Re: [OMPI devel] Process placement

I believe this has been fixed. Note that the allocation display occurs prior to mapping, and thus the slots_inuse will be zero at that point. You’ll see those numbers change if you do a comm_spawn, but otherwise they will always be zero > On May 5, 2016, at 8:37 PM, Ralph Castain

Okay, I see it - will fix on Fri. This is unique to master. > On May 5, 2016, at 1:54 PM, Aurélien Bouteiller wrote: > > Ralph, > > I still observe these issues in the current master. (npernode is not > respected either). > > Also note that the display_allocation seems

Re: [OMPI devel] Process placement

Ralph, I still observe these issues in the current master. (npernode is not respected either). Also note that the display_allocation seems to be wrong (slots_inuse=0 when the slot is obviously in use). $ git show 4899c89 (HEAD -> master, origin/master, origin/HEAD) Fix a race condition

The —map-by node option should now be fixed on master, and PRs waiting for 1.10 and 2.0 Thx! > On Apr 12, 2016, at 6:45 PM, Ralph Castain wrote: > > FWIW: speaking just to the —map-by node issue, Josh Ladd reported the problem > on master as well yesterday. I’ll be looking

FWIW: speaking just to the —map-by node issue, Josh Ladd reported the problem on master as well yesterday. I’ll be looking into it on Wed. > On Apr 12, 2016, at 5:53 PM, George Bosilca wrote: > > > > On Wed, Apr 13, 2016 at 1:59 AM, Gilles Gouaillardet

[OMPI devel] Process placement

I noticed that my old scheme of process placement seems to be have a different outcome with the current master. I used to start a single process per node on my cluster using a hostfile together with “map-by node”, with a command line that looked like this “mpirun —hostfile arc —map-by node -np
