And  it works! Mlucas is running, using almost 100% CPU. I no doubt have some learning ahead about how to make this process reliable and about how to properly submit any results that may emerge  but I thank you for getting me going! What a great project!

Glad to hear it  if you would be so kind as to paste the first few checkpoint summary lines from the p[exponent].stat file and maybe provide the salient stats about your system, I'd appreciate it.
We are hard at work on the next rev of the code, which will include automated primenetbased assignment/results management, so hopefully the manual method will soon be a relic of the past. Have Fun, Ernst

Thanks, smoky 
0.19 sec/iter for a 1664K FFT @ 875 MHz translates to a similar percycle throughput as Prime95's optimized SSE2 assembly code gets on a Core 2 processor  not bad for highlevel compiled code. Too bad the PARISCs aren't available n 3GHz+ models, eh? But  we do what we can, eh? Should be a fine platform for doublechecking. cheers, E
