Hi, I'm trying to use periodic boundary conditions with mpi, and the code works well when I use up to 8 CPUs. However, when I try using more CPUs, the code crashes with the error:
mpirun noticed that process rank 0 with PID 9529 on node exited on signal 11. It crashes at the line sparsity_tools::distribute_sparsity_pattern. I went trough sparsity_tools.cc and it looks like two different strategies are being used for number of partitions being below or above 8 (recursive and kway), and was wondering maybe that is related to the source of problem. I'm able to run the same code with more than 8 CPUs if I don't use periodic boundary conditions. Has anyone encountered the same problem? Any suggestions?
