I have a 2x6core. My solver works fine only on up to 8 processes, above that it always crashes with the below cited error. I did not yet valgrind etc. because I am in a desperate need to fix it quickly. I am just wondering what can potentially be the culprit.
PS. I am not using MPI_Allreduce anywhere in my code.
