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

[hsd653:05053] *** on communicator MPI_COMM_WORLD

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??
