The Green Machine
How well are they doing, I am kind of down on mine and never got a chance to run mine.
Did they complete in less than 100 Hours?
Sorry for the late response, but by the time of posting, the 980's had not yet began crunch the Genefer's.
Now they have a couple of hours, enough to read a fairly estimate.
For those who have not ran any PrimeGrid Genefers, a small update.
There are two types of Genefer's, one small, and one big one.
The small one, GFN-Short, can be ran on both CPU or GPU.
Recent average CPU time according to PrimeGrid 119:23 hrs.
GPU time 13:06
Then there is the Genefer I run.
The Genefer World Record GFN-WR.
This is a "Big Guy" and can only be ran trough GPU.
Recent average GPU time according to PrimeGrid is 128:12 hrs.
The concept for this is that if you find a prime number trough this search, it's gonna be FrontPage stuff.
They beleive they may hide some of the worlds biggest prime numbers so, this is a hunt for the biggest Fish in the pond.
So, for what it takes...
I have served this WU's to a small variety of GPU's. None are done yet, so I'll just give you the estimates.
My BOINC Version is 7.4.36 (x64) so the estimates should be fairly accurate.
First the EVGA 980SC:
#1. Elapsed 12:12hrs Time remaining 76:10hrs
#2. Elapsed 12:08hrs Time remaining 76:27hrs
Plain GTX760
#1. Elapsed 23:13hrs Time remaining 131:00
#2. Elapsed 23:13hrs Time remaining 115:00
GTX660Ti
Elapsed 23:58hrs Time remaining 113:00
EVGA 780Ti SC
Elapsed 23:58hrs Time remaining 30:52
EVGA 780Ti KPE (Kingpin Edition)
Elapsed 11:30hrs Time remaining 60hrs.
I had some problems With the Kingpin's.
The GFN-WR is very sensitive to overclocking, and they kept returning the GFN's With errors.
I reconed it was due to the Stock OC, so I reduced the Power target via Precision X to 85%.
After this, the remaining GFN seemed to stick.
I'll let it be for a little while before I engage the second Kingpin.
And for those who Wonder, the GFN-WR grant 50% long job bonus, so if you finish a GFN-WR they pay prox 650K.
