Eric,

You are correct, our builds do not show lustre support:

  MCA io: information "io_romio_user_configure_params" (value:<none>, data 
source: default value)
surprise! ;-)

So to enable this, when I build OpenMPI I should pass:

--with-io-romio-flags='--with-file-system=testfs+ufs+nfs+lustre'
exactly.

We have Lustre, local filesystems (ufs), and NFSv3 and NFSv4 clients. So that 
list should be good for our site.

Would this be a good recommendation for us to include in all our MPI builds?
I think yes, it is in the right direction, but I am not an "expert"... some expert advice should be welcome.

Eric

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
...
