Dear PwScf users, I am getting MPI error during PWCOND run at particular point. The standard output gives:
MPI_Allreduce: invalid communicator: Unknown error 2064 (rank 0, comm 16) Rank (0, MPI_COMM_WORLD) : Call stack within LAM: Rank (0, MPI_COMM_WORLD) : -MPI_Allreduce() Rank (0, MPI_COMM_WORLD) : -main() ------------------------------------------------------ One of the processes started by mpirun has exited with a nonzero exit........ ... .. .. PID 16077 failed on node n1 (192.168.0.12) with exit status 1. ----------------------------- I am running espresso-4.0 installed with lam-mpi 7.1.4 and ifort 10.1 on dual cpu quad core xeon processors. There are 2 machines running in parallel. Thus 4 cpus or 16 cores are available. However, this calculation was ran on 4 cores only. The scf and relax calculations do not crash. One more thing to note is: recently I have enhanced RAM on both the machines. And after enhnacement did not do any reinstallation or recompilation of any software including lam-mpi. Note : Through search on forum archives I found a post by Derek : http://www.democritos.it/pipermail/pw_forum/2005-November/003219.html which indicates this might be a problem related to mpi or def.h......
