Re: [OMPI users] test for sctp on FreeBSD too narrow

Thank you! I'll put this on the trunk and the upcoming releases. This is too late for v1.6.2, but it can be in 1.6.3. On Sep 10, 2012, at 4:22 PM, Brooks Davis wrote: > The test for SCTP support in libc on FreeBSD only allows it to work on > FreeBSD 7 (or I suppose 70 :). That attached patch

[OMPI users] test for sctp on FreeBSD too narrow

The test for SCTP support in libc on FreeBSD only allows it to work on FreeBSD 7 (or I suppose 70 :). That attached patch expands the test to 7 though 19 which should be enough for a while. Hopefully by the time FreeBSD 19 is out everything will have sctp support in libc or have dropped it. :) --

Re: [OMPI users] Test OpenMPI on a cluster

It seems your OpenMPI installation is not PBS-aware. Either reinstall OpenMPI configured for PBS (and then you don't even need -np 10), or, as Constantinos says, find the PBS nodefile and pass that to mpirun. On Sat, 2010-01-30 at 18:45 -0800, Tim wrote: > Hi, > > I am learning MPI on a

Using direct can cause scaling issues as every process will open a socket to every other process in the job. You would at least have to ensure you have enough file descriptors available on every node. The most likely cause is either (a) a different OMPI version getting picked up on one of t

It sounds like perhaps IOF messages aren't getting relayed along the daemons. Note that the daemon on each node does have to be able to send TCP messages to all other nodes, not just mpirun. Couple of things you can do to check: 1. -mca routed direct - this will send all messages direct inst
