Re: [OMPI users] MPI_Comm_spawn errors
Hi Joao, Unfortunately, spawn is broken on the development trunk right now. We are working on a major revamp of the runtime system which should fix these problems, but it is not ready yet. Sorry about that :( Tim Joao Vicente Lima wrote: Hi all, I'm getting errors with spawn in the situations: 1) spawn1.c - spawning 2 process on localhost, one by one, the error is: spawning ...

[OMPI users] openmpi/openib problems
Hi all, I'm having problems getting openmpi to work correctly using verbs on some systems. It's been working using openib for quite some time, but I need to get it working using verbs for some research I'm doing. Anyway all seems to be good on the openib side of things. ibv_devinfo and ibv_devices returns device information, and they are listed as active on each node. Also all hosts are visible to each other (ibhosts shows a full list). The problem I see with openmpi is I have the openib btl, but not the openib mpool, and when looking at the contents of ompi/mca/mpool/ I don't see openib there (sm and rdma are both listed and ompi_info shows they've been included in the build). Any help would be appreciated. Thanks, Jessie

[OMPI users] mpi.h macro naming
Thanks in advance if this is already fixed in a later release I've not caught up to, I'm at 1.2.3. Is there some subtle reason that ompi's mpi.h leaves the following macros both unguarded with an ifndef and un-prefixed with OMPI_ ? This produces considerable amounts of compiler whinage for other codes that include mpi.h. As always, extraneous whinage makes real errors harder to find. (And yes, those other codes also need *their* definitions of HAVE_LONG_LONG, etc properly protected). And of course who knows how the answer was defined for any given unprotected appearance of these macros? /* Define to 1 if the system has the type `long long'. */ #undef HAVE_LONG_LONG /* The size of a `bool', as computed by sizeof. */ #undef SIZEOF_BOOL /* The size of a `int', as computed by sizeof. */ #undef SIZEOF_INT If it's simply a matter of developer hours, I can post a patch somewhere to address this. It appears that of these, only sizeof_int affects more than a few source files. thanks, Ben Allan
[OMPI users] processes aborting on MPI_Finalize
This is probably some coding error on my part, but under some problem divisions I get processes aborting when I call MPI_Finalize(). Perhaps they are still waiting incorrectly to recived some message or something like that. Sometimes it seems to work. Is there a good way to get to the bottom of this error? output- 4 additional processes aborted (not shown) Sam Adams General Dynamics Information Technology Phone: 210.536.5945
Re: [OMPI users] Can't get OPENMPI to run parallel job with Myrinet/GM
Would you be able to send me the mpirun command and args that you use? how can I get more output to study? I added "--display-map -d -v " to my mpirun command, which gives more output, but not the reason for the failure.

Re: [OMPI users] Can't get OPENMPI to run parallel job with Myrinet/GM
Tom, Here is how I configured Open MPI. It's mostly the default configuration ... ../../ompi-trunk/configure --prefix=/nfs/home/bosilca/opt/unstable/fog/ fast --disable-debug --enable-picky --with-platform=optimized -- disable-mpi-cxx --disable-mpi-f90 --enable-mpi-f77 --disable-mpi- profiling --with-gm=/opt/gm -enable-visibility No specific arguments were required to run the tests. You can force the GM BTL by using "--mca btl gm,self" or "--mca btl gm,sm,self" if you need shared memory. george.
