[petsc-users] Multivector Object

[Henc Bouwmeester]

Hello all,

In section 4.2 of the manual, it is stated that the only option for solving
linear systems having the same preconditioner is to call KSPSolve() multiple
times.  However, when dealing with such a system, one can take advantage of
DGEMM when updating the vectors as a 'multivector'.  Has anyone attempted to
create a multivector object in PETSc?  If so, what is the interface and
where can I find the code?  If not, can anyone speak to the difficulties?

Thank you,
Henc
