Subject: [OMPI users] Intel MPI Benchmark(IMB) using OpenMPI - Segmentation-fault error message.
From: Mukesh K Srivastava (srimks11_at_[hidden])

Hi.

I am using IMB-3.1, an Intel MPI Benchmark tool with OpenMPI(v-1.2.5). In
/IMB-3.1/src/make_mpich file, I had only given the decalartion for MPI_HOME,
which takes care for CC, OPTFLAGS & CLINKER. Building IMB_MPI1, IMP-EXT &
IMB-IO happens succesfully.

I get proper results of IMB Benchmark with command "-np 1" as mpirun
IMB-MPI1, but for "-np 2", I get below errors -

Query#1: Any clue for above?

Query#2: How can I include seperate exe file and have the IMB for it, e.g,
writing a hello.c with MPI elementary API calls, compiling with mpicc and
performing IMB for the same exe.?
