So we have a winner! -gpucurves 2560 beats all the others and anything the old build could do as well (best on the old build was 5120 @ (~25 ms/curves))

With the smaller kernel (running (2^499-1) / 20959), -gpucurves 5120 is fastest at about 6ms/curve on both new and old builds.
Two late night performance thoughts.
1. You might get 10% more throughput by toggling VERIFY_NORMALIZED to 0 on line 55
It's a nice debug check while this is still in development but it has never tripped so it's overly cautious especially if it costs 10% performance.
2. Would you mind sharing what card you have and the full output from -v output (especially the lines that start with "GPU: ")
