Here's what I used to build 1.8.1 with Intel 13.5 recently: module load compiler/13.5.192 export PATH=/usr/linux-k1om-4.7/bin/:$PATH ../configure --prefix=/path/to/your/ompi/install \ CC="icc -mmic" CXX="icpc -mmic" \ --build=x86_64-unknown-linux-gnu --host=x86_64-k1om-linux \ AR=x86_64-k1om-linux-ar RANLIB=x86_64-k1om-linux-ranlib \ LD=x86_64-k1om-linux-ld \ --enable-mpirun-prefix-by-default --disable-io-romio \ --disable-vt --disable-mpi-fortran \ --enable-mca-no-build=btl-usnic,btl-openib,common-verbs make make install
Problem with this is that you get a mpicc that must run on MIC, while you want a host-mpicc that generates MIC code. $ ssh mic0 $ <put your icc compiler stuff in the environment> $ /path/to/your/ompi/install/bin/mpicc --show icc -mmic -I/home/goglin/mic/openmpi-1.7.4/build-mic/install/include \ -pthread -Wl,-rpath -Wl,/home/goglin/mic/openmpi-1.7.4/build-mic/install/lib \ -Wl,--enable-new-dtags -L/home/goglin/mic/openmpi-1.7.4/build-mic/install/lib \ -lmpi Now use the above line as mpicc on the host to build for the MIC. But I had to append this: -Wl,-rpath -Wl,/opt/cluster/intel/composer_xe_2013.5.192/compiler/lib/mic/ \ -L/opt/cluster/intel/composer_xe_2013.5.192/compiler/lib/mic/ I hoped WRAPPER_* configure variables would help solving all this, but I couldn't make them work.
