I have both matlab R2020a and R2021a. I have been using rtx 3090 GPU to do my calculations
I noticed preconditioned BiCGStab algorithm on R2020a is 3 times faster than the R2021a version using the GPU.
That doesn't make sense because R2020a has forward compatibility for my GPU where R2021a has native support for the ampere GPUs
If I'm missing something what could it be?
