WebJun 8, 2024 · A naive GEMM (using 3 for loops) usually gets around 3-5% of the processors peak performance. A blocked GEMM without any other optimization (6 for loops) gets around 20% of the peak performance. The matrix multiply MATLAB uses is Intel MKL's GEMM which is tuned for different processors and can get around 80-90% of the … WebJun 4, 2024 · I am having a hard time understanding how to multiply blocked matrices with rectangle matrices and blocking into non-square matrices. Can someone please explain me how that works? Stack Exchange Network

WebFeb 19, 2016 · In modern implementations, conventional matrix multiplication implementation (in the form of highly optimized versions of the BLAS xGEMM function) use blocked algorithms that are carefully tuned to match the cache size of the processor. In comparison, Strassen's algorithm is extremely cache unfriendly, and this makes it difficult … WebApr 5, 2024 · I want to perform a block matrix multiplication (Divide a matrix into multiple BLOCK_SIZE x BLOCK_SIZE matrices and multiply the corresponding blocks). I've written some code, but want to improve it and store blocks that are above the main diagonal but I don't have any ideas. Can you guys please help if possible? on the beach scam
