I am the technical manager in a reservoir simulation project and working with various self made and existing math libraries for my speed comparisons. I use ILU (Incomplete LU) factorization on a version of BSR (blocked sparse row matrix structure) and I like to use MKL's solution in this area but I just find dcsrilu0 and dcsrilut. I wonder whether there is something like dbsrilu0? Because as I know it is a key part of every reservoir simulator and I think MKL supports this kind of requirements. Can anyone help me in this area?
