Sieving S180 from n=10000 to n=25000. Will complete to 1e12 by the end of the year, but don't know how deeply it will need to be sieved.
Sieving R66 from n=25000 to n=50000. Since there are so many k remaining, I will break down into 10 chunks with the last chunk including the few k > 101e6. I expect to sieve to about 1e13, but that is just a guess. If 1e13 is correct then I estimate about 3 months per chunk so across two GPUs, it is unlikely that I will finish it in 2023, but one never knows. Last fiddled with by rogue on 20221205 at 20:00

I have sent Gary sieve files for:
r247, r250, r310, r312, r357, r375, r388, r465, r535, r660, r685, r838, r970, r975, r1005, r1018 s190, s303, s306, s357, s361, s385, s486, s537, s540, s575, s612, s673, s675, s717, s750, s775, s786, s861, s885, s970, s975 all are sieved to 1e12, which should be plenty deep for anyone wanting to work on them.

Currently sieving R42 the 26 kvalue at once. Expect end of sieve... next month maybe?

As a first time contributor here...
R53 seems to be available? I'd like to do it 100k250k and sieve it at least to 1e13 with OpenCL.

Are you sieving only or both sieving and testing? 77 k's would be a huge effort for sieving and testing n=100k250k. It would even be big for our BOINC effort. But you're certainly welcome to do that. If it ends up taking longer than you'd like, you can always stop. Last fiddled with by gd_barnes on 20221215 at 19:49

I recommend to take some of these 2.510k bases and sieving (takes around 35days with W16 on Ryzen), the main problem is to occupy all cores of the CPU, BOINC is the best option for this, for smaller bases, Iam creating 16 folders every time, split the k and use the stoponprimek=1 option in llr.ini, this reduce the overall time.

My plan was sievingonly since the GPU I want to use is idling otherwise.
