Summary
The LiveWN project’s primary goal is to add computational
resources to the Grid in a
simple way, user friendly enough that non-experts can use. So
far, no one has
accomplished fully dynamic resource management on the LCG/EGEE
grid, since there has
to be coordination at the system administration level in order to
tune installation
parameters, like hostnames, domain, etc. The LiveWN image is a
technology that solves
this problem in a versatile way so that Worker Nodes (WNs) can be
setup and used
behind firewalls, within virtual machines, over dial-up lines,
etc. We have tried all
these alternatives and it just works, without requiring any
significant expertise.
The LiveWN solution is a mixture of three technologies, already
supplied by others:
- A Knoppix-like LiveCD
- LCG/EGEE middleware
- An OpenVPN IP tunnel
GRNET is the coordinator of the HellasGrid project, promoting
Grid technologies in
Greece and participates in regional Grid activities in South
Eastern Europe.
GRNET is actively exploring the idea of integrating resources
that are available
within the academic community in Greece, by engaging with the
National Technical
University of Athens, who is the original provider of the LiveWN
technology. We
envisage that this approach, which combines CPU scavenging and
Grid technologies
could allow applications in dynamic worldwide Grid environments.
