Khali, when I look at your task from this link, I see 14 threads (-oThreadsPerTest=14). When I look at your computer from this link, I see 213 tasks "In progress". That is too many.

I think you should look into not buffering tasks. Because then you can return them much sooner after you receive them. In addition, I think you should check if 14 threads is not too many.

With such changes, you will increase your probability of being the finder of more primes.


The buffer thing was a mistake. It was a setting for another project that runs out of work almost weekly and I wanted a big buffer so I had work during the periods the project didn't have any available. Some how that setting overrode all my other projects buffer settings. I have since fixed that issue. Instead of aborting all those tasks I have simply set Prime Grid to not get new work. I should be good for another 4 or 5 days at this rate.

As for the threads, my CPU has 16 threads and I reserved 2 for GPU tasks. I just put the other 14 to work on CPU tasks. I'm not sure how less threads would make things go faster. But I might try dropping it down as a test.

The 2nd prime that was found before the challenge (too late to be mentioned in the initial post above):

DeleteNull: 146264*5^2953282-1

A prime the was found during the challenge:

(pending verification): 238694*5^2979422-1


Its not my surname :(

Its mine and I am thrilled with it!

This is only my second prime and it is much larger then the first I found back in 2015. The 2015 find was Decimal Digits:388,341. This new ones dwarfs that at Decimal Digits:2,082,532.

I am getting the same GPU load fluctuation on my GTX 680. This causes my fan to speed up then slow down in time with the GPU load. It got annoying so I set the fan to run at a set speed fast enough to keep things semi cool.

Good question 1998golfer, I have yet to figure that out myself. Its not anything I can find in the project settings or in the Boinc client. Then again I am probably overlooking something obvious like normal.
