[mvapich-discuss] Intel Xeon Phi support?

[Nikoloutsakos Nikolaos]

Hello again,

Thanks a lot for the hints, it was very helpful !
I need a little more help.

Here is the steps i followed:

1: Configure MVAMPICH with MIC support
./configure --prefix=/opt/mvapich_icc_mic/ --disable-mcast --disable-fc 
--disable-f77 --host=i686-linux-gnu --build=x86_64-k1om-linux CC=icc 
CXX=icpc CFLAGS=-mmic CXXFLAGS=-mmic 
LDFLAGS='-L/opt/intel/composer_xe_2013_sp1.2.144/compiler/lib/mic/ 
-Wl,-rpath,/opt/intel/composer_xe_2013_sp1.2.144/compiler/lib/mic/'

2: Compile my code on host machine

/opt/mvapich_icc_mic/bin/mpicc -mmic mpi_hello_world.c 
-L/opt/intel/composer_xe_2013_sp1.2.144/compiler/lib/mic/ 
-Wl,-rpath,/opt/intel/composer_xe_2013_sp1.2.144/compiler/lib/mic/

3: Copy/Mount libraries on MIC
mount host:/opt/mvapich_icc_mic/ /opt/mvapich_icc_mic/

4: Run on MIC

/opt/mvapich_icc_mic/bin/mpiexec -n 1 ./a.out
librdmacm: couldn't read ABI version.
librdmacm: assuming: 4
CMA: unable to get RDMA device list
Hello world from processor cedar-mic0, rank 0 out of 1 processors

So is this a problem with my MVAPICH setup or with my xeon phi 
configuration?

Hope to figure this out, thanks for the help.

Bye,
Nikos
