Hi all, The compilation of a fortran application - CPMD-3.13.2 - with OpenMP + OpenMPI-1.3.3 + ifort-10.1 + MKL-10.0 is failing with following error on a Rocks-5.1 Linux cluster:
/lib/cpp -P -C -traditional -D__Linux -D__PGI -DFFT_DEFAULT -DPOINTER8 -DLINUX_IFC -DPARALLEL -DMYRINET ./potfor.F ./potfor.f /opt/mpi/openmpi/1.3.3/intel/bin/mpif90 -c -pc64 -O3 -xT -unroll -openmp ./potfor.f -o ./potfor.o fortcom: Severe: **Internal compiler error: segmentation violation signal raised** Please report this error along with the circumstances in which it occurred in a Software Problem Report. Note: File and line given may not be explicit cause of this error. compilation aborted for ./potfor.f (code 3) make: *** [potfor.o] Error 3 But if the potfor.f is compiled by removing -openmp option, then it compiles successfully. But while running it again failed with "Aborted" message. The interesting thing is, the same application compiles and runs fine with IntelMPI on another cluster with exactly the same environment. What's here the issue with Open MPI? Thanks, Sangamesh
