Re: [OMPI users] Error building openmpi on Raspberry pi 2

Faraz, which OS are you running ? iirc, i faced similar issues, and the root cause is that though ARMv7 does support these instructions, the compiler only generate ARMv6 code and hence failed to build Open MPI Cheers, Gilles On Wed, Sep 27, 2017 at 10:32 AM, Faraz Hussain

Re: [OMPI users] Fwd: OpenMPI does not obey hostfile

Anthony, a few things ... - Open MPI v1.10 is no more supported - you should at least use v2.0, preferably v2.1 or even the newly released 3.0 - if you need to run under torque/pbs, then Open MPI should be built with tm support - openhpc.org provides Open MPI 1.10.7 with tm support Cheers,

Re: [OMPI users] Fwd: OpenMPI does not obey hostfile

This is not explained in the manual, when giving a hostfile (though I was suspecting that was the case). However running one process on each node listed WAS the default behaviour in the past. In fact that is the default behaviour on a old Version 1.5.4 OpenMPI, I have on an old cluster which I

Re: [OMPI users] Fwd: OpenMPI does not obey hostfile

That is correct. If you don’t specify a slot count, we auto-discover the number of cores on each node and set #slots to that number. If an RM is involved, then we use what they give us Sent from my iPad > On Sep 26, 2017, at 8:11 PM, Anthony Thyssen > wrote: > >

[OMPI users] Fwd: OpenMPI does not obey hostfile

I have been having problems with OpenMPI on a new cluster of machines, using stock RHEL7 packages. ASIDE: This will be used with Torque-PBS (from EPEL archives), though OpenMPI (currently) does not have the "tm" resource manager configured to use PBS, as you will be able to see in the debug
