[petsc-users] Dense Matrix Factorization/Solve

[Sreeram R Venkat]

I have an SPD dense matrix of size NxN, where N can range from 10^4-10^5.
Are there any Cholesky factorization/solve routines for it in PETSc (or in
any of the external libraries)? If possible, I want to use GPU acceleration
with 1 or more GPUs. The matrix type can be MATSEQDENSE/MATMPIDENSE or
MATSEQDENSECUDA/MATMPIDENSECUDA accordingly. If it is possible to do the
factorization beforehand and store it to do the triangular solves later,
that would be great.

Thanks,
Sreeram
