mpd on Scyld Beowulf Cluster compute nodes<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>Hello,</DIV>
<DIV> </DIV>
<DIV>My system is an AMD Opteron cluster running Penguin Computing Scyld
Linux release 30cz, with a full linux on master node but thin kernel on
compute nodes. Communication mostly thru bproc. rshd is also enabled on
compute nodes for a separate mpich1. </DIV>
<DIV> </DIV>
<DIV>After installation of MPICH2, no problem starting mpd on master node. But
launching mpd always exit silently, using bpsh, or rsh to compute node then
start it. PYTHONHOME has set properly to import the required libs. Files
resident on master node are recognized by same path in compute nodes
via NFS. Clueless what else needed for such a system to bring
up mpd. </DIV>
<DIV> </DIV>
<DIV>Any advices are appreciated. Thank you in advance.</DIV>
