Hello hwloc experts I encounter this bug when I'm using mpirun or hwloc directly :
****************************************************************************
* hwloc has encountered what looks like an error from the operating system.
*
* L3 (cpuset 0x000003f0) intersects with NUMANode (P#0 cpuset 0x0000003f)
without inclusion!
* Error occurred in topology.c line 940
*
* Please report this error message to the hwloc user's mailing list,
* along with the output from the hwloc-gather-topology script.
****************************************************************************
The output of hwloc-gather-topology is attached. The OS is Centos 7.
The tool launched with mpirun runs as expected, still the message is a bit
worrying...
I was able to avoid this message by enabling "node interleaving" in the bios
(basically disables NUMA). In my case, I got a 5% performance loss with that
setting. It could be acceptable, but I would like to understant what is going
on.
So is my motherboard / BIOS / OS buggy ?
Best regards
