Hi,

thank's for your answer.

SGE 6.1. The port number is ok.

Within the cluster there is no firewall. There are no other applications 
running
accross the nodes. The setup works for MPICH1, and MPICH2 smpd, just with
Hydra are the problems. I also can not see any network problems.
The more mysterious, Hydra works fine on another cluster (with same OS 
and SGE).
Hmm.

yes, the tight integration works fine! (I'd be happy if it were the same 
with mvapich.)

I tried it out on the cluster where hydra performs:  it  works perfectly -
thank you.

Just the hydra problem on the other cluster remains and I don't have any
ideas why.
