Sorry for the delay in replying; this mail got lost in my inbox. :-(
Are you sure that this is the vanilla NPB BT benchmark? I can find
no reference to any MPI_FILE_* functions in NPB 2.3.
The error message is coming from ROMIO -- the sub-package that
implements the MPI-2 IO functionality
I have been trying to get NPB3.2.1 to run with OMPI version 1.2 over several
nodes. I have been running into the problem below.
