I should be able to finish all 39 conjectures at n=10k that are sieved < 1e12 to 1e12 by January. I have 3 GPUs happily sieving away at them.

With which program? This is a big task.

srsieve2cl. Currently approaching P=1e10 in the next day or two.

Nice. What command line oparameters are you using?

It took a little trial-and-error (and is likely not optimized), but I'm currently running with -g16 -K8 -M500. I think the -M option is only necessary because I'm starting at such a low p-value. I may try a smaller value with -K as well.

Currently, those options give me throughput of ~2.5k-2.8k p/sec (depending on if something else is using the GPU) at p=500e6 with a found factor rate of ~180/sec. CPU was giving around 200 p/sec for comparison.

I posted srsieve2cl at sourceforge. Take a look at the -b parameter, which is new. By using -b you might be able to reduce -K, which can in turn increase throughput for the GPU. Removing terms will not allow you to adjust -K, only removing sequences.

Will do. Thanks!

We are currently working on sieving the remaining bases with 3 k's remaining at a search depth of n<500K. Most already have sieve files but there are a few without them.
