Re: [OMPI users] How to set a process on a host but not bound to any core

It works!! Thanks a lot for the help!! -- Just add "-mca rmaps seq" to your command line, then. The mapper will take your hostfile (no rankfile) and map each proc sequentially to the listed nodes. You ne

Just add "-mca rmaps seq" to your command line, then. The mapper will take your hostfile (no rankfile) and map each proc sequentially to the listed nodes. You need to list each node once for each proc - something like this: nodeA nodeB nodeB nodeC nodeA nodeC ... would produce your described pa

What version of OMPI are you using? We have a "seq" mapper that does what you want, but the precise cmd line option for directing to use it depends a bit on the version. On Apr 9, 2014, at 9:22 AM, Gan, Qi PW wrote: > Hi, > > I have a problem when setting the processes of a parallel job wi

[OMPI users] How to set a process on a host but not bound to any core

Hi, I have a problem when setting the processes of a parallel job with specified order. Suppose a job with 6 processes (rank0 to rank5) needs to run on 3 hosts (A, B, C) with following order: Rank0 -- A Rank1 -- B Rank2 -- B Rank3 -- C Rank4 -- A
