Hello, I am trying to compile and run a sample code for a MKL PBLAS routine. I found the code herehttp://software.intel.com/en-us/articles/using-cluster-mkl-pblasscalapack-fortran-routine-in-your-c-program/ . You can find the code herepdgemv.c
I compile the code on a machine with Intel Mkl installed with the following command
mpicc -w -o pdgemv.o pdgemv.c -I/opt/intel/mkl/10.2.4.032/include -L/opt/intel/mkl/10.2.4.032/lib/em64t -lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread
and get the warning
/opt/intel/Compiler/11.1/075/lib/intel64/libimf.so: warning: warning: feupdateenv is not implemented and will always fail
Then when I try to run I get segmentation fault:
[michelec@della3 pdgemv]$ mpirun -n 2 ./pdgemvlibrdmacm: couldn't read ABI version.

Another transport will be used instead, although this may result in
lower performance.

Hello Gennady,
Thank you for your reply. Unfortunately the link didn't help: it seems to me that I have a different problem on running time. The segmentation fault occurs when "Cblacs_pinfo( &myrank_mpi, &nprocs_mpi ) ;" is called. Do you have any idea?
Thank you!
Michele
