Hello, guys！ Recently, I’m using NVIDIA GPU to solve large sparse matrix linear equations by calling cuSparse library and testing the solution speed on different GPUs. Unfortunately, I have encountered an incredible problem. According to the instructions given by NVIDIA,the A100 has more powerful c…

Calling cuSparse library on Tesla A100 with CUDA11.1 is much slower than that on Tesla P100 with CUDA9.0
