Post: 256 x 256 matrix multiply have comparable speed on cpu and gpu ... binaries i upload tommorow evening. 128k ? complex points is how many floats ??? because you can upload only 2048 x 2048 float4 texture onto many gpus... sorry for my stupid questions but i am working with seti source 5 hours only... |

Post: brook compiler : SSE2 + max optimization with VS2005 + SP1 x86 compiled brook runtime : SSE2 + max optimization with VS2005 + SP1 x86 compiled selected dx9 brook backend GPU : NV43 (6600 PCIE) cpu : Athlon64 3000+ @3400 939 socket(512kb cache) cpu multiply : standard math algorithm (3 loops) test app : SSE2 + max optimization with VS2005 + SP1 x86 compiled ( i think that cpu multiply is in SSE2 from compiler not from me) ok there are some numbers : matrix multiply 1024*1024: with brook : 2 sec cpu only : 30 sec for fft send me matrix representation of algo , but i think its similar to dct ? seee difs ... |

Post: Hans have you tried a BrookGPU ? i have implemented in brook a (i)dct algorithm and its a nice fast (ffdshowtryout). brook is very simple and nice optimized maybe i compile some test program ... |
