Re: [OMPI users] Can't run with more than two nodes in the hostfile

What I mean with "another mpi process". I have 4 nodes where there is process that use mpi and where initiated using mpirun from the control node already running when I run the command against any of those nodes it execute but when I do it against any other node it fails if no_tree_spawn flag

[OMPI users] Can't run with more than two nodes in the hostfile

I'm trying to update to openMPI 1.8.1 thru ssh and Myrinet running a command as /opt/openmpi/bin/mpirun --verbose --mca mtl mx --mca pml cm -hostfile hostfile -np 16 when the hostfile contain only two nodes as host1 slots=8 max-slots=8 host2 slots=8 max-slots=8 it runs perfectly but when the

process test is always running 1 process by node. the following test pingpong, pingping, sendrecv, exchange presents a strong drop in performance with the 64k packet size. any idea where I should look for the cause. Ricardo On Fri, Mar 20, 2009 at 7:32 PM, Ricardo Fernández-Perea < rfernande

Hello, I am running DL_POLY in various Xserver 8 processor with a myrinet network.using mx-1.2.7 While I keep in the same node the process scales reasonably well but in the moment I hit the network ... I will like to try to maximize the mx network before trying to touch the program code. Is the

In the same machine the same job takes a lot more time while using XGrid than while using any other method even all the orted run in the same node when using Xgrid it use tcp instead of sm is that expected or do I have a problem. Ricardo
