Oh no, by using two procs:
findActiveDevices Error We found no active IB device ports findActiveDevices Error We found no active IB device ports -------------------------------------------------------------------------- At least one pair of MPI processes are unable to reach each other for MPI communications. This means that no Open MPI device has indicated that it can be used to communicate between these processes. This is an error; Open MPI requires that all MPI processes be able to reach each other. This error can sometimes be the result of forgetting to specify the "self" BTL. Process 1 ([[12380,1],0]) is on host: openpower Process 2 ([[12380,1],1]) is on host: openpower BTLs attempted: self Your MPI job is now going to abort; sorry. -------------------------------------------------------------------------- *** An error occurred in MPI_Init *** on a NULL communicator *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort, *** and potentially your MPI job) *** An error occurred in MPI_Init *** on a NULL communicator *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort, *** and potentially your MPI job) -------------------------------------------------------------------------- MPI_INIT has failed because at least one MPI process is unreachable from another. This *usually* means that an underlying communication plugin -- such as a BTL or an MTL -- has either not loaded or not allowed itself to be used. Your MPI job will now abort. You may wish to try to narrow down the problem; * Check the output of ompi_info to see which BTL/MTL plugins are available. * Run your application with MPI_THREAD_SINGLE. * Set the MCA parameter btl_base_verbose to 100 (or mtl_base_verbose, if using MTL-based communications) to see exactly which communication plugins were considered and/or discarded. -------------------------------------------------------------------------- [openpower:88867] 1 more process has sent help message help-mca-bml-r2.txt / unreachable proc [openpower:88867] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages [openpower:88867] 1 more process has sent help message help-mpi-runtime.txt / mpi_init:startup:pml-add-procs-fail 2017-05-19 9:22 GMT+02:00 Gabriele Fatigati <g.fatig...@cineca.it>: > Hi GIlles, > > using your command with one MPI procs I get: > > findActiveDevices Error > We found no active IB device ports > Hello world from rank 0 out of 1 processors > > So it seems to work apart the error message. > > > 2017-05-19 9:10 GMT+02:00 Gilles Gouaillardet <gil...@rist.or.jp>: > >> Gabriele, >> >> >> so it seems pml/pami assumes there is an infiniband card available (!) >> >> i guess IBM folks will comment on that shortly. >> >> >> meanwhile, you do not need pami since you are running on a single node >> >> mpirun --mca pml ^pami ... >> >> should do the trick >> >> (if it does not work, can run and post the logs) >> >> mpirun --mca pml ^pami --mca pml_base_verbose 100 ... >> >> >> Cheers, >> >> >> Gilles >> >> >> On 5/19/2017 4:01 PM, Gabriele Fatigati wrote: >> >>> Hi John, >>> Infiniband is not used, there is a single node on this machine. >>> >>> 2017-05-19 8:50 GMT+02:00 John Hearns via users < >>> users@lists.open-mpi.org <mailto:users@lists.open-mpi.org>>: >>> >>> Gabriele, pleae run 'ibv_devinfo' >>> It looks to me like you may have the physical interface cards in >>> these systems, but you do not have the correct drivers or >>> libraries loaded. >>> >>> I have had similar messages when using Infiniband on x86 systems - >>> which did not have libibverbs installed. >>> >>> >>> On 19 May 2017 at 08:41, Gabriele Fatigati <g.fatig...@cineca.it >>> <mailto:g.fatig...@cineca.it>> wrote: >>> >>> Hi Gilles, using your command: >>> >>> [openpower:88536] mca: base: components_register: registering >>> framework pml components >>> [openpower:88536] mca: base: components_register: found loaded >>> component pami >>> [openpower:88536] mca: base: components_register: component >>> pami register function successful >>> [openpower:88536] mca: base: components_open: opening pml >>> components >>> [openpower:88536] mca: base: components_open: found loaded >>> component pami >>> [openpower:88536] mca: base: components_open: component pami >>> open function successful >>> [openpower:88536] select: initializing pml component pami >>> findActiveDevices Error >>> We found no active IB device ports >>> [openpower:88536] select: init returned failure for component >>> pami >>> [openpower:88536] PML pami cannot be selected >>> ------------------------------------------------------------ >>> -------------- >>> No components were able to be opened in the pml framework. >>> >>> This typically means that either no components of this type were >>> installed, or none of the installed componnets can be loaded. >>> Sometimes this means that shared libraries required by these >>> components are unable to be found/loaded. >>> >>> Host: openpower >>> Framework: pml >>> ------------------------------------------------------------ >>> -------------- >>> >>> >>> 2017-05-19 7:03 GMT+02:00 Gilles Gouaillardet >>> <gil...@rist.or.jp <mailto:gil...@rist.or.jp>>: >>> >>> Gabriele, >>> >>> >>> pml/pami is here, at least according to ompi_info >>> >>> >>> can you update your mpirun command like this >>> >>> mpirun --mca pml_base_verbose 100 .. >>> >>> >>> and post the output ?
