[Wien] K-point split for Scyld Beowulf cluster with diskless node

[Peter Blaha]

> Is there anybody know how to run Wien2K on a Scyld Beowulf cluster with diskless nodes? I would like run k-point split parallel script and run lapw1(c) for k-point to different diskless node.

>In this kind of cluster, execute a program is using: bpsh [node] command.

>For example lunch lapw1c: I used :  bpsh 0 lapw1c lapw1.def

During installation of WIEN2k using siteconfig, you simple should
specify   bpsh    (instead of   rsh  or  ssh)

The you have to find out which nodes are assigned to your job and write
the corresponding   .machines file on the "fly" as first step of your job
(see faq page at www.wien2k.at)
