timeout unit of measure

I've read the equations for timeout and final deadline, and this may be a stupid question, but is that in hours, days, or what? Hours would make the most sense to me, but I'd just like to be sure.

Deadlines are specified in days.

Welcome to the Forum ;)

Taken literally, that would mean my computer would have 20 * 4 + 2 days to complete the WU's I've been assigned lately. Isn't that way too long? I interpreted my timeout as 20 * 4 hours + 48 for two days. That would give me just under five days to complete the WU's I've been assigned, which seems much more reasonable to me. So which interpretation is correct? By the way, in the deadline equation, 30 * max(numOfDays + 2.18), max(.........) is the max of what, exactly?

Different client have different timeouts. The uni-processor has the longest of all the clients. Right now my uni has a deadline of 59days 18 hours and 44 mins, it will be done in 2days 18hours and 14 mins.

GPU deadlines are fast usually a few days
SMP is the same as the gpu with fast turn around.
PS3 not sure on them.

I hope this helps.

Ah, I see what you mean. The FAQ (and the formula) explains how they reach the timeout/ deadline timelines posted on the project summary page (http://fah-web.stanford.edu/psummary.html). For e.g., if Project X's WU takes 1 day to complete on the benchmark machine, then the preferred deadline = 20 * (1) + 2 = 22 and the final deadline = max(30 * (1) +2, 10) = 32.

These calculations aren't of much use to us; the calculated values posted in psummary are all that we want. And as tbk-aracthebold said, different classes of WU have different deadline periods (SMP and GPU projects have tighter deadlines, possibly implying that different formulae are used).

The Points FAQ is a good read, and has links to the benchmarking info for each of the clients.

Aha! It's all starting to make sense now. Thank you for clearing so much of this up. You know, I started dabbling in this project a few years ago, but I never really took the time to start studying it until now.
