Split batched solver compilation #1629

Open MarcelKoch opened 1 week ago

MarcelKoch commented 1 week ago

This PR splits up the compilation of the batched solvers in order to reduce the compilation times. It splits up the instantiations of the kernel launches depending on the number of vectors in shared memory. This is based on the same CMake mechanism as for the csr and fbcsr kernels.
