What has happened to your plans to implement storage of loaded hashes and/or salts on the GPU end, though? And to support occasional long passwords while not hurting performance for short passwords? Also, you wanted to comment on "Password Generation on GPU", but I think you never did (I exchanged a few messages with Frank, and that's all). I understand that you can't work on too many sub-tasks at once; I am merely asking, recalling that this stuff was previously among your Priorities, and seeing that now it just disappeared. > I am stuck at my xsha512-opencl on 7970.

If not, would providing you with remote access to one be of help (to see if the issue is with code generation for 7970 specifically or with AMD APP SDK or driver in general)? Oh, I recall that Samuele reported that your code failed on his 6970 as well, right? Thanks, Alexander
