for r=8:

[a@...er run]$ ./john --test --format=yescrypt-opencl --dev=5
Benchmarking: yescrypt-opencl [Salsa20/8 OpenCL (inefficient,
development use only)]... Device 5: GeForce GTX TITAN
memory per hash : 2.10 MB
DONE
Speed for cost 1 (N) of 2048, cost 2 (r) of 8, cost 3 (p) of 11, cost
4 (t) of 0, cost 5 (g) of 0
Raw:    718 c/s real, 718 c/s virtual
