Re: [OMPI users] Oversubscribing When Running Locally

Benjamin, There was no need to open a new thread with the same title and a slightly modified question, it just added some confusion. If you want to allow oversubscription by default, you can insert the following line in your /etc/openmpi-mca-params.conf (update the path if needed)

#2 and #3 are OK About #1, we could rename pkgconfig and pkgdata prefixes into something like hwlocpkgconfig and hwlocpkgdata. I don't think the actual prefix value matters. I'll try that tomorrow. Brice Le 24/01/2018 à 23:46, Balaji, Pavan a écrit : > Hi Brice, > > Here are the other patches

Hi Brice, Here are the other patches that we are currently maintaining for hwloc. Can you see if these can be integrated upstream too: https://github.com/pmodels/hwloc/commit/44fe0a500e7828bcb2390fbd24656a7a26b450ed

[OMPI users] Oversubscribing When Running Locally

Re: [hwloc-users] OFED requirements for netloc

OK In the meantime, maybe you can diff the ibnetdiscover outputs to see if anything obvious appears? You might need to sort the lines first if the outputs aren't ordered the same. Brice Le 24/01/2018 à 23:33, Craig West a écrit : > Brice, > > The output isn't big, just a pair of IB switches

Re: [hwloc-users] OFED requirements for netloc

Brice, The output isn't big, just a pair of IB switches and a dozen hosts, some with single, some dual connections. However, we would need to sanitise the data, or at least look at it in detail first to see what it contains. I can say that the ibnetdiscover and ibroute commands report version
