The different groups working on the
Xibalba cluster do rely on vastly different operating
systems and different middleware packages. The database
group in the powerDB project works with Windows 2000
and the SQL Server database management system provided
by Microsoft Corporation in a research agreement.
The other groups do work with different flavors of
LINUX, which can be quite specifically configured
to their experiments. The architecture group maintains
its minimal service operating system for diagnostics
and maintenance and a setup with experimental communication
system software for benchmarking and application with
particularly high communication demands (high bandwidth
and low latency). To support all the different needs
the Xibalba system is conceived as a multi-boot system.
Each node can be configured to boot in any of the
operating system configured. In addition to the pre-installed
operating systems the cluster is equipped with ``Dolly'',
a specialized software distribution tool that uses
Xibalba's powerful networking infrastructure to distribute
entire new software installation within minutes.
