Hi,

I'm trying to use mpich-gm on a hybrid ia32/ia64 environment and it 
looks like messages get truncated somehow.
Here is a sample run of the attached program (but this is not specific 
to MPI_Bcast, it also happens with MPI_Send/MPI_Recv).

node 0/3
Linux hpc-n04 2.4.18-e.31smp #1 SMP Wed May 21 17:47:59 EDT 2003 ia64 
unknown
node 1/3
Linux hpc-n05 2.4.18-e.31smp #1 SMP Wed May 21 17:47:59 EDT 2003 ia64 
unknown
node 2/3
Linux hpc-g01 2.4.20-31.9smp #1 SMP Tue Apr 13 17:40:10 EDT 2004 i686 
i686 i386 GNU/Linux
node 0/3  - test
node 1/3  - test
node 2/3 test - test

The setup is as follows :
- gm 2.0.8 (gm itself seems to be working fine, at least the basic 
gm_simple_example_recv.c/gm_simple_example_send.c works)
- mpich-gm 1.2.6..13b

Any insights ? Is mpich-gm supposed to work on hybrid setups ?

Thanks,
Stephane
