Hello All, I previously suggested to Jacob a setup where only one proc
would have a write handle and all of the other processes would be in
read-only mode.  I am not sure that this would work.

Francesc, Antonio, Josh, etc or anyone else, how would you solve this
problem where you may want many processors to query the file, while
something else may be writing to it?  I defer to people with
more experience...  Thanks for your help!

Be Well
Anthony
