I am again trying to build and run the Nasa Overflow 1.8ab version using Open MPI and have run into this error message :
[hsd653:05053] *** An error occurred in MPI_Allreduce: the reduction operation M PI_OP_MIN is not defined on the MPI_DBLPREC datatype [hsd653:05053] *** on communicator MPI_COMM_WORLD [hsd653:05053] *** MPI_ERR_OP: invalid reduce operation [hsd653:05053] *** MPI_ERRORS_ARE_FATAL (goodbye) [hsd652:04317] *** An error occurred in MPI_Allreduce: the reduction operation M PI_OP_MIN is not defined on the MPI_DBLPREC datatype [hsd652:04317] *** on communicator MPI_COMM_WORLD [hsd652:04317] *** MPI_ERR_OP: invalid reduce operation [hsd652:04317] *** MPI_ERRORS_ARE_FATAL (goodbye) mpirun: killing job... ------------------------------------------------------------------------ -- WARNING: mpirun encountered an abnormal exit. This means that mpirun exited before it received notification that all started processes had terminated. You should double check and ensure that there are no runaway processes still executing. Any ideas why this is happening?? Bernie Borenstein The Boeing Company
