National Supercomputing Center in Wuxi, maintains its number one ranking for the fourth time, with a High Performance Linpack (HPL) mark of 93.01 petaflops.

A Preview of the SC17 Student Cluster Competiton

In this podcast, the Radio Free HPC team previews the SC17 Student Cluster Competition.

"In this real-time, non-stop, 48-hour challenge, teams of undergraduate and/or high school students assemble a small cluster on the exhibit floor and race to complete a real-world workload across a series of applications and impress HPC industry judges." 

Dan's got the inside scoop on all the new wrinkles of the competition this year, where 16 international student teams will go head-to-head. There's an all high school squad from Indiana, returning champs from China, and an all-new cloud computing component utilizing Cycle Computing on Azure.

After that, we do our Catch of the Week.
