In this feature article from our friends over at Mellanox, we discuss how weather and climate models are both compute and data intensive. Forecast quality scales with modeling complexity and resolution. Resolution depends on the performance of supercomputers. And supercomputer performance depends on the underlying interconnect technology: to get higher performance, the interconnect must be able to move data quickly, effectively and in a scalable manner across compute resources.

Lenovo to deploy 17 Petaflop supercomputer at KIT in Germany https://insidehpc.com/2020/05/lenovo-to-deploy-17-petaflop-supercomputer-at-kit-in-germany/ Fri, 15 May 2020 07:17:11 +0000 https://insidehpc.com/?p=84251

Today Lenovo announced a contract for a 17 petaflop supercomputer at Karlsruhe Institute of Technology (KIT) in Germany. Called HoreKa, the system will come online this Fall and will be handed over to the scientific communities by summer 2021. The procurement contract is reportedly on the order of EUR 15 million. "The result is an innovative hybrid system with almost 60.000 next-generation Intel Xeon Scalable Processor cores and 220 terabytes of main memory as well as 740 NVIDIA A100 Tensor Core GPUs. A non-blocking NVIDIA Mellanox InfiniBand HDR network with 200 GBit/s per port is used for communication between the nodes. Two Spectrum Scale parallel file systems offer a total storage capacity of more than 15 petabytes."

SDSC Expanse Supercomputer from Dell Technologies to serve 50,000 Users https://insidehpc.com/2020/04/sdsc-expanse-supercomputer-from-dell-technologies-to-serve-50000-users/ Fri, 10 Apr 2020 14:54:32 +0000 https://insidehpc.com/?p=83634

In this special guest feature, Janet Morss at Dell Technologies writes that the company will soon deploy a new flagship supercomputer at SDSC. "Expanse will deliver the power of 728 dual-socket Dell EMC PowerEdge C6525 servers with 2nd Gen AMD EPYC processors connected with Mellanox HDR InfiniBand. The system will have 93,000 compute cores and is projected to have a peak speed of 5 petaflops. That will almost double the performance of SDSC’s current Comet supercomputer, also from Dell Technologies."

GPCNeT or GPCNoT? https://insidehpc.com/2020/03/gpcnet-or-gpcnot/ https://insidehpc.com/2020/03/gpcnet-or-gpcnot/#comments Mon, 02 Mar 2020 18:00:00 +0000 https://insidehpc.com/?p=82954

In this special guest feature, Gilad Shainer from Mellanox Technologies writes that the new GPCNeT benchmark is actually a measure of relative performance under load rather than a measure of absolute performance. "When it comes to evaluating high-performance computing systems or interconnects, there are much better benchmarks available for use. Moreover, the ability to benchmark real workloads is obviously a better approach for determining system or interconnect performance and capabilities. The drawbacks of GPCNeT benchmarks can be much more than its benefits."
