At last, the new machine is now doing production work and I've run almost 24 hours so far. First, it's running a bit slower than anticipated, about 13.5 model years per day. I'm not sure what's causing the slower speeds, but it's still an acceptable speed considering my original estimate was only 7 model years per day.
Temperature remains a worry for me. The CPU temps seemed reasonable, but the RAM temps seemed rather high for long-term processing. So, I ordered some fans to cool the RAM boards.
Tomorrow, I'll take a look at the output and start planning a possible Cocoa front-end for running the model.
