Encountered a problem when trying to run OpenMPI 1.5.4 with RoCE over 10GbE
fabric.
Got this run time error:
An invalid CPC name was specified via the btl_openib_cpc_include MCA
parameter.
Local host: atl3-14
btl_openib_cpc_include value: rdmacm
Invalid name:
Thanks,
I am using non-blocking MPI_Isend to send out message and using blocking
MPI_Recv to get the message.
Each MPI_Isend use a distinct buffer to hold the message, which is not changed
until the message is received.
Then, the sender process waits for the MPI_Isend to be finished.
Be
You can use a debugger (just gdb will do, no TotalView needed) to find
out which MPI send & receive calls are hanging the code on the
distributed cluster, and see if the send & receive pair is due to a
problem described at:
Deadlock avoidance in your MPI programs:

Hi,
I have a Open MPI program, which works well on a Linux shared memory multicore
(2 x 6 cores) machine.
But, it does not work well on a distributed cluster with Linux Open MPI.
I found that the the process sends out some messages to other processes, which
can not receive them.
What is th
Thank you for all this information.
Your diagnosis is totally right. I actually sent e-mail yesterday but
apparently it never got through :<
It IS the MPI application that is failing to link, not OpenMPI itself; my
e-mail was not well written; sorry Brice.
The situation is this: I am trying to
I think the issue here is that it's linking the *MPI application* that is
causing the problem. Is that right?
If so, can you send your exact application compile line, and the the output of
that compile line with "--showme" at the end?

Hello,
first, please consider that the VT versions integrated in Open MPI v1.5.x and
v1.4.x are different - respectively the names of the environment variables for
setting a pre-created symbol list:
Open MPI v1.4.x: VT_NMFILE
Open MPI v1.5.x: VT_GNU_NMFILE
Furthermore, make su
