On some of my larger problems ,
my program stalls and does not continue
(50 or more nodes, 'long' runs >5 hours). My program is set up as a
master-worker
and it seems that the master gets stuck in a write to stdout see gdb
backtrace below (It took all day
to get there on 50 nodes). the functi
Today I ran into the same problem as Warner Yuen (see thread below),
openmpi does not compile with icc and fails with an error where
libtool ask for --tag. The error is macosx specific.
It occurs in the compile for xgrid
in
openmpi-1.1/orte/mca/pls/xgrid
the Makefile fails; xgrid uses some
Dear Andy,
you wrote that with openmpi:
avierstr@muscorum:~> mpiexec --hostfile hostfile -np 1 migrate-n
it does not work, but with lam-mpi
avierstr@muscorum:~/thomas> mpiexec -np 2 migrate-n
you started openmpi on only _one_ node, migrate needs at least _two_
nodes to run
(as you did
am for simulation purposes, but
that would not be a typical use of the program that can distribute
multiple genetic loci on multiple nodes and only having
the master handling input and output (when compiled using configure;
make mpis or configure;make mpi)
