Subject: Help on SHA-512

Hi

I'm working on OpenCL SHA-512 on John [1]. My code has some problem (see 
output below). Seems i'm failing on one small detail (and the devil 
lives on the details). Half of it works is fine, half not.

If someone knows enough about SHA-512 and kindly can help i really 
appreciate.

The final result is going to be submitted, so your are helping John 
community/users.

Thanks
