Let’s say I have a sparse set of matrices A1, A2, ... An, each of type CuSparseMatrixCSC{Float32, Int32} along with associated RHS vectors b1, b2, ... bn. Is there some watch to do a batch LU solve on the GPU with CUDA.jl? If the matrices are dense, getrf_batched! works fine to get the LU factors. …

Batched LU solves (or Factorizations) with Sparse Matrices

how big are the a matrices? you might just want to treat them as dense
