I was trying to use hints with ROMIO and lustre prompted by another post on
this list.
I have a simple MPI-IO code and I cannot using the notes I find set the lustre
striping using the config file and setting ROMIO_HINTS.
Question:
How can I check which ADIO drivers ROMIO in OPenMPI was built with when I built
it?
Can I make ROMIO go into 'verbose' mode and have it print what it is setting
all its values to?
Try "ompi_info -a" and check for lustre in the output:
ompi_info -a | grep -i romio
...
MCA io: information "io_romio_user_configure_params"
(value: <--with-file-system=testfs+ufs+nfs+lustre>, data source: default
value)
User-specified command line parameters passed
to ROMIO's configure script
MCA io: information
