Re: Nutritious Rice for the World - 30 days left of new work

Thanks! This is turning into a real nail biter!! Will I make it to Sapphire? It's going to be a close one and I think I'm going to need those clean up units!


Don't worry...
As other people get their next Badge they will quite Rice and those 30 days will become 34-35 for the fewer people who will be still behind a little bit.
So, be positive about it. :-)

Re: Nutritious Rice for the World - 30 days left of new work

Take all your system(s) and multiply days short*24 hours*system efficiency*cores/7 hours and you'll know how many to crunch. Needing 12.32 days here for next level... started planning in October ;>)


I get about 3.65 days/24 hours from 4 CPUs (2 machines). When I work it out I'll be short by about 8 days. I'll increase my buffer towards the end to try to catch the shortfall that way, but I may be stuck needing a few cleanup units... It's part of the fun! I started crunching rice exclusively in October also, my plan has just missed though! crying

Damir1978, thanks for the positive message, but it is only a bit of fun wink

Don't forget the HyperThreading multiplier!

Re: Nutritious Rice for the World - 30 days left of new work

Hyperthreading by some efficiency analysis causes effective negative production [See Ingleside post testing with I7]. It's good for clocking loads of time. Mind you that might be on a science by science basis different as will it likely be varying when mixing different sciences. Someone posted few days ago to have switched off HT and saw dramatic improvement on run times for the DDDT2 A Type.

Re: Nutritious Rice for the World - 30 days left of new work

Yeah, I don't have it on any machines myself. But it does give you twice the time per core.

Re: Nutritious Rice for the World - 30 days left of new work

But I see where I screwed up. You were finding the number of WU's to get, whereas I was thinking in terms of how much time per day you were logging, and then extrapolating from that to how long it would take.

Re: Nutritious Rice for the World - 30 days left of new work

Maybe dramatic improvement on run times for the DDDT2 A Type was caused by some RAM issues.
8 wu multiply by size of one (180 MB (memory privete working set) or 680 MB VM size)- quite a big number. Or maybe something related to CPU cache.

Re: Nutritious Rice for the World - 30 days left of new work

The specific reference Sekerob mentions above caused the DDDT2 A WU to complete 7 hours faster than the original projection. The WU had run for approximately 36 hours with another projected 20 hours to completion. I turned off HT to validate the WU faster and the WU was completed in 49 hours, and not the projected 56 hours. I do not believe that 6gigs of RAM with Windows 7 64bit Professional was the issue.

Based upon my experience for NRW, when you turn off HT the granted WU credit should improve sharply on a per WU basis. However, your daily aggregate granted WU credits decreases as fewer WU's are returned. This situation is true for NRW, excellent granted credits per WU, but lower overall granted credits over time.

Re: Nutritious Rice for the World - 30 days left of new work

Hmm, a discussion of the efficiency and the benefit of running with HT off or on looks a litle strange in this thread...

... since in this particular thread, running with HT off is a big disadvantage, since with HT on a computer will use half the time to reach whatever Rice-badge someone is chasing. wink

Re: Nutritious Rice for the World - 30 days left of new work

Is March 25 (febr 23 +30 days) still about the end date of sending out the regular workunits?
