Re: [OMPI users] independent startup of orted and orterun

Hi Ralph, All makes sense! Thanks a lot! Looking forward to your modifications. Please don't hesitate to through things with rough-edges to me! Cheers, Mark > On 21 Jan 2015, at 23:21 , Ralph Castain wrote: > > Let me address your questions up here so you don’t have to scan thru the > entir

Re: [OMPI users] independent startup of orted and orterun

Let me address your questions up here so you don’t have to scan thru the entire note. PMIx rationale: PMI has been around for a long time, primarily used inside the MPI library implementations to perform wireup. It provided a link from the MPI library to the local resource manager. However, as

Re: [OMPI users] independent startup of orted and orterun

Hi Ralph, all, To give some background, I'm part of the RADICAL-Pilot [1] development team. RADICAL-Pilot is a Pilot System, an implementation of the Pilot (job) concept, which is in its most minimal form takes care of the decoupling of resource acquisition and workload management. So instead of

Re: [OMPI users] independent startup of orted and orterun

Ah, I see - actually, MR+ is supported under ORTE. You just need to add the —staged option to the cmd line. You then run your job like this: mpirun —staged -n X my-mapper : -n Y my-reducer We’ll wire together the output of the mappers to the input of the reducers and run them in an appropriate

Re: [OMPI users] independent startup of orted and orterun

Hi Ralph, I figured that MR+ had to require something similar too (assuming it actually does use ORCM). Let me study that wiki a bit and I will come back with a description of my use-case. Thanks! Mark > On 21 Jan 2015, at 17:18 , Ralph Castain wrote: > > Sorry - should have included the

Re: [OMPI users] independent startup of orted and orterun

Theoretically, yes - see the ORCM project, which basically does what you ask. The launch system in there isn’t fully implemented yet, but the fundamental idea is valid and supports some range of capability. We used to have a cmd line option in ORTE for what you propose - it wouldn’t be too hard

[OMPI users] independent startup of orted and orterun

Hi, Would it be possible to initially run "idle" orted's on my resources and then use orterun to launch my applications to these already running orted's. Thanks! Mark

Thank you for help. Now it works. Klara Hornisova On Thu, Jan 15, 2015 at 5:54 PM, Marco Atzeri wrote: > > > On 1/15/2015 5:39 PM, Klara Hornisova wrote: > >> I have installed OpenMPI 1.6.5 under cygwin. When trying test example >> >> $mpirun hello >> > > current cygwin package is 1.8.4-1, coul
