Problem in HWLOC

Clicked A Few Times	9:16:05 AM PST - Sat, Dec 13th 2014 Hello, I am having some difficulty running NWChem on a 24 core AMD computer. I get the following repeatedly: hwloc has encountered what looks like an error from the operating system. object (L3 cpuset 0x000003f0) intersection without inclusion! Error occurred in topology.c line 853 Please report this error message to the hwloc user's mailing list, along with the output from the hwloc-gather-topology.sh script. hwloc has encountered what looks like an error from the operating system. object (L3 cpuset 0x000003f0) intersection without inclusion! Error occurred in topology.c line 853 Please report this error message to the hwloc user's mailing list, along with the output from the hwloc-gather-topology.sh script. Installation went well, so there should be something wrong with the file? It is generated in Avogadro. Thanks

Forum Vet	9:17:27 PM PST - Tue, Dec 16th 2014 Senmen I have noticed that there are some posts reporting similar hwloc error messages on the OpenMPI mailing list. If you are indeed using OpenMPi, the OpenMPI forum might be a better place to ask for help. Edo

Clicked A Few Times	10:43:00 AM PST - Fri, Dec 19th 2014 Hi Edo, I uninstalled Open MPI, so it should not be active . However, does NWChem and Ecce have a way to bypass Open mpi? (use an alternative eventually) Thanks

Forum Vet	11:05:20 AM PST - Fri, Dec 19th 2014 Semmen You need a working MPI installation to use NWChem. It could be either Mpich, OpenMPi or whatever you prefer.

Clicked A Few Times	12:00:20 PM PST - Fri, Dec 19th 2014 Hi Edo, it seems Open mpi doesn work at all. Installed version 1.8.3 with no problems, and the error changed to : Hwloc has encountered what looks like an error from the operating system. object intersection without inclusion! Error occurred in topology.c line 594 Please report this error message to the hwloc user's mailing list, along with the output from the hwloc-gather-topology.sh script. Should I install mpich? Will NWCHem automatically use MPICH?

Clicked A Few Times	3:07:33 AM PST - Sat, Dec 20th 2014 Running NWCHEm Dear Edo, I took Mernst advice on using the debian version of NWchem instead of the recent 6.5, in order to avoid this problem with open mpi. It worked. i am however curious if there is a way to update the debian version to the 6.5 version without destroying the well-working mpi configuration? thanks
