FDSim

Dear Sir
While we are running FDMod3D executable file on a HPC computing facility, we face this error which I have attached to this email. Please help us if you know what we have to do. We could define the path for dynamic libraries but segmentation fault still exists. The HPC Linux is CentOS and we use gfortran as compiler and openmpi to implement parallel processing. We compiled and run FDMod3D with these three lines in Makefile:

FD = mpif90
FFLAGS = -cpp -O3 -DUSE_MPI -DMPI2
LDFLAGS = -O3

I am looking forward to hear from you.

Best Regards,
Siavashpour

Dear Siavashpour,

in addition to the attached screenshot, could you also include information about how you started the program?

Dear Dr. Galis
I started it with ./FDMod3D but now I start it with mpirun -np 8 ./FDMod3D and the problem solved. Now I have a problem in running FDSim3D which I have explained it in another post.

Regards,
Siavashpour
