I'm happy with the state of scalapack 2.0.2 now, and in principle am
ready to drop it into unstable.
All linux arches pass openmpi tests
(except mips64el, which I've currently set to ignore test errors.
xdsyevr fails abjectly, makes me wonder if it's a mips64el openmpi bug.
Other tests segfault randomly (unreproducibly)).
Testing a couple of dependent debichem packages, the transition looks
like it should be straightforward. The API hasn't changed as far as I
can tell. Just update any -lblacs-openmpi reference to
-lscalapack-openmpi, and adjust -L paths to multiarch if necessary.
Does debichem need more time to test the transition?
We might need to first wait for the libgfortran4 transition. I'll ask
release managers to advise on that.
