Dear Mr. Toyohisa,

thank you very much for your fast answer. I would like to send you 
some more details on our configuration:

We have one machine configured withe RedHat 7.2 and Score 5.0.1, 
called frontend.cluster.domain, which is connected only with 
Ethernet to the compute hosts. 
( see #"define MSGBSERV        
msgbserv=(frontend.cluster.domain:8764)" in scorehosts.db. The 
compute-hosts comp4, comp5, comp6 and comp7 are connected via 
ethernet and myrinet2k.

We have the following configuration files in /opt/score/etc:
============================================================================================
[root ＠ frontend etc]# more pm-myrinet.conf

We have an 8-port myrinet2k switch and the 4 nodes auf connected to 
the first 4 ports. We have also tried other ports without success.

Thank you very much for you help

With kind regards,
