[mvapich-discuss] MVAPICH2 support for Intel Xeon Phi

[Seyedeh Ghazimirsaeed]

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
