[petsc-users] QR factorization of Parallel Dense Matrix

[James A Charles]

I did some more investigation into this problem. Do you think using Scalapack for the QR factorization would be my best bet? If so, How do I interface Petsc to Scalapack? Are the parallelizations of the matrices in Petsc compatible with Scalapack?

Thanks,
James

What dimension is the matrix and how do you want the factors distributed?
