I am running a pvm application on a cluster of 10 SGI-Indies which use AFS
for their main file systems. Kerberos is used to authenticate access to
the AFS file systems, with a token lifetime of 24 hours. Any job that runs
for longer than this ( eg. pvm demons .... ) dies when it next tries to
access a file on AFS.

I have looked at Rainer Toebbicke's ARC package
<http://wwwcn1.cern.ch/~rtb> to renew Kerberos tokens, but it looks as if
it would be a lot of work to interface it to PVM. Has anybody else come
across this problem or have a solution?
