I've been getting weird estimated times for the last couple of days, resulting in my downloaded WUs running in high priority mode. My latest WU has a 163 hour estimate. Is this okay or what?

Though I didn't check it yet, I think the estimates were way off again. I got one that was estimated to take over 80 hours but finished in 3 1/2. You could change your DCF to get rid of the panic mode. I built a calculator in VB express (.net 2.0) some time ago to easily calculate a better DCF. PM me your email address if you'd like to try it and I'll send it to you (or anyone else who wants it).

I think it is more of a nuisance than anything else. Probably just best to let BOINC take care of it at first until the times are estimated better. Fortunately, BOINC only downloads a few at a time and crunches those right away, so it could be a lot worse.

The workunits are acting strange still. many of the input files are deleting for reasons still unclear. I have monkeyed arround with the leng of some to make batch of them execute quicker than usual.

Gerry, adjusting the DCF is really simple (you can do it in the client_state.xml file), not worth the annoyance imho. The DCF skyrockets upwards when there are wrong estimates, but only are automatically adjusted downwards very slowly. The DCF for DD on one of my computers had gone up to 99. I adjusted it downwards to 4 or so and now the estimates look normal again.

And to Jack, the deadlines of 1 day can also cause panic mode. Wu's of other projects can error out due to that because of too many restarts and in the end you gain nothing as the LTD will stop downloading work for this project after a while.

Anyone have an idea how long these WUs are running? I have one now that is due tomorrow that is now through 9.5 hours, and I don't think it will finish on time. I hope it completes in less than about 25 hours.

This is how I am no calculating these values for estimates and deadlines. I think now that I fixed the extension value, it should start to make sense again.

$end=substr($file, rindex($file, "_-_")+3, rindex($file, "_bt_") - rindex($file, "_-_") - 3);
#$end = $start + $steps;
print "End: ".$end."\n";
$steps = $end - $start;
print "Steps: ".$steps."\n";
$extend = ($steps) * 0.002;
print "Extend ps: ".$extend."\n";
$half_extend = $extend * 0.5;
$nstart = $start + $steps;
$nend = $end + $steps;

$rsc_fpops_est = ($steps * 319500000);
$rsc_fpops_bound = ($rsc_fpops_est * 100);
$rsc_memory_bound = 500000000;
$delay_bound = (172800 + $steps * 10);
