Hi everyone, I have a weird problem using meep-mpi/meep on a 32-core,64gb RAM, 64bit system. It seems that after I started meep-mpi e.g. with 8 processes, one or sometimes two processes will leap behind in run time. When meep should be finished, all processes go to sleep except those two. They will run indefinitely and must be terminated by hand. If I check the meep output, sometimes everything looks fine (last line: elapsed run time=....) but sometimes it stops right after harminv! This problem occurs just occasionally, sometimes everything works just as it should.
I have experienced the same problem with meep, so i think it's not the MPI. I already checked for hardware issues and found none, i also ran the very same files on an 8-core 32bit system and they worked just fine! So maybe it's some problem with my harminv installation on 64bit? If anyone has experienced similar issues or has any hints i would be very thankful!
