| Popis: | We describe design and implementation of virtual private grid (VPG), a shell that can utilize many machines distributed over multiple subnets. VPG works around common security policies (e.g., firewall, private IP, DHCP) that restrict communication between machines and even break uniqueness of IP addresses. VPG provides the following functions: (1) a unique nickname to each machine that does not depend on a DNS name or a fixed IP address; (2) job submissions to any nicknamed machine; (3) redirections from/to a file on any nicknamed machine; (4) pipes between commands executed on any nicknamed machine. VPG implements the above functions by constructing a self-stabilizing spanning tree among machines and forwarding messages via a path in the tree. We ran VPG on about 100 nodes (270 CPUs) and measured a turn around time of a small job submission with VPG and other tools: rsh, SSH, and globus-job-run. The experimental result shows that VPG can submit a job faster than SSH and globus-job-run, since VPG performs authentication only when it constructs a tree. |
