Hi Ralph, Thanks for that... that option's not on the man page for mpirun, but I can see it in the --help message (as "overload-allowed", which also works). Cheers, Ben -Original Message- From: devel [mailto:devel-boun...@lists.open-mpi.org] On Behalf Of r...@open-mpi.org Sent:

Karol, it is correct vampirtrace was removed from Open MPI 2.0.0 are you using your own (or openSUSE) .spec file ? or the one provided by Open MPI ? fwiw, Open MPI 1.10.4 and 2.0.1 should be released in a near future. Cheers, Gilles On 8/25/2016 10:24 AM, Karol Mroz wrote:

Giles, I have successfully built openmpi-v2.0.0-227-g917d293 (tonight's nightly tarball) on Solaris 11.3 with both the Gnu and Studio compilers. Based on Ralph's previous email, I assume that included the patch you had directed me to (though I did not attempt to verify that myself). -Paul On

Re: [OMPI devel] Upgrading our (openSUSE) Open MPI version

Hi Gilles, Thanks for the speedy reply. I'm using our existing spec file. Tumbleweed is meant to be a rolling distribution, so I think 2.0.0 fits well. I can always upgrade the package when 2.0.1 comes out. For our Leap distribution, a more mature 1.10.x fits. Thanks for confirming VT is out

Okay, I found the issue and fixed it: https://github.com/open-mpi/ompi-release/pull/1340 We are very close to v2.0.1 release, so it may not get into that one. Still, you are welcome to pull down the patch and locally apply it if it would help. Ralph > On Aug 24, 2016, at 5:29 PM,

[OMPI devel] Upgrading our (openSUSE) Open MPI version

Greetings! I would like to upgrade our (openSUSE Tumbleweed) version of Open MPI from 1.10.3 to the shiny new 2.0.0 :) This is motivated by a number of factors, including an upgrade to glibc2.24 which breaks our current build of Open MPI. I thought it a great time to push out a new version :D

[OMPI devel] Binding with --oversubscribe in 2.0.0

Hi, One of our users has noticed that binding is disabled in 2.0.0 when --oversubscribe is passed, which is hurting their performance, likely through migrations between sockets. It looks to be because of 294793c (PR#1228). They need to use --oversubscribe as for some reason the developers

Re: [OMPI devel] Binding with --oversubscribe in 2.0.0

Well, that’s a new one! I imagine we could modify the logic to allow a combination of oversubscribe and overload flags. Won’t get out until 2.1, though you could pull the patch in advance if it is holding you up. > On Aug 23, 2016, at 11:46 PM, Ben Menadue wrote: > >

Re: [OMPI devel] Binding with --oversubscribe in 2.0.0

Actually, I stand corrected! Someone must have previously requested it, because support already exists. What you need to do is simply specify the desired binding. If you don’t specify one, then we will disable it by default when oversubscribed. This was done to protect performance for those
