Subject: Agnieszka's weekly report #4

accomplishment:
I didn't do much in this week
-I was optimizing parallel-opencl but I didn't gained much speed
-I reformatted my version of pomelo, previously I had some magic with
value 255 and other ugly things

priorities:
-still I will be working on parallel-opencl
-I'll port optimized version of parallel from
https://github.com/Sc00bz/Parallel if the author complete this. If
not, I'll do something else


speed for parallel-opencl:

[a@...er run]$ ./john --test --format=parallel-opencl  --dev=1 --cost=0:0
Device 1: Tahiti [AMD Radeon HD 7900 Series]
Building the kernel, this could take a while
