Dear Colleagues!

I would like to receive information on how to solve a large linear
equation system on a parallel computer. The coefficient matrix is
sparse, neither positive definite nor symmetric. I solve the system on
a sequentiall machine with a iterate method (BiCGstab). How can I
apply the solver on a parallel computer? 

-) What domain decomposition technique is appropriate (Schwarz -
   Schur)?

-) What preconditioning can be
  applied? 

Mit freundlichen Gruessen			Frank Dzaak.
