pconsole is a parallel console tool, and is meant as an interactive administrative shell tool for clusters. It allows you to connect to each node of your cluster simultaneously, and you can type your administrative commands in a specialized window that 'multiplies' the input to each of the connections you have opened.
Cplant (tm) is a collection of code designed with an emphasis on scalability, to provide a full-featured environment for cluster computing on commodity hardware components. Cplant (tm) system software provides a scalable message passing layer, scalable runtime utilities, and scalable debugging support. It is distributed as source code, which can be built for a specific hardware configuration. This consists of operating system code (in the form of Linux modules and driver), application support libraries and compiler tools, an MPI port, user-level runtime utilities, support for application debugging, and scripts for configuring and installing the built software.
Cluster Starter Kit for Linux uses Cluster System Management (CSM) software from IBM. With the Cluster Starter Kit for Linux's GUI, portions of CSM can be easily manipulated. Also provided is an easy way to view the status, change the status, or manipulate the conditions of nodes in a cluster.
Multixterm creates multiple xterms that can be driven together or separately. It can be used to login via SSH to multiple hosts and control them simultaneously, or for ad hoc things where you want to see the results as you type. Each xterm may also be driven separately. Multixterm is scriptable so that you can easily fire up, for example, a dozen xterms with a single command, tiled nicely on your screen. In addition to SSH, multixterm can drive rlogin, telnet, passwd, or any program that runs in an xterm.
