Are you running interactively or by a script? I have your source command and an mpirun command (without -F) in a script and it works fine. I also have the same source command in my .bash_profile but I don't think that is relevant. Steve Steven C.

Hi everyone-

I already have a workaround, but I am puzzled as to why I need one.

If I compile with:

mpiifort -O3 -xMIC_AVX512 -mcmodel medium -shared-intel -o toys mt19937.o toys.f

and run with

source /soft/compilers/intel/compilers_and_libraries/linux/mpi/bin64/mpivars.sh mpirun -f $COBALT_NODEFILE -ppn 2 ./toys

I get the error (twice)

./toys: error while loading shared libraries: libifport.so.5: cannot open shared object file: No such file or directory

This persists when I put /soft/compilers/intel_beta/compilers_and_libraries_2017.0.042/linux/compiler/lib/intel64_lin_mic in my LD_LIBRARY_PATH, and even when I copy libifport.so.5 into the run area and put the run area in my LD_LIBRARY_PATH. Echoing $LD_LIBRARY_PATH shows that this "took".

If I instead compile with:

mpiifort -O3 -xMIC_AVX512 -static-intel -o toys mt19937.o toys.f

It runs perfectly.

Any ideas?

Cheers,

Tom
