= Matrix Multiply on GPU = We have implemented single/double precision matrix multiply program for RV770/Cypress. In our implementation, we use two input streams. One is transposed input matrix A and other is input matrix B in normal format. Output matrix C is also not transposed. We adopted 8x8 block for single precision and 4x4 for double precision. Here is benchmark result for each case. Note only kernel execution time is measured. == Single precision == [[Image(SMM.png)]] == Double precision == [[Image(DMM.png)]] = Useful forum discussions = == Discussion on a highly optimized MM kernel == http://forum.beyond3d.com/showthread.php?t=54842 == Discussion on MM kernels in OpenCL == http://forums.amd.com/devforum/messageview.cfm?catid=390&threadid=127963 === IL code generator in C++ === CAL++ http://sourceforge.net/projects/calpp/ Meta-programing works in reality.
