Re: [OMPI users] Open MPI 1.8.1: "make all" error: symbol `Lhwloc1' is already defined

Dear Jeff, These new versions of the tgz files replace the previous ones: I had used an old outdated session environment. However, the configuration and installation was OK again in each case. Sorry for the noise caused by the previous tgz files. Regards, Jorge. - Mensaje original - >

Re: [OMPI users] GCC 4.9 and MPI_F08?

@#$%@#$%#@$% I was very confused by this bug report, because in my mind, a) this functionality is on the SVN trunk, and b) we had moved the gcc functionality to the v1.8 branch long ago. I just checked the SVN/Trac records: 1. I'm right: this functionality *is* on the trunk. If you build the

(please keep the users list CC'ed) We talked about this on the weekly engineering call today. Ralph has an idea what is happening -- I need to do a little investigation today and file a bug. I'll make sure you're CC'ed on the bug ticket. On Aug 12, 2014, at 12:27 PM, Timur Ismagilov

Re: [OMPI users] GCC 4.9 and MPI_F08?

It should be in the 1.8.2rc tarball (i.e., to be included in the soon-to-be-released 1.8.2). Want to give it a whirl before release to let us know if it works for you? http://www.open-mpi.org/software/ompi/v1.8/ On Aug 12, 2014, at 11:44 AM, Daniels, Marcus G wrote:

Hi, Looks like there is not the check yet for "GCC$ ATTRIBUTES NO_ARG_CHECK" -- a prerequisite for activating mpi_f08. Could it be added? https://bitbucket.org/jsquyres/mpi3-fortran/commits/243ffae9f63ffc8fcdfdc604796ef290963ea1c4 Marcus

Re: [OMPI users] Multiple runs interaction

You can improve performance by using --bind-to socket or --bind-to numa as this will keep the process inside the same memory region. You can also help separate the jobs by using the --cpuset to tell each job which cpus it should use - we'll stay within that envelope. On Tue, Aug 12, 2014 at

Brilliant, this works! However I’ve to say that it seems that it seems that code becomes slightly less performing. Is there a way to instruct mpirun on which core to use, and maybe create this map automatically with grid engine? Thanks in advance Antonio On 12 Aug 2014, at 14:10, Jeff

Re: [OMPI users] Multiple runs interaction

The quick and dirty answer is that in the v1.8 series, Open MPI started binding MPI processes to cores by default. When you run 2 independent jobs on the same machine in the way in which you described, the two jobs won't have knowledge of each other, and therefore they will both starting

Re: [OMPI users] ORTE daemon has unexpectedly failed after launch

Are you running any kind of firewall on the node where mpirun is invoked? Open MPI needs to be able to use arbitrary TCP ports between the servers on which it runs. This second mail seems to imply a bug in OMPI's oob_tcp_if_include param handling, however -- it's supposed to be able to handle

Lenny -- Since this is about the development trunk, how about sending these kinds of mails to the de...@open-mpi.org list? Not all the OMPI developers are on the user's list, and this very definitely is not a user-level question. On Aug 12, 2014, at 6:12 AM, Lenny Verkhovsky
