-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I hope I'll be able to join as well (though I'm technically on vacation). I think the proposed changes for ticket 383 doesn't reflect what we had in mind (or at least what I had in mind ;-)), and we should discuss this very carefully - ideally with Martin as this affects all tools which will support MPI_T. My idea was, and maybe that wasn't clear from the discussions we had, that on heterogeneous systems variables with the same name have the same semantics, not only the processes in the same MPI_COMM_WORLD. An example is the DEEP system (www.deep-project.eu) where we'll have a cluster of Xeons and an attached cluster of Xeon Phis (a.k.a. booster) , both running MPI and processes on the cluster should offload kernels to the booster via MPI_COMM_SPAWN. Thus, the processes on the cluster and those on the booster are connected. Now I would like to ensure that variables with the same name are required to have the same semantics across all processes, be it cluster or booster, e.g. the eager limit or total network packages sent (although there should be counters for the different network interfaces). With the proposed changes to the ticket, this is no longer guaranteed. I think classifying the events in the library by MPI library versions prevents that entirely, because in the case above, events with the same name and semantics exist on the Xeons and the Xeon Phis, which are classified differently. If we go with the proposed addition of checking the MPI library version string, my concern is that MPI implementations would opt for the easy way and simply provide different version strings for the libraries, which in the end would result in the same mess. My understanding is that MPI versions from different vendors can't easily connect as there is no MPI ABI, so that the issue with two independent libraries shouldn't be a major problem. - -Michael On 09/30/2014 11:01 AM, Schulz, Martin wrote: > Yes, the notes are on the Wiki, but feel free to add if I forgot > something. > > Sorry, I can’t make it on Thursday, > > Martin > > > > On 9/29/14, 6:34 PM, "Kathryn Mohror" <kathryn(a)llnl.gov> wrote: > >> Hi Marc-Andre, >> >> Great!

Hi Jim, I just had a discussion with Michael Knobloch of our team and he raised an issue that I had not in mind in Kobe. He will send a separate email to elaborate on this to the tools ML (and I hope with you in CC). Could you motivate again, why you wanted the library version string to identify counter domains?

Cram v1.0
by Todd Gamblin 23 Sep '14

23 Sep '14

Hi all, I¹ve just released version 1.0 of Cram, a new PMPI tool that members of this list may be interested in: https://github.com/scalability-llnl/cram Cram lets you run many small MPI jobs within a single, large MPI job by splitting MPI_COMM_WORLD up into many small communicators. This is not unprecedented; tools have done this for a while. However, I think it¹s the first tool that actually makes it easy. Cram has command-line and python scripting interfaces that allow you to create "cram files². Each cram file is packed with an ensemble of jobs, where a job comprises: - process count - working directory - command line arguments - environment variables When you link against libcram (or libfcram) and launch your job with a particular cram file, Cram will split COMM_WORLD and run all the jobs in the cram file independently. And yes, it handles args for Fortran, at least on BG/Q. If people want that capability on some other platform, let me know. Cram is NOT a job scheduler; it is a simple, lightweight layer between your jobs and the MPI runtime. There are no plans to support things like job queues or emulating a resource manager inside an MPI job. Cram was created to allow automated test suites to pack more jobs into a BG/Q partition, and to run large ensembles on systems where the scheduler won¹t scale. On BG/Q, for example, SLURM can run ~20,000 simultaneous jobs before it falls over. With Cram we¹ve been able to run 1.5 million MPI jobs at once, i.e. one job per core on all of Sequoia. This has been useful so far for running large ensembles of uncertainty quantification jobs. For full documentation, see the github page above. Thanks, -Todd
