Hi all,



after a while, I reactivated my cluster and I realized that I get the following error while running snappyHexMesh in parallel:

cfd@OpenFOAM:~/OpenFOAM/cfd-dev/run/Columbia/detailedCFDAnalysis$ mpirun -np 20 snappyHexMesh -parallel 
****************************************************************************
* hwloc 1.11.2 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 1046
*
* 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 output+tarball generated by the hwloc-gather-topology script.

However, the meshing application is running and everything seems fine but I don't know if I have to take the error serious or not. With the information given here (https://www.open-mpi.org/projects/hw...1.3/a00030.php), I cannot make any statement.

Any suggestion?
