Re: [hwloc-users] Travis CI unit tests failing with HW "operating system" error

2018-09-14 Thread Jeff Hammond 
With HWLOC_COMPONENTS=no_os, MPICH is now working fine but all tests now
fail with Open-MPI (see below).  I know how to resolve this, but am noting
it for the benefit of others.

All nodes which are allocated for this job are already filled.

We will upgrade the hwloc submodule used in MPICH asap. IIRC, we have supressed 
hwloc warnings as well. I will double check this.

As a workaround for ARMCI, you may try setting HWLOC_COMPONENTS=no_os,stop in 
the environment so that hwloc behaves as if the operating system had no 
topology support.

All of the job failures have this warning so I am inclined to think they
are related.  I don't know what I should expect from lstopo on inside of
AWS, but I guess I'll try it.

I was using the hwloc shipped with the mpich-3.3b1.  Talk to the MPICH team
if you want them to upgrade :-)

2018-09-13 Thread Brice Goglin 
This is actually just a warning. Usually it causes the topology to be
wrong (like a missing object), but it shouldn't prevent the program from
working. Are you sure your programs are failing because of hwloc? Do you
have a way to run lstopo on that node?

By the way, you shouldn't use hwloc 2.0.0rc2, at least because it's old,
it has a broken ABI, and it's a RC :)

[hwloc-users] Travis CI unit tests failing with HW "operating system" error

2018-09-13 Thread Jeff Hammond 
I am running ARMCI-MPI over MPICH in a Travis CI Linux instance and
topology is causing it to fail.  I do not care about topology in a
virtualized environment.  How do I fix this?


* hwloc 2.0.0rc2-git has encountered what looks like an error from the
operating system.
*
* Group0 (cpuset 0x,0x) intersects with L3 (cpuset
0x1000,0x0212) without inclusion!
* Error occurred in topology.c line 1384
*
* The following FAQ entry in the hwloc documentation may help:
*   What should I do when hwloc reports "operating system" warnings?
* Otherwise please report this error message to the hwloc user's mailing
list
* along with the files generated by the hwloc-gather-topology script.
