This is addressed mostly to people using the Parallel Computation Tool
kit.
The problem that I have is that I want to run a task using a series of
remote nodes that are behind a firewall or part of a beowulf cluster
but using a local frontend on my desktop computer.
i.e envision the following topology:
(me.edu)----(beowulf.edu)
|
+ (node1.beowulf.edu , node2.beowulf.edu,
..... )
where node#.beowulf.edu are nodes within the beowulf cluster
or behind a firewall that cannot be accessed directly via the internet
but can be accessed from within by logging on to the main node of the
cluster.
Is it possible to set up a RemoteSlave from my desktop to
the main node (beowulf.edu)
and have it launch RemoteSlaves on the internal nodes?
The alternate (which works fine) is to open an X11 window for a
remote front-end on beowulf.edu and go from there. The trouble is that
the cluster itself is located at a remote location (across campus) and
I hate
to waste the bandwidth and cycles keeping a window open.
Any suggestions?
Thanks,
Eric Bittner
