Good catch, George - thanks for the detailed explanation. I think what
happened here was that we changed the ordering in MPI_Init a while back -
we had always had a rule about when MPI components could access remote proc
info, but had grown lax about it, so at least some of the BTLs had to be
fixed
Juan,
Something weird is going on there. The selection mechanism for the SM coll and
SM BTL should be very similar. However, the SM BTL successfully select itself
while the SM coll fails to determine that all processes are local.
In the coll SM the issue is that the remote procs do not have the
Okay, please try this again with r26739 or above. You can remove the rest
of the "verbose" settings and the --display-map so we declutter the output.
Please add "-mca orte_nidmap_verbose 20" to your cmd line.
Thanks!
Ralph

I'll look at this more, but for now I'll just note that the new ibarrier
test is showing lots of failures on MTT (cisco and oracle).
Rats - no help there. I'll add some debug to the code base tonight that will
tell us more about what's going on here.

Here is the output.

Interesting - yes, coll sm doesn't think they are on the same node for some
reason. Try adding -mca grpcomm_base_verbose 5 and let's see why

The code I run is a simple broadcast.
When I do not specify components to run, the output is (more verbose):
[jarico@Metropolis-01 examples]$
/home/jarico/shared/packages/openmpi-cas-dbg/bin/mpiexec --mca mca_base_verbose

The issue is that the "sm" coll component only implements a few of the MPI
collective operations. It is usually mixed at run-time with other coll
components to fill out the rest of the MPI collective operations.
So what is happening is that OMPI is determining that it doesn't have
implementati

Sounds strange - the locality is definitely being set in the code. Can you run
it with -mca hwloc_base_verbose 5 --display-map? Should tell us where it thinks
things are running, and what locality it is recording.

Hello everyone. Maybe you can help me:
I got a subversion (r 26725) from the developers trunk. I configure with:
../../onecopy/ompi-trunk/configure
--prefix=/home/jarico/shared/packages/openmpi-cas-dbg --disable-shared
--enable-static --enable-debug --enable-mem-profile --enable-mem-debug CFLAG

We talked about this on the weekly call today. Conclusions:
1. Looks like we just goofed on the CQ default size values. Doh!
2. There does not appear to be any reason we're not using the device CQ max
size by default. Ticket #3152 changes the trunk to do this (and we'll CMR to
v1.6 and v1.7).
Hope to see some of you in Austria!
