The Globus folks have some work that I saw described at CCGrid in Singapore
this year called Workspaces  which is basically deploying a Xen VM to
provide a known OS and application stack for grid jobs.
It has the added advantage that once the job is complete and results retrieved
then the VM can be destroyed and it is out of the way. They have separate
filesystems for the root, usr and other areas to make it possible to mix and
The driver behind this is the age old question of grid computing that if I can
submit a job and a meta-scheduler picks a random cluster, how can I know that
it will have the right environment for my application ?
