Keep in mind that my goal was to provide context. To make it clear, my personal thought is that the platform (BOINC) already has a system that the tech, knreed, is adjusting to keep work units from languishing too long. That is, the definition of a "reliable" machine which knreed already adjusted down from one that returns within 2.5 days to one that returns within 2 days.

So in the worst-case scenario where people are hogging a load of work units on their machines and not returning in a timely fashion, once those all time out they will get resent to reliable machines and be likely to get returned within that 36 hours proposed in the OP, especially if the definition was cut to 1.5 days. If that were to continue without further action that would mean you'd be adding a week for that initial timeout to occur for each generation which would be bad for getting ARP done sooner. However, knreed is also prioritizing older generations even for newly-generated work units if they're falling too far behind the head of the pack.

It is stated that they try to have 20% of work units sent out going to reliable machines. With aggressive tweaking of the aforementioned settings they could get that to, say, 80%. But then you would see a backlog appear again as slower machines would not qualify for any eligible work units. So I don't think they will have much interest in modifying points based on return time (if they even could) because they have tools already and have gone as aggressive as they desire at this point.

Hello Fellow Crunchers,
I got two points:
1. I very much doubt, whether the changes proposed would really speed up research, as the overal amount of operations needed to complete a workunit and a project does not change. There maybe less resends, but the number of calculations stays needed to complete a projects stays the same.
2. I fear, that owners of slow machines and cruchers just starting to contribute ("newbees") will be frustrated and bewildered, if they are "punished" for not contributing enough work power in a certain amount of time.

Personally, I would not request this features, but others, more powerful ones.....GPU...old topic....I know. Sorry about it, but I had to say it.

I will keep crunching 24/7, even if it is hot in my room.

Best whishes

I complete about 1 per day on my 3770 running Win 7. I do not recall having to wait for any significant amount of time to get another one. For me the supply has been quite dependable. I am running 7 MCM with 1 ARP on a 8 thread machine. I don't see any impact on normal use of the machine. I only have two in pending validation.
Cheers
