Hi everyone, I'm using PETSc to solve saddle point systems. I have found a block preconditionner which requires to solve a smaller symmetric positive definite system. I do it with MUMPS which is fast an robust. However, I would like to use this solver in single precision in order to compare the performances.
So is it possible to use MUMPS in single precision inside a double precision solving with PETSc? Thanks, Sylvain
