Any fast paths out of Category 3 purgatory
 
This is not a big deal but I figured I would ask anyway. I had a computer out of commission for 3 weeks after the DVD drive I had in in caught on fire. By the time I got a new case, cleaned the undamaged components, and tested everything thoroughly the exponents I had queued up had expired. I'm ok with spending 3 months crunching through 75 Cat 3 exponents, but since the CPU in this box can do one exponent every 37-38 hours it could be helping clear Cat 0/1 faster.

What kind of CPU is it? How many workers are being run? And how many days of of work are you keeping?

Basically you have to wait 6 months.

But you do raise an interesting point: the rules are such that an unknown machine is trusted much more quickly than a machine that had a previous good record.

It's a 22-core Xeon E5-2696v4. I've mentioned it before here: [url]http://mersenneforum.org/showthread.php?t=23196&page=2[/url]

One worker and queue 3 days of work.

The assignment rules for 0/1/2 say no expired exponents in the last 120 days. So hopefully that's true and it's 4 months instead of 6.

Yeah, 4 months. My bad.

Yeah, actually it was a Blu-ray burner, and it had a Ken Burns DVD in it at the time. I think it was just too much burn.

I'd suspect a badly seated power connector as the most probable cause.

You can still manually test any exponent using the [c]AdvancedTest[/c] feature. Just be sure to pick exponents that are far enough ahead of the wavefront so that you don't accidentally poach anyone's assignment.
