Subject: opencl patch for 1.7.8-jumbo5

hello,
i've just uploaded patch on the wiki :

http://openwall.info/wiki/_media/john/john-1.7.8-jumbo-5-opencl-1.diff.bz2

This patch fix problems with john-1.7.8 as stated by groszek.

I've added, thanks to the work of Alain, find_best_workgroup
function that will try to detect dinamically best workgroup size
for your card.

this function is in all of 4 formats, and should help a bit.

With some free time i could try to faster a bit cracking by
putting hash check inside the cl code and just return
1/5 hash + 0|1 (if cracked or not) ; this should speed up even
more the code since you could save bandwith while "downloading"
hashed from the GPU to CPU.

After this step i'm planning on moving to DES and see what i can do,
if someone is willing to help everything is welcome i'm in trouble
at the moment trying to find free time from work .


Regards
Samuele
