Just what I was looking for. At home, I'll have two computers while at work I've got a dual-CPU and a bunch of singles...at night! Found the Lightning download at corel.com. I'll search for docn. I've had good experiences with parallel-processing matrix solvers (same computer, across LAN) so was hoping that Bryce had something similar. Thanks for the reference to the earlier posting with the instructions. When I get it up, I'll let you know.
