You also mentioned in your post that the permissions for the .compute
partition were 766; I believe this means that you indeed do not have
the permissions to run a job here. If you did, however, you would tie
up the entire .compute partition so that no one else could run there!

What you probably want to do is make a subpartition with mkpart and 
then start up the pvmd's in your partition. The following may hopefully
work:

% mkpart -sz 6 pvm_stuff
% pvmd -sz 6 -pn pvm_stuff
  (the second -sz 6 is probably unnecessary)

Since you, not root, would be the owner of this subpartition, you could
run anything you want here without permission problems.

Good luck! PVM works pretty well on the Paragon, but it can be right
confusing at times.
