Hello Mahdieh, There was a related discussion recently: link<http://lists.mpich.org/pipermail/discuss/2015-September/004175.html> You may try similar approach if I’ve got your question in the correct way. BR, Dmitry From: mahdiyeh ghazi [mailto:[email protected]] Sent: Thursday, October 15, 2015 5:44 PM To: [email protected] Subject: [mpich-discuss] MPICH symmetric mode execution on Xeon Phi Hi, I'm trying to use MPICH to run a code in symmetric mode on Xeon Phi. First, I installed MPICH-3.1.4 with the following configuration for Xeon Phi: ./configure --prefix=/opt/new-mpich/mpich-3.1.4/1 --with-device=ch3:nemesis --host=x86_64 --build=x86_64-k1om-linux CC=icc CXX=icpc --disable-f77 --disable-fc CFLAGS=-mmic CXXFLAGS=-mmic --disable-mcast --disable-fortran 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 configuration, I could successfully run a code in native mode on Xeon Phi. In order to run the code in symmetric mode, I installed MPICH once again, this time for the host with following configuration: ./configure --prefix=/opt/new-mpich-host/mpich-3.1.4/1 Then I compiled the code two times, once with -mmic option to make executable for Xeon Phi (from /opt/new-mpich/mpich-3.1.4/1) and once again without -mmic option to make executable for the host (from /opt/new-mpich-host/mpich-3.1.4/1). Now, my question is how I can run the program with these two executable from Xeon Phi and the host. I know that MPICH supports running parallel programs with different executables with some devices like ch_p4, ch_mpl and globus2 using MPMD but I don't know how I can use this feature to run the code in symmetric mode on Xeon Phi and whether it is possible or not.
