No it would not! Back in '94 I ported dmake to FreeBSD and built just about every numerics package out there on a 4 CPU cluster. Worked fine, but not much in overall speedup, because... tadum! Where do you get the source files, and how do you get the objs back :-) Not low latency, eh? F-Enet then, G-Enet now :) Nowadays, you'd want to "globus ify" things, rather than use use PVM. But critically, speedup would only happen if jobs were allocated at a higher level than they are now. Now for building something like a full version of TAO, why that might work. But even then, a factor of 2x is unlikely until the dependencies are factored out at the directory level.
