Also, to provide a data point that might be of interest: this was run on a GTX 980 Ti and averaged ~3500 M/s raw rate with a SievePrimes of 100k. That represented the highest throughput, testing from the largest SievePrimes of 1075k and stepping down.

No further reservation right now as I need the GPU for some other work, but I'll be back for sure. :smile:

I'm done with n=70-73 of my current reservation. [B]I'll release the n=74[/B] due to some problems (again) with the computer.
