[OMPI users] Collective component priorities and sm

Dear OpenMPI experts I am confused about the role and values of priorities set to the OpenMPI collective components, and why the shared memory (sm) collective component disqualifies itself (apparently by default). I describe the problem, then ask a some questions, if you have the patience to

[OMPI users] Specifying slots in rankfile

Hi, I'd like mpirun to run tasks with specific ranks on specific hosts, but I don't want to provide any particular sockets/slots/cores. The following example uses just one host, but generally I'll use more. In my hostfile I just have: root@host01 slots=4 I was playing with my rankfile to achieve

Re: [OMPI users] Specifying slots in rankfile

I would recommend using the sequential mapper instead: mpirun -mca rmaps seq You can then just list your hosts in your hostfile, and we will put the ranks sequentially on those hosts. So you get something like this host01 <= rank0 host01 <= rank1 host02 <= rank2 host03 <= rank3 host01 <=

I would have to look at the code, but I suspect it doesn't handle "*". Could be upgraded to do so, but that would depend on the relevant developer to do so :-) On Jun 9, 2010, at 10:16 AM, Grzegorz Maj wrote: > Thanks a lot, it works fine for me. > But going back to my problems - is it some

Re: [OMPI users] mpi_iprobe not behaving as expect

I'll take a stab at this since I don't remember seeing any other replies. At least in the original code you sent out, you used Isend/sleep/Wait to send messages.  So, I'm guessing that part of the message is sent, Iprobe detects that a matching message is in-coming, and then the receiver goes

Hi Govind Besides what Ralph said, make sure your OpenMPI was built with Torque ("tm") support. Suggestion: Do: ompi_info --all | grep tm It should show lines like these: MCA ras: tm (MCA v2.0, API v2.0, Component v1.4.2) MCA plm: tm (MCA v2.0, API v2.0, Component v1.4.2) ... *** If your

Re: [OMPI users] Behaviour of MPI_Cancel when using 'large' messages

Yes, Open MPI does not implement cancels for sends. Cancels *could* be implemented in Open MPI, but no one has done so. There are three reasons why: 1. It can be really, really hard to implement cancels (lots of race conditions and corner cases involved). 2. Very, very few people ask for it

Hi Govind It may work with the suggestion I sent you, even with the OpenMPI with no Torque support that you have. However, since you have Torque installed on your cluster, it may be better to install OpenMPI from the source code tarball, so as to have full Torque support built in, which is much
