I can create CSC matrices on the GPU, e.g. via cu(sprand(10,10,0.1)). How do I create CSR matrices? How do I convert a CSC into a CSR matrix on the CPU or GPU? I want to use csreigvsi, which requires CSR storage structure.

Call the CuSparseMatrixCSR constructor. Have a look at the CUDA.jl test suite (test/cusparse.jl and test/cusparse/*), there’s plenty of examples there.
