(Like OpenSolaris + libtask from > Moinak is a good example) If you have a specific set of modifications in mind, then you should bring them up on freebsd-hackers, for example. There are active users of OpenMPI around ( e.g., http://www.bsdcan.org/2010/schedule/events/169.en.html , and I'm sure they would be willing to discuss improvements. >> 2) HPC ready compiler..

However, later versions of gcc are in ports, there are some discussions regarding the revival of the icc port, and there is work underway to allow users to more easily use alternative compilers and toolchains for the base system as well as for ports: http://www.freebsd.org/news/status/report-2010-01-2010-03.html#Out-of-Tree-Toolchain > >> 3) IB network drivers > >Don't know the status of Infiniband drivers, are there drivers? There is a port of of the Open Fabrics Enterprise Distribution underway: http://svn.freebsd.org/viewvc/base/projects/ofed/ And there is: http://svn.freebsd.org/viewvc/base/head/sys/contrib/rdma/ >> 4) Hardware vendor to deliver a complete solution + support >> (iXsystems?) Well, that's not up to us. All we can do is port more software and encourage people to use it. And "we" includes "you". b.
