It's hard to say
now I'm getting the same speed all the times
[a@...er run]$ GWS=1344 ./john --test --format=lyra2-opencl --dev=5
Benchmarking: Lyra2-opencl, Lyra2 [Lyra2 Sponge OpenCL (inefficient,
development use only)]... Device 5: GeForce GTX TITAN
Local worksize (LWS) 64, global worksize (GWS) 1344
DONE
Speed for cost 1 (t) of 8, cost 2 (m) of 8, cost 3 (c) of 256, cost 4 (p) of 2
Raw: 6000 c/s real, 6000 c/s virtual
