Hi Arthur, hi all,
I guess you've got most of the thing and we'll find out the last bit, too.
Would you please let me know which version of Vampir you've got.
What does 'ls -alh' look like in the PWD? And please give it a try with some
of the included OTF tools, e.g. one of the following

To hammer this point home: Open MPI will automatically use all ACTIVE
OpenFabrics ports that it can find, regardless of whether they have IPoIB setup
on them or not.

You might want to contact Josh Hursey, the author of most of Open MPI's
checkpoint / restart / migration work; it would probably be best to ping him on
the devel list (vs. the general user's list).

You probably do want to check with your admin and ensure that either
firewalling software is disabled or that a trust relationship is setup between
the machines that you want to use. Effectively, Open MPI needs to be open
random TCP ports between all the hosts that you will be using.
There are
You need to ensure your cluster has some type of TCP connectivity. That
can be via a non-IB interface if you have that, or configure one of your
IB interfaces with IP. It is needed so the run-time environment can
start the job and exchange endpoint information to all the processes.
You do not
dear teachers:
I am a graduate .And my research is to achieve process
migratioin on openmpi.But now i find that there is few resources about internal
design of openmpi, and my work is nearly stopping. Can you help me.
A quick question. Do I need to configure different IP for both IB ports
before running mpirun?
Or configure an IP and bond both IB ports? Or simply configure one IP for
ib0 is enough?
Thanks a lot.

They will automatically be used by the library. There is nothing
special that you need to do. Unfortunately, there is no simple way to
tell if they are being used. I would suggest that you specifically call
them out in different calls to mpirun to make sure they are both
working. If they bo

Hi,
have you installed openmpi using rpm? If so, please install the
package openmpi-devel.
It has mpi.h in /usr/lib64/openmpi/1.3.2-gcc/include/mpi.h

Hi there,
We have a cluster with 2 HCAs installed on each node (Mellanox ConnectX IB
QDR cards). It's not clear from the documentation how we could use both of
them for MPI communications.
What should we do to enable 2 cards and how we can check that both are
using?
Thanks in advance!

Hello
My name is Arthur Trojanowski I just tested Vampir software.
I have installed the MPI version 1.4
I would like to know how to generate the correct OTF file in VampirTrace
I have written a small C program with support for MPI
To compile the program I use the command:
mpicc-vt -vt:inst gnu -vt
