PETSc Debian package switch to lam?
Greetings,
[petsc-users, this only affects you if you run Debian GNU/Linux.]
With my big cluster not quite up yet, I can't quite do the big mpich vs.
lam benchmark I had hoped to, and have to trust the judgment of others.
There seems to be a rough consensus that lam is better (from people
like Eray Ozkural on debian-beowulf), so with freezes approaching, I'd
like to switch the Debian package to use lam.
I don't know how many Debian PETSc users there are, but what this would
mean is that either you'd have to recompile your PETSc-based apps
against the new -dev packages, or build mpich-based PETSc libs, or just
not upgrade from 2.1.0-1. (I think petscgraphics is the only Debian
package depending on it.) Since the package is still in
unstable/testing, I do this with little remorse, but if there is valid
technical justification (within a week or so), I'll stick with mpich.
As for "why not binaries for both?", PETSc is huge, weighing in at 56 MB
in pool/main/p/petsc (65% of which is the -dbg packages), and for the
mirrors' sake, I'd rather not double that.
Zeen,
