To whom this may concern,
I am receiving the following errors when attempting to run Gromacs in
parallel:
Making 1D domain decomposition 4 x 1 x 1
p2_21562: p4_error: Timeout in establishing connection to remote process: 0
p2_21562: (302.964844) net_send: could not write to fd=5, errno = 32
where I am using mpich 1.2.7 for 64 bit processors. From what I can find,
it seems as if this is a mpich issue and not an issue of Gromacs. Has
anyone else encountered such a problem? Also, does anyone have any
suggestions for a solution?
Indeed, this is not a problem intrinsic to GROMACS. I'm not aware of
problems with particular MPI libraries, but you might try compiling
GROMACS with another such library. Whoever configured this machine
should probably look into the problem.
