[petsc-users] Regarding the status of MatSolve on GPUs

Hi PETSc-developers, Does PETSc currently provide (either native or third party support) for MatSolve that can be performed entirely on a GPU given a factored matrix? i.e. a direct solver that would store the factors L and U on the device and use the GPU to solve the linear system. It does not

Hi Eric, With the previous Intel version I was able to configure without mpi wrappers without problems. Using the suggestion by Mark (CFLAGS, FFLAGS, CXXFLAGS) I managed to also use the mpi wrappers. Unfortunately, as you seem to have noticed, things break down on Hypre and that loopopt. I

Hi, everyone, I am trying to run some test cases with x window, but the x window never showed up with command `make -f ./gmakefile test ...`. It seems a default option `-nox` is set. How to disable this option for `make test`? An example is shown below: ``` z2yang@ws6:~/repos/petsc$
