Re: [OMPI users] openmpi-1.7.4a1r29646 with -hostfile option under Torque manager

Hmmm...okay, I understand the scenario. Must be something in the algo when it only has one node, so it shouldn't be too hard to track down. I'm off on travel for a few days, but will return to this when I get back. Sorry for delay - will try to look at this while I'm gone, but can't promise

Re: [OMPI users] openmpi-1.7.4a1r29646 with -hostfile option under Torque manager

Hi Ralph, sorry for confusing. We usually logon to "manage", which is our control node. >From manage, we submit job or enter a remote node such as node03 by torque interactive mode(qsub -I). At that time, instead of torque, I just did rsh to node03 from manage and ran myprog on the node. I

Re: [OMPI users] openmpi-1.7.4a1r29646 with -hostfile option under Torque manager

Hi Ralph, I tried again with -cpus-per-proc 2 as shown below. Here, I found that "-map-by socket:span" worked well. [mishima@node03 demos]$ mpirun -np 8 -report-bindings -cpus-per-proc 2 -map-by socket:span myprog [node03.cluster:10879] MCW rank 2 bound to socket 1[core 8[hwt 0]], socket

Hmmm...that's strange. I only have 2 sockets on my system, but let me poke around a bit and see what might be happening. On Dec 10, 2013, at 4:47 PM, tmish...@jcity.maeda.co.jp wrote: > > > Hi Ralph, > > Thanks. I didn't know the meaning of "socket:span". > > But it still causes the

Re: [OMPI users] openmpi-1.7.4a1r29646 with -hostfile option under Torque manager

Hi Ralph, Thanks. I didn't know the meaning of "socket:span". But it still causes the problem, which seems socket:span doesn't work. [mishima@manage demos]$ qsub -I -l nodes=node03:ppn=32 qsub: waiting for job 8265.manage.cluster to start qsub: job 8265.manage.cluster ready [mishima@node03

Re: [OMPI users] openmpi-1.7.4a1r29646 with -hostfile option under Torque manager

No, that is actually correct. We map a socket until full, then move to the next. What you want is --map-by socket:span On Dec 10, 2013, at 3:42 PM, tmish...@jcity.maeda.co.jp wrote: > > > Hi Ralph, > > I had a time to try your patch yesterday using openmpi-1.7.4a1r29646. > > It stopped the

Re: [OMPI users] openmpi-1.7.4a1r29646 with -hostfile option under Torque manager

Hi Ralph, I had a time to try your patch yesterday using openmpi-1.7.4a1r29646. It stopped the error but unfortunately "mapping by socket" itself didn't work well as shown bellow: [mishima@manage demos]$ qsub -I -l nodes=1:ppn=32 qsub: waiting for job 8260.manage.cluster to start qsub: job

Re: [OMPI users] configure: error: Could not run a simple Fortran program. Aborting.

Thanks Jeff, It turns out this was an issue with Homebrew (package manager for mac) and not related to open-mpi... If any Homebrew users have this issue in the future when installing open-mpi here's what happened: there were some non-Homebrewed 32-bit gfortran libraries floating around in the
