Okay, thanks - I'll give it a try.

AMPI includes a mpiio (romio) library. To compile it, cd
charm/mpi-crayxt/tmp/lib/ck-libs/ampi

and run command:

make AMPI-ROMIO

If you are using an old version of charm, you need to update
romio/config.sh to be like this:

#!/bin/sh
CHARMDIR=`util/charmdir`
./configure -mpiincdir=$CHARMDIR/include
-mpilib=$CHARMDIR/lib/libmoduleampi.a -mpibindir=$CHARMDIR/bin
-cc=$CHARMDIR/bin/ampicc -fc=$CHARMDIR/bin/ampif77
-f90=$CHARMDIR/bin/ampif90

(using ampicc instead of mpicc for example)
