If you look at this chart and search for "950", you'll see that 220 GHz*d/d is pretty good.

Nice graph. So... anyone got a couple Tesla 100v cards they could spare for me? LOL

Seriously, they all offer them. But they aren't cheap.

Tesla V100 for what? The can do exactly 0.0000000000GHz equivalent in TF today!

Ofc. they are more fun for LL

Any understanding as to why?

Your code was some of the best CUDA. And then it suddenly went to zero.

Weird.

There are a couple of settings at the bottom of the mfaktc.ini file that are worth playing with.

You can play with the sieve size and see if enhancing it you get any speedups...

Yep, follow the link and read a little bit. Seems for each new HW family they f*ckup something in their compilers. With CUDA 9.0 and 9.1 mfaktc just fails every single testcase in the builtin selftest and refuses further work thus 0GHz equivalent today just because it doesn't work. They (nvidia) told me they found the bug and next CUDA release should fix this. For Volta I don't really care because those chips should do LL not TF! I'm more concerned about the nextgen consumer/gamer generation GPUs.

As mentioned, there are a few settings in the mfaktc.ini file that can be adjusted to improve performance; I've seen throughput improve by over 10% with my GT1030.
Congrats on getting the code compiled and enjoy the TF fun!
