Here are the new results (still no tuning):

user@...l:~/john/magnum-jumbo/run$ ./john -te -fo=wpapsk-cuda
Benchmarking: wpapsk-cuda [GPU]... DONE
Raw:    27015 c/s real, 27151 c/s virtual

user@...l:~/john/magnum-jumbo/run$ ./john -te -fo=wpapsk-opencl
OpenCL platform 0: NVIDIA CUDA, 1 device(s).
Using device 0: GeForce GTX 570
OpenCL error (CL_OUT_OF_RESOURCES) in file (opencl_wpapsk_fmt.c) at line (125) - (Run kernel)

user@...l:~/john/magnum-jumbo/run$ ./john -te -fo=wpapsk-opencl -pla=1
OpenCL platform 1: AMD Accelerated Parallel Processing, 2 device(s).
Using device 0: Tahiti
Optimal Group work Size = 64
Benchmarking: wpapsk-opencl [GPU - OpenCL]... DONE
Raw:    40069 c/s real, 100800 c/s virtual

For comparison, this used to be "64000 c/s real, 531692 c/s virtual".
So the real speed has decreased, and the CPU usage has increased.

Did you say that the old speeds were somehow not real?  Was there some
kind of bug (incomplete implementation?) that you fixed?

user@...l:~/john/magnum-jumbo/run$ ./john -te -fo=wpapsk-opencl -pla=1 -dev=1
OpenCL platform 1: AMD Accelerated Parallel Processing, 2 device(s).

Raw:    2094 c/s real, 266 c/s virtual
