MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode -1 #4

Closed Gweiqi closed 4 years ago

Gweiqi commented 4 years ago

Dear hemelb Users and Developers! When I run the example "bifurcation_hires", I get this error： MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode -1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes. You may or may not see output from other processes, depending on exactly when Open MPI kills them.

I am a beginner and this question has been bothering me for a long time and I am eager to get your help! Many thanks, Guo Weiqi

Can you post the whole log please? HemeLB will print an error message immediately before calling MPI_Abort.

The last line tells you the problem: the output directory exists. HemeLB will refuse to overwrite existing results.
