According to this FAQ, one should be able to compile on a computer
and then run the OMPI program on different hardware, as far as the c+
+ compiler and OMPI versions are the same: http://www.open-mpi.org/
faq/?category=sysadmin#new-openmpi-version
I have the following situation:
Server 1
Fabric: Ethernet
Compiler: g++ 4.2
OpenMPI: 1.2.8
Server 2
Fabric: InfiniBand/Ethernet
Compiler: g++ 4.2
OpenMPI: 1.2.8
Can I compile my program on Server 1 and then run it on Server 2 on
IB (mpirun --mca btl openib,self...) ?
