According to https://svn.open-mpi.org/trac/ompi/milestone/Open%20MPI%201.3 very soon, but you can download trunk version http://www.open-mpi.org/svn/ and check if it works for you.
how can you check mapping CPUs by OS , my cat /proc/cpuinfo shows very little info # cat /proc/cpuinfo processor : 0 cpu : Cell Broadband Engine, altivec supported clock : 3200.000000MHz revision : 48.0 (pvr 0070 3000) processor : 1 cpu : Cell Broadband Engine, altivec supported clock : 3200.000000MHz revision : 48.0 (pvr 0070 3000) processor : 2 cpu : Cell Broadband Engine, altivec supported clock : 3200.000000MHz revision : 48.0 (pvr 0070 3000) processor : 3 cpu : Cell Broadband Engine, altivec supported clock : 3200.000000MHz revision : 48.0 (pvr 0070 3000) timebase : 26666666 platform : Cell machine : CHRP IBM,0793-1RZ On Thu, Oct 23, 2008 at 3:00 PM, Mi Yan <mi...@us.ibm.com> wrote: > Hi, Lenny, > > So rank file map will be supported in OpenMPI 1.3?
