That must be a fast siever.
I will have to try a range with srsieve on my new Ryzen 9 that I just got 3 months ago.

p=702338392703, 25.26K p/sec, 8318 factors found at 9.99 sec per factor (last 1125 min) It is down to about 3.2m candidates. I will stop when the removal rate reaches about 1 factor per 15 seconds.

I suppose that maybe you will be testing on slower machines, which maybe makes 15 secs better. But just thought I'd point it out. Last fiddled with by gd_barnes on 20210122 at 01:59

15 seconds is the time for a single test on this laptop at n=80000. I'll switch over to testing the range.

My rule of thumb for CRUS: Sieve on my fastest sieving machine until the removal rate equals the test time of a candidate at 5060% of the nrange of the average of the machines that I will be testing on. Those machines that I will be testing on may or may not include the fastest siever.
I just checked out all that sieving that I did for R3 using my newer Ryzen 9...a machine that I did not have when I did the sieving. Since it's an AMD it should be somewhat faster at sieving than Intels by my experience. It was. Using srsieve at P=35G I was getting a test removed every ~9 seconds. Using the Intel that I had used before it was about every ~1012 seconds. With an average test time of 68 seconds at n=70K80K as stated previously, from my perspective P=35G was slightly oversieved for the entire k=25G55G range. I wanted to check it with the Ryzen in case it was significantly faster and I could justify sieving some more. It wasn't enough faster to do so. From your perspective it looks like you could have stopped sieving at P=~400G somewhere using your super speedy siever assuming that your average test time is similar to mine. Anyway...just food for thought if you sieve k=36G37G for your next set of testing.

I only have one machine that can sieve 4000 or so sequences (enough for a 1G range of R3) in the GPU. I just kicked off the 36G range.
Since I will be using PRPNet to manage the testing, I can statistics in the database to estimate the average PRP test on the same computer. After a few days (or a week) I should have enough data to determine the optimal factor removal rate, although I believe that your estimate of 400G is very close.

On the computer where I'm doing the sieving tests take about 12.5 each on average.
But since I have multiple computers, the average across all of the cores is 7.5 seconds per test. That is my sieving target removal rate. In short, if using srsieve2cl, this is going to be based upon the average test time of the various cores you are using for PRP testing. With my cores a range of 1G will take about 17 days of PRP testing. Last fiddled with by rogue on 20210126 at 15:18

R3 35G is done to n=100000. Primes are attached.
Gary, do you want residues for this range?

Are you reserving the next 1G range? Or should I just wait until you reserve each range? Last fiddled with by gd_barnes on 20210205 at 22:41
