can i have this php script? or the list?

before i told you that i would have the best performance with 768 threads and 7 blocks under win7.
i tested the new alpha under linux 64 bit and there i got the best results with 300 threads and 900 blocks. but it doesn vary too much from the normal speed without choosing manually threads and blocks. of course lookup is active. i can get about 20-40 M/s more than in windows but the screen is slower too. the only problem is that under windows 7 i could do it with 768 threads and if i do that under linux i get that ressource error. but great work this beta!

The defaults for the 0.7 series are pretty bad for Fermis. I'm working on improving that.

I'm surprised you're finding best results with a non-power-of-32. Usually threads should be a multiple of 32 (the warp size), and I've found block sizes of multiples of 60 work nicely.

Linux is a better environment for this. The Windows driver model really sucks. The fact that you're getting significantly more speed points to this fact The tools are really designed for a headless Linux environment, they just happen to work tolerably with GUIs under Linux, and work with GUIs under Windows.

As for the PHP script... not difficult. Just generate random character strings, run it through the built in md5 function, and output to a file. I don't keep simple stuff like that in version control.

oh you're right! I somehow forgot to test 320 threads! with that change i got 30 M/s more! quite impressive!
but if i change the charset to numericwith length 14 this configuration is quite slow. if i change it to 256 threads and 300 blocks i get hardly twice M/S! For charset numeric that was the best i could find.
