Re: [OMPI users] Issues with different IB adapters and openmpi 2.0.2

Hi Orion Does the problem occur if you only use font2 and 3? Do you have MXM installed on the font1 node? The 2.x series is using PMIX and it could be that is impacting the PML sanity check. Howard Orion Poplawski schrieb am Mo. 27. Feb. 2017 um 14:50: > We have a

[OMPI users] Issues with different IB adapters and openmpi 2.0.2

We have a couple nodes with different IB adapters in them: font1/var/log/lspci:03:00.0 InfiniBand [0c06]: Mellanox Technologies MT25204 [InfiniHost III Lx HCA] [15b3:6274] (rev 20) font2/var/log/lspci:03:00.0 InfiniBand [0c06]: QLogic Corp. IBA7220 InfiniBand HCA [1077:7220] (rev 02)

Re: [OMPI users] Fwd: [OMPI USERS] Fault Tolerance and migration

Alberto, In the master there is no such support (we had support for migration a while back, but we have stripped it out). However, at UTK we developed a fork of Open MPI, called ULFM, which provides fault management capabilities. This fork provides support to detect failures, and support for

[OMPI users] Does MPI_Iallreduce work with CUDA-Aware in OpenMPI-2.0.2?

Hi list, I would like to know if MPI_Iallreduce is supported with cuda-aware in openMPI-2.0.2? The page https://www.open-mpi.org/faq/?category=runcuda, updated on 06/2016, says not supported until openmpi--1.8.5. Any updates on this? Thank you Junjie Qian

Re: [OMPI users] fatal error with openmpi-2.1.0rc1 on Linux with Sun C

Drat! Thanks for letting us know. That fix was missed when we swept through to create the PMIx v1.2.1 - which triggered the OMPI v2.1.0rc1. Sorry about that :( Jeff filed an Issue to track this here: https://github.com/open-mpi/ompi/issues/3048 I've filed a PR against PMIx to bring it into the

[OMPI users] Fwd: [OMPI USERS] Fault Tolerance and migration

Hi, I am interested in using OpenMPI to manage the distribution on a MicroZed cluster. This MicroZed boards come with a Zynq device, which has a dual-core ARM cortex A9. One of the objectives of the project I am working on is resilience, so I am trully interested in the fault tolerance provided by

[OMPI users] fatal error with openmpi-2.1.0rc1 on Linux with Sun C

Hi, I tried to install openmpi-2.1.0rc1 on my "SUSE Linux Enterprise Server 12.2 (x86_64)" with Sun C 5.14. Unfortunately, "make" breaks with the following error. I had reported the same problem for openmpi-master-201702150209-404fe32. Gilles was able to solve the problem
