I upgraded our servers from Centos 6.5 to Centos7.2. Since then, when I run mpirun I get the following error but the software continues to run and it appears to work fine.
* hwloc 1.11.0rc3-git 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 983 * * 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. I can replicate the error by simply running hwloc-info. The version of hwloc used with mpirun is 1.9. The version installed on the server that I ran is 1.7 that comes with Centos 7. They both give the error with minor differences shown below. With hwloc 1.7 * object (L3 cpuset 0x000003f0) intersection without inclusion! * Error occurred in topology.c line 753 With hwloc 1.9 * L3 (cpuset 0x000003f0) intersects with NUMANode (P#0 cpuset 0x0000003f) without inclusion! * Error occurred in topology.c line 983 The current kernel is 3.10.0-327.el7.x86_64. I’ve tried updating the kernel to a minor release update and even tried to install kernel v4.4.3. None of the kernels worked. Again, hwloc works fine in Centos 6.5 with kernel 2.6.32-431.29.2.el6.x86_64. I’ve attached the files generated by hwloc-gather-topology.sh. I compared what this script says is the expected output to the actual output and, from what I can tell, they look the same. Maybe I’m missing something after staring all day at the information. I did a clean install of the OS to perform the upgrade from 6.5. I’ve attached the results of the hwloc-gather-topology.sh script. Any help will be greatly appreciated.
