Some of the PETSc examples are crashing under some circumstances (like with complex) using PLAPACK and valgrind is showing uninitialized variables etc in PLAPACK code. I don't want to debug PLAPACK code, so will let it go for this release.<br>
<br>
BUT, is there something else we can move to for petsc-dev in the future. Should we throw away the use of PLAPACK and use FLAMELIB? Should we switch to ScaLAPACK (just kidding?). I hate to bag dense parallell matrices from PETSc completely but don't want to spend a lot of time on whatever we do support.</blockquote>
