Abstract
We provide an integrated environment to the users of
clusters for scientific computation. The environment
simplifies the overall usage of the system and makes it
easier for new users to learn and start using the system. It
is an attempt to integrate the various pieces of software
that comprise the user environment of an open-source
based Linux cluster without introducing limiting constraints.
We target this environment towards users who
consume the system's volatile resources (CPU time and
network bandwidth) to do research in physics, chemistry,
and other application areas. It does not require any
additional code in the application as long as the used
communication paradigm is supported on the system.
Instead, researchers with own code find it easy to build
and run their program.
This work also extends into the realms of system administration,
where tools and the configuration of the
system make it feasible to provide more informative services
to users.
This environment is currently in use on two clusters
which are used extensively for research in physics and
chemistry.
