Something is really weird here ...
right after MPI_Recv, if i
if (cstr[0] != 'H') cout << "bad first character" << endl;
then valgrind complains !
i rewrote the program in C, but if i use subroutines for send(), then
MPI_Send fail because of a NULL communicator ... if i manually inline
send(),
Davide,
you can invoke `which mpirun` instead of mpirun, or mpirun --prefix=...
an other option is to rebuild OpenMPI with --enable-mpirun-prefix-by-default

Hi all,
In our cluster the nodes are interconnected with RoCE and I want to set
up OpenMPI to run on it via SLURM.
I initially compiled OpenMPI 1.10.2 only with IB verbs support and I
have no problem making it run over RoCE.
Then I have successfully built it with SLURM support as follows:
./config
Hi all,
I have built OpenMPI 1.10.2 with RoCE network support on our test
cluster. On the cluster we use lmod to manage paths to different
versions of softwares. The problem I have is that I receive the "orted:
command not found" message given that the path to the orted binary is
not exported to th
Hi Ryan,
Unfortunately, the attachments that you shared are too low resolution to
make out the code. It sounds like you might be looking at the code in
OpenSHMEM 1.1 Section 8.1.6 (attached). Is that right?

All of those valgrind reports below are from within your code -- not from
within Open MPI.
All Open MPI can do is pass the contents of your message properly; you can
verify that it is being sent and received properly by checking the byte
contents of your received array (e.g., assert that the st

Florian,
which distro are you running on ?
if you are not using stock gcc and valgrind, can you tell which version you
are running ?
last but not least, how did you configure openmpi ?

I am still getting errors, even with your script.
I will also try to modified build of openmpi that Jeff suggested.
Best,

I was unable to reproduce this in my environment.
here is a slightly modified version of your test program.
buffers are 64 bytes aligned and the string (including the null
terminator) is 64 bytes long,
hopefully, strlen will not complain any more.
