Re: Forked Processes Won't Migrate, Perl & ForkManager

Thanks Daniel for your reply.

I tried your script and it indeed does spread the work among the 
available nodes.  (I got the highest load reading I've ever seen using 
it - very cool. :) )

Using this method of forking processes, would I be better served 
re-writing the script (again) to fork a separate process for each record 
and pass the record in as a parameter or by including a call to the 
processing routine in where you have the math functions?

Are there any special commands I should not use that would possibly 
prevent the migration of the spawned processes?
