I didn't believe that shared memory is very fast. I wrote version app which using shared memory. On my card it's only 16kb for every block of threads. It's very small but i tried use that for encrypt/decrypt. Version without shared memory worked 76 seconds but with shared memory only 50 seconds. It's increase about 35% performance. I'll trying increase performance more. Edited at 2011-02-24: My last version of nDES CUDA works about 59% faster using SHARED MEMORY on my 8600m gt. It's very good for me but i'll try increase it more :)

Yesterday I compiled WINE 1.3.7 (32bit) on 64bit debian. I had problems with libs. I didn't resolved V2L and gstreamer. Without it wine works ok. Its better that 1.1.42 from repo. If you want install it, i'll send you .deb for amd64 distro.

I was afraid then I was compiling kernel with gcc-4.5.1 because gcc-4.5 has problem with kernel size compression. It's done and works. I noted increase reading disc speed form 60mb/s to 71mb/s. Also I noted increase nVidia card performance about 5%-6%.

I wrote & tested my implementation of n-DES (encryption algorithm)  for my thesis. It's support nVIDIA CUDA, CPU SINGLE CORE and CPU MULTI CORE. I think that i can't put here code but i can send binary version. If you want help with performance diagnostics on different cards write comment. Picture from Wikipedia.com
