I need to be able to purge a PVFS filesystem based on the last time a file was 
accessed (rather than modified).  It appears that PVFS does not update atime.   
Is there a way to mount a PVFS filesystem so that it will update atime?   Or 
any other suggestions on how to remove files that have been accessed within X 
days?

The goal is to not purge files that might be used as input for many compute 
jobs but are not being modified.

Thank you in advance for your  help.
