[OMPI users] Silent hangs with MPI_Ssend and MPI_Irecv

2020-07-24 Thread Lewis,Sean via users
Hi all, I am encountering a silent hang involving MPI_Ssend and MPI_Irecv. The subroutine in question is called by each processor and is structured similar to the pseudo code below. The subroutine is successfully called several thousand times before the silent hang behavior manifests and never

Hi Currently i am approaching a similar problem/workflow with spack and an AWS S3 shared storage. Mounting the storage from a laptop gives you same layout as on each node of my AWC EC2 cluster. As others mentioned before: you still have to recompile your work, to take advantage of the XEON class c

+1 In my experience moving software, especially something of the complexity of (Open) MPI, is much more troublesome (and often just useless frustration) and time consuming than recompiling it. Hardware, OS, kernel, libraries, etc, are unlikely to be compatible. Gus Correa On Fri, Jul 24, 2020 at 1

Hi, Chris, The website you gave is almost empty. svn checkout https://scm.projects.hlrs.de/anonscm/svn/mpitestsuite/ does not work. Our code uses MPI point to point, collectives, and communicator, attributes, basically MPI-2.1 stuff. Thanks --Junchao Zhang On Jul 24, 2020, at 2:34 AM,
