@karabaja4: I think it uses ssh heavily in the course of “delegating” processes and communicating with them. Take a look at ps when running some program via mpirun, you'll find a bunch of ssh sessions with stdout redirected to originating host. Of course this is only a simple observation and the purpose of ssh may be different, but… I think it's quite reasonable to assume it is as described.

For some reason this package needs openssh package, otherwise even the simplest multiprocess tasks executed with mpiexec give segmentation fault.

@kkb110 That is a bug with the BLACS build system which the blacs-mpi package should work around. $ /opt/mpich2/bin/mpicc -show gcc -Wl,--hash-style=gnu -Wl,--as-needed -I/opt/mpich2/include -L/opt/mpich2/lib -lmpich -lopa -lmpl -lpthread -lrt

I think compiling blacs-mpi https://aur.archlinux.org/packages.php?ID=23035 fails because of this. gfortran -lpthread -o /tmp/yaourt-tmp-kkb110/aur-blacs-mpi/src/BLACS/TESTING/EXE/xFbtest_MPI-LINUX-0 blacstest.o btprim_MPI.o tools.o -L/tmp/yaourt-tmp-kkb110/aur-blacs-mpi/src/BLACS/LIB -lblacsf77 -lblacs -lblacsf77 -Wl,-rpath,/opt/mpich2/lib/ -L/opt/mpich2/lib/ -lmpich -lssl -luuid -lpthread -lrt -ldl -lnsl -lrt /opt/mpich2/lib//libmpich.so: undefined reference to `MPL_trfree' /opt/mpich2/lib//libmpich.so: undefined reference to `MPL_env2str' ... ...

@ram http://trac.mcs.anl.gov/projects/mpich2/ticket/1150 You can edit the PKGBUILD to use MPD if you want the -gdb option, but Hydra is a better process manager in many ways.

ram commented on 2011-08-26 13:53 (UTC)

I miss the -gdb flag. Is it removed for some reason?

jedbrown commented on 2011-06-19 14:01 (UTC)

This update removes support for the MPD and gforker process managers since Hydra is plenty stable these days.
