[Beowulf] Create cluster : questions

[Bernard Li]

For those who are interested in this discussion, I'd like to point you
to the openSUSE Build Service (in alpha stage):

http://build.opensuse.org

They have a web GUI/CLI for performing automatic builds of packages and
they not only support SUSE Linux but also other distributions like
Fedora, Mandriva, Debian and Ubuntu in x86 and x86_64 configurations.

I am currently maintaining some HPC-related packages via the service.

Cheers,

Bernard
