Glen,
Thanks for the spending time benchmarking OpenMPI and for sending us the
feedback. We know we have some issues on the 1.0.2 version, more precisely
with the collective communications. We just look inside the CMAQ code, and
there are a lot of reduce and Allreduce. As i

Thank you Brian Barrett and Brian Granger. I downloaded and installed a new
version of gfortran from http://gcc.gnu.org/wiki/GFortranBinaries and the
install went without a problem. I had gfortran installed before from Fink.

mpirun (v1.0.1) sets the umask to 0, and hence creates world-writable
output files. Interestingly, adding the -d option to mpirun makes this
problem go away. To reproduce:
mpirun -np 1 --hostfile ./hostfile --mca pls_rsh_agent ssh ./a.out
where a.out is compiled from:

Dear Galen,
It actually turns out that there is a problem not only with
MPI_Alltoall_Isend_Irecv, but also with another related operation
insyncol_MPI_Alltoallv-nodes-long-SM.ski (this what seems to be holding
down the FFTs, I checked the source code, and it uses alltoallv):

mlistus,
Thank you for your question. The integration of fault tolerant
techniques into Open MPI is under active development at the moment.
As the site notes, we are scheduled to incorporate many forms of
fault tolerance into Open MPI which were previously supported by our
core projects,
hello list,
i'd like to know about the state of fault-tolerance in
open-mpi. it's said on the site that ompi takes
features from ft-mpi and la-mpi (among others), but i
couldn't find any reference on the site, nor during my
superficial search in the sources.
so, is ft implemented or en route?
thank
