Thank you very much. Actually I just used the petsc-dev code and it worked without any problem.  Thank you very much for your help.

By the way, could you please suggest a petsc test case of KSP solver on the Blue Gene? There are many tests coming with PETSc. It would be great if I could just focus on one test.

Thanks again.
