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.
