I've got an AP 5.0 wu running that has time to completion as 450 hours on a Core 2 Quad Q6700. Is that normal? I've never noticed a SETI work unit that took that long to crunch.

No, it's because you've been running CUDA setiathome_enhanced work and the Duration Correction Factor is high. Crunch time wlll probably be a tenth or less of that estimate. Astropulse does take considerably longer than setiathome_enhanced though, even on hosts running both with CPU.

Thanks. I noticed after I posted that just under 4 hours in the WU is 12% complete so I thought there must be something like that going on,


The work unit finished with a compute error. Here's the message:

What happened and how do I stop it from happening again? This WU took up 21871.03 of processor time, I'd rather this didn't happen again.

This thread is to post errors and address concerns regarding the new Optimised AP v5.00 Astropulse application.

Please do not open new threads but post errors and commentary here.

Please, upgrade your optimized AP version to ap_5.00r69 !

Thanks!
