[petsc-dev] better regular testing on accelerators

[Smith, Barry F.]

   In order to get better testing on the accelerators I think we need to abandon the -vec_type cuda approach scattered through a handful of examples and instead test ALL examples that are feasible automatically with the various accelerator options.  I think essentially any examples that use AIJ are feasible for testing (those that use BAIJ, SBAIJ, Ell are not) I am not sure if there is an automatic way to determine all of these cases. Labeling all such test cases manually would likely miss some and be out of date immediately.

   Any thoughts?

   Thanks

Maybe we could short circuit the issue by having a mode of configuring or compiling or running where MatCreate_AIJ and VecCreate_ are bypassed directly to the accelerator cousins (this is not completely trivial because the cousins generally construct the basic ones and then convert themselves to the cousin).
