Thanks for your reply.
Although MVAPICH2-MIC is tuned for Xeon Phi clusters, I was looking for open source implementation of MPI so I was trying to use MVAPICH2. I know that MVAPICH2 is not efficient on Xeon Phi clusters, but does it mean that it cannot be used to run a simple code on Xeon Phi?
Thanks,
Mahdieh

Support for Intel Xeon Phi is available with MVAPICH2-MIC library, not the basic MVAPICH2 library.
Please feel free to download and use MVAPICH2-MIC 2.0 version.

Hi,
I want to use MVAPICH2 2.2a on the Intel Xeon Phi co-processor. Here is my config:
./configure --prefix=/opt/new-mv/12 --disable-mcast --disable-fc --disable-f77 --disable-fortran --host=x86_64 --build=x86_64-k1om-linux CC=icc CXX=icpc CFLAGS=-mmic CXXFLAGS=-mmic LDFLAGS='-L/home/ghazim/build/aster/intel/composer_xe_2015.3.187/compiler/lib/mic/ -Wl,-rpath,/home/ghazim/build/aster/intel/composer_xe_2015.3.187/compiler/lib/mic/'
with this configure, I can compile the code with -mmic without any error but when I want to run it, I get this error:
#/opt/new-mv/12/bin/mpicc -mmic -o /opt/new-mv/12/bin/hellomic /opt/new-mv/12/bin/hellompi.c
#/opt/new-mv/12/bin/mpirun -host aster-mic0 -n 2 /opt/new-mv/12/bin/hellomic
/opt/new-mv/12/bin/mpirun: cannot execute binary file
I get this error even if I compile the code for the host (without -mmic).
Please let me know if you have any suggestions.
Thanks,
Mahdieh
