If I understand your question correctly, this is *exactly* one of the reasons
that the MPI Forum has been arguing about the use of a new type, "MPI_Count",
for certain parameters that can get very, very large.

Sidenote: I believe that a workaround for you is to create some new MPI

Yes -- check out the README; there's a section on MTLs vs. BTLs.
If that's not clear, post back here and we can explain further (and update the
README :-) ).

Hi Rolf,
I double checked the flag just now. It was set correctly, but the hanging
problem is still there.
But I found another way to solve the hanging problem. Just setting environment
CUDA_NIC_INTEROP 1
could solve the issue.
Thanks,

Hi Fengguang:
That is odd that you see the problem even when running with the openib flags
set as Brice indicated. Just to be extra sure there are no typo errors in your
flag settings, maybe you can verify with the ompi_info command like this?
ompi_info -mca btl_openib_flags 304 -param btl ope

I try to compile open-mpi with ifort 12.0.4. My system is ubuntu
lucid. Previous intallation with ifort 11.1 was fine.
configure and make all seems to work well, but make install report an error:

Hello!
The problem I face is not open-mpi specific, but I hope still the MPI
wizards on the list can help me nonetheless.
I am running and developing a large-scale scientific code written in
Fortran90. One type of objects are global 1-D vectors, which contains
data for particles in the appli
