[OMPI users] Circumvent --host or dynamically read host info?

Hi, I have a question regarding the --host(file) option of mpirun. Whenever I try to fork a process on another node using Spawn(), I get the following message: Verify that you have mapped the allocated resources properly using the --host specification. I understand this can be fixed by providing

[OMPI users] OpenMPI and Port Range

Hi all, Is there anyway to specify the ports that OpenMPI can use? I'm using a TCP/IP network in a closed environment, only certain ports can be used. Thanks, Si Hammond University of Warwick

Re: [OMPI users] Circumvent --host or dynamically read host info?

I take it you are running in an rsh/ssh environment (as opposed to a managed environment like SLURM)? I'm afraid that you have to tell us -all- of the nodes that will be utilized in your job at the beginning (i.e., to mpirun). This requirement is planned to be relaxed in a later version, but that

Re: [OMPI users] OpenMPI and Port Range

I have a patch for this, but I never felt a real need for it, so I never push it in the trunk. I'm not completely convinced that we need it, except in some really strange situations (read grid). Why do you need a port range ? For avoiding firewalls ? Thanks, george. On Aug 30, 2007,
