I'm no MPI guru, nor do I completely understand what you are doing, but

Jeff thanks for the clarification,
What I am trying to do is run N concurrent copies of a 1 to N data movement
program to affect an N to N solution. The actual mechanism I am using is to
spawn N copies of mpirun from PVM across the cluster. So each 1 to N MPI
application starts at the same time
Hi Jeff
Thank you for opening a ticket and taking care of this.

after updating to a newer kernel on ubuntu server nodes, sm is not a

my older kernel, was

Solved: The process to core locking was due to affinity being set at
the PSM layer. So I added -x IPATH_NO_CPUAFFINITY=1 to the mpirun
command.

+1 on Eugene's comment that I don't fully understand what you are trying to do.
Can you send a short example code?
Some random points:
- Edgar already chimed in about how MPI-2 allows the use of intercommunicators
with bcast. Open MPI is MPI-2.1 complaint, so you can use intercommunicators

Boost.MPI is layered on top of plain MPI; it basically provides a
mapping from complex and user-defined C++ data types to MPI datatypes.

Hi Riccardo,
Are the Boost.MPI send and recv functions as fast as the standard ones when
using Open-MPI?

you have any questions in reproducing the hang.

sorry, i just forgot to add the values of the function parameters:

Hi Mike,
The HCA card is a Mellanox Technologies MT25418 (ConnectX IB DDR, PCIe 2.0
2.5GT/s, rev a0).
I cannot post code/instructions how to reproduce these errors as they randomly
appeared during some tests I've performed to locate the origin of a
segmentation fault during an MPI collective ca
Hey Eloi,
What HCA card do you have ? Can you post code/instructions howto reproduce
it?

Hi,
I just stumped into the following behavior of Open MPI 1.4.2. Used jobscript:
***
#!/bin/sh
export PATH=~/local/openmpi-1.4.2/bin:$PATH
cat $PE_HOSTFILE
mpiexec ./dummy.sh
***
with dummy.sh:
***
#!/bin/sh
env | grep TMPDIR
sleep 30
