[petsc-users] Parallel ODE solver

[Patrick Sanan]

Further note that you can use sundials from within PETSc, without any
more hassle than supplying a configure flags (--download-sundials, or
see the other entries under SUNDIALS: with ./configure --help).
That could potentially be very helpful in moving to TS.
