Virtual Private Grid :
A Command Shell for Utilizing Hundreds of Machines Efficiently
Virtual Private Grid (VPG) is a command shell that allows a user to
harness hundreds of machines efficiently and easily. More specifically,
VPG provides the following functions.
- Nicknaming (VPG gives each machine a unique name)
- Job submission to a nicknamed machine
- Redirection from/to a file on a nicknamed machine
- Network pipe between nicknamed machines
Here are some examples of the remote job submission with VPG.
- command@host executes the command command on host host.
- tar@hostA -c file | tar@hostB x compresses the file on hostA, transfers it to hostB, and extracts it on hostB.
Comparison with Other Tools
VPG differs from existing job submission tools (e.g, rsh, SSH) in that
it semi-automatically works around restrictions imposed by administrators
(e.g., private IP, firewall, DHCP client).
For example, when submitting a job to a machine behind a firewall with
existing tools, you usually need to first log onto a gateway machine
and then onto the target.
% ssh gateway
% rsh tuba ls
One the other hand, using VPG, you can directly submit a job only by
specifying the target with its nickname.

This version of VPG is intended to run on Unix-like systems. In
particular, we have test VPG on the following platforms:
VPG should also run on other systems, provided GNU systems (e.g.,
gcc, make) and POSIX threads are available.
- Linux on x86 processors
- Solaris on SPARC processors
