Implementing an ADI method in parallel

[David Knezevic]

Hello,

I was hoping to get some advice on whether the following is possible in 
PETSc: I want to implement an ADI-like method, in which I want to do 
multiple uniprocessor linear solves concurrently (each linear solve is 
quite small, but there are a lot of them).

This isn't what PETSc is designed for I guess, since one would typically 
do one large solve with multiple processors, but I was wondering if 
there is a good way of implementing this kind of ADI-like method in 
PETSc? Or should I instead implement this kind of thing using a serial 
linear solver, and control the concurrent solves with MPI? I'd prefer to 
stick to PETSc if possible, since it has so much nice functionality 
bundled in it, and has a lot of the MPI stuff already taken care of...

Thanks very much for the help.

Regards,
