Hi,
I am trying to use the rankmap to bind a 4-proc mpi job to one socket of a
two-socket, 8 core machine. However I'm getting a strange error.
CMDS USED
orterun --hostfile hostlist.1 -n 4 --mca rmaps_rank_file_path ./rankmap.1
desres-netscan -o $OUTDIR
$ cat rankmap.1
rank 0=drdb0235.en

Hi,
We are migrating to openmpi on our large (~1000 node) cluster, and plan
to use it exclusively on a multi-thousand core infiniband cluster in the
near future. We had extensive problems with parallel processes not dying
after a job crash, which was largely solved by switching to the slurm

To keep this out of the weeds, I have attached a program called "bug3"
that illustrates this problem on openmpi 1.2.5 using the openib BTL. In
bug3 process with rank 0 uses all available memory buffering
"unexpected" messages from its neighbors.
Bug3 is a test-case derived from a real, scalable ap
Hi,
I am readying an openmpi 1.2.5 software stack for use with a
many-thousand core cluster. I have a question about sending small
messages that I hope can be answered on this list.
I was under the impression that if node A wants to send a small MPI
message to node B, it must have a credit to do
