Hi,
by now we know of three programs - dirac, wrf, quantum espresso - that
all hang with openmpi-1.4.x (have not yet checked with openmpi-1.6).
All of these programs run to completion with the mpiexec commandline
argument: --mca btl_openib_flags 305
We now set this in the global configuration file
Ifeanyi,
I am usually the one that responds to checkpoint/restart questions,
but unfortunately I do not have time to look into this issue at the
moment (and probably won't for at least a few more months). There are
a few other developers that work on the checkpoint/restart
functionality that might
You are correct that the Open MPI project combined the efforts of a
few preexisting MPI implementations towards building a single,
extensible MPI implementation with the best features of the prior MPI
implementations. From the beginning of the project the Open MPI
developer community has desired to
As far as I know, OMPI combines the fault tolerant features in FT-MPI, LA-MPI
and LAM/MPI, is this statement still correct now? Or as you say, OMPI supports
checkpoint/restart(like in LAM/MPI) only? I don't know the details of
FT-MPI or LA-MPI, aren't they useful or necesarry?In fact, what I rea
