"...UNLIMITED number of clusters ranging in size from 5 to 64 CPUS..."

I devlop on a 32 CPU "development" cluster. I want to run the code on a 
256 CPU "production" cluster... Problem with Lahey, not a problem with 
the others. I'm restricted by their license.

I have a 48 CPU cluster where I'm using a Lahey compiler. Due to the 
data throughput requirements I need another 48 CPUs.... Problem with 
Lahey, not a problem with others. Similar to Microsoft Windows XP - I 
add stuff to my computer I have to revise my license...

Hopefully I'm wrong about their restrictive license...

John
