Intel MPI Library Improves Google Cloud HPC

Google Cloud provides a variety of virtual machine (VM) families, such as H3 compute optimised VMs, which are perfect for HPC applications

Virtual machines (VMs) optimised by Intel software tools integrate the latest computing, networking, and storage advances on a single platform

MPICH project, this commercial-grade MPI implementation handles fabric-specific communication aspects via the OpenFabrics Interface

PSM3 provider is enhanced in version 2021.11 of the Intel MPI Library, which also offers tunings for the PSM3 and OFI/TCP providers for the Google Cloud

Intel MPI Library 2021.11 takes advantage of 4th-generation Intel Xeon Scalable Processors' large core counts and advanced functionality

When combined, these enhancements provide third-generation virtual machines with Titanium access to new performance and application features

Through parallel computing, programs such as Siemens Simcenter STAR-CCM+ software reduce the time-to-solution

Google and Intel tested Simcenter STAR-CCM+ on H3 instances to demonstrate the new Intel MPI Library's performance advantages

Intel MPI 2021.7 and its TCP provider, as well as Intel MPI 2021.11 and the PSM3 libfabric provider, were used to execute the benchmarks

On CentOS Linux release 7.9.2009-powered Google  Cloud H3 instances, with 88 MPI processes per node and 200 Gbps networking, Simcenter STAR-CCM+ version 2306 (18.06.006) was evaluated

The Intel MPI Library is available in the Google Cloud HPC VM Image at the most recent version
