CCL: File system for running ORCA in parallel

["John McKelvey" <jmmckel|-|gmail.com>]

 Folks,

ORCA apparently does not run in parallel using NFS.  Has
 anyone run ORCA in parallel on an SMP box, and what file system was
 used?

I'm assuming the problem with NFS might be file locking. 
 One question might be if NFS-V4 would be satisfactory since file locking is
 supposed to better..  Anyone try this?
 
Best regards,
