WebFeb 19, 2024 · Thanks for your questions. I’ll update more numbers with cublas later. Cutlass doesn’t have dependent on shapes, it has stable optimal performance for all kinds of shapes for both GEMM and conv. And its template has slight difference for different SMs or instructions which you can reference its open source code for better details: GitHub - … WebSep 21, 2015 · That means the matrix needs to be treated as differently on the device than on the host. The CUBLAS APIs (like any BLAS), support operating on matrices stored in transposed order (ie. row major order), and the OP is trying to use this to perform a dot product. It's possible to use matrices that are stored in row-major order with cublas, and ...
WebI started to learn CUDA last year, and started writing matrix multiplication kernels as a learning project. After some struggles, I made them to work, but then got disappointed when I saw my kernels are 10 times slower than cuBLAS GEMM kernels. Maybe my expectations were a bit too high. I’ve tried lots of open sourced matmul kernels on … WebMar 21, 2024 · This example demonstrates how to use cutlass to compute a batched strided gemm in two different ways: By specifying pointers to the first matrices of the batch and the stride between the consecutive matrices of the batch (this is called a strided …
