4 The Modern High Performance Computing Environment     continued...

In today's high performance computing environment, a computational scientist's routine activities rely heavily on the Internet. Activities include exchange of e-mail and interactive talk or chat sessions with colleagues. Heavy use is made of the ability to transfer documents such as proposals, technical papers, data sets, computer programs and images. A networked high performance computing environment provides the computational scientist access to a wide array of computer architectures and applications. Using telnet to connect to a remote computer (on which one has an account) on the Internet enables the computational scientist to use all of the computational power and software applications of that remote machine.
