Hi David,
I was able to reproduce the issue you reported.
When the command line doesn't specify the components to use, ompi will try
to load/open all the ones available (and close them in the end) and then
choose the components according to their priority and whether or not they
were opened succe

Hi,
For rdmacm to work with openib btl, the first receive queue needs to be a
point-to-point queue (and not SRQ which is the default in OMPI v2.x).
Can you please try adding this parameter to the command line?
-mca btl_openib_receive_queues P,4096,8,6,4
You can change the numbers according to what

Thanks Ralph,
adding --hetero-nodes to the command line solved this issue.

Hi,
On 1.8.4rc1 we observe the following assert in the osu_mbw_mr test when
using the openib BTL.
When compiled in production mode (i.e. no --enable-debug) the test simply
hangs.
When using either the tcp BTL or the cm PML, the benchmark completes
without error.
The command line to reproduce th
Hi,
We observe a hang when running the multi-threading support test "latency.c"
(attached to this report), which uses MPI_THREAD_MULTIPLE.
The hang happens immediately at the begining of the test and is reproduced
in the v1.8 release branch.
The command line to reproduce the behavior is:
$ mpir

Hi,
I will change the default of the opal_common_verbs_want_fork_support to -1
in order to avoid these messages in case ibv_fork_init() fails.
The reason why it is failing is that ibv_fork_init() is being called to
late. To avoid this, every component should call ibv_fork_init() early in
the init
se going on that needs to be understood.
