we are running the old pgi 6.2 stuff on our cluster.
Now I’ve installed the current version (7.0-7) which is working fine.
In the ne xt step I added the MPI stuff (also downloaded from pgi)
and installed as described in the readme.
Everything seems to be fine, I can compile and also compile
parallel code. But running this code with mpirun
is not working.
If I force local execution everything seems to be normal.
ssh is also working without any problems, also the old
taiga:~ # mpirun -np 4 mpihello
hydra.bgc-jena.mpg.de: Connection refused
p0_21213: p4_error: Child process exited while making connection to remote process on hydra: 0
p0_21213: (37.031250) net_send: could not write to fd=4, errno = 32
How can I figure out the reason for this behavior ?
