A good source for high-performance computing information is the HPC Advisory Council (www.hpcadvisorycouncil.com). Of course one can find many news sites - insideHPC, HPCWire and others, but the HPC Council is a good option if you want to get more in the details, to learn on new technologies and solutions being developed etc. One of the recent publications was a case study on STAR-CCM+ application (CFD) - http://www.hpcadvisorycouncil.com/pdf/STAR-CCM_Analysis_Intel_E5_2680_V2.pdf.
The publication included for the first time some performance information on a new MPI solution – called HPC-X. In the world of high-performance computing, MPI is one of the most used parallel communications library. There are some open source solutions, such as MPICH, MVAPICH, OpenMPI and commercial options – Platform MPI (formally known as HP MPI, now owned by IBM) and Intel MPI. HPC-X is a new solution from Mellanox which seems to be based on Open MPI plus various accelerations. In the past I did cover new releases of both MVAPICH and OpenMPI as these are the two most used solutions by us so far.
The combination of open source base and support does make HPC-X an very interesting solution for any HPC system. Of course, it must perform, as this is the most important item… according to the new publication, HPC-X does provide a performance advantage over the other commercial options, up to around 20% at 32 server nodes cluster (dual socket servers). It is definitely a good start, and am looking forward to see further reports on HPC-X. Meanwhile we do plan to download and try ourselves.
