[OMPI users] configure/library question

2013-07-19 Thread Hodgess, Erin
Hello all! I just downloaded the MPICH 3.0.4 tar.gz Then I used tar xfvz tar-3.0.4.tar.gz ./configure make make install Now I'm trying to compile someone else's program and it can't find libmpi or libmpich.a I did find libmpich.a, but no libmpi. Does this sound familiar, please? Thanks for a

Probably a lot more familiar to the folks on the MPICH mailing list - this is the mailing list for Open MPI :-) On Jul 19, 2013, at 12:03 PM, "Hodgess, Erin" wrote: > Hello all! > > I just downloaded the MPICH 3.0.4 tar.gz > > Then I used > tar xfvz tar-3.0.4.tar.gz > ./configure > make > ma

[OMPI users] check point restart

2013-07-19 Thread Erik Nelson
I run mpi on an NSF computer. One of the conditions of use is that jobs are limited to 24 hr duration to provide democratic allotment to its users. A long program can require many restarts, so it becomes necessary to store the state of the program in memory, print it, recompile, and and read the s

I know that in the past it has been supported via toolkits like BLCR, but I don't know the current level of support, to be honest. I think I heard somewhere that the checkpoint/restart support in OpenMPI was going away in some fashion. In any case, if you have the ability to set up application-aw

I just upgraded the OS on one of my workstations from Fedora 17 to 18 and now I can't run even the simplest MPI programs. I filed a bug report with Fedora's bug tracker : https://bugzilla.redhat.com/show_bug.cgi?id=986409 My simple program is attached as mpi_simple.c mpicc works : mpicc -g -

Are you sure you're using the same version of OMPI on this new OS? They typically distribute one in your default path, so I'd check to ensure that you really are using the version you think. On Jul 19, 2013, at 12:49 PM, "Kevin H. Hobbs" wrote: > I just upgraded the OS on one of my workstatio

Whoever designed the application you're trying to use to work only with LIBS="-lmpi" indicates poor software engineering and a low-quality application. You can install or uninstall whatever you like but it is incorrect to think that MPICH is broken because it does not provide libmpi.{a,so}. In th

Not offhand. The error you're seeing *typically* indicates that you've got a mismatch of OMPI version somewhere. Are you running on multiple machines with different Open MPI versions, perchance? If you're running only on a single machine, try completely uninstalling the Open MPI package, re-i
