Overview of CNGL School Cluster Desktop PCs and Future Plans

DESCRIPTION

This document provides a comprehensive overview of the computing resources available at the CNGL School Cluster. It details the configurations of both current and future desktop PCs, comparing older Pentium 4 systems with new Core 2 Duo and Xeon setups designed for scientific computing and complex systems modeling. Features include various hardware specifications such as RAM, storage options, and total core counts, alongside information about RAID protection and future machine tenders. It serves as a resource for project planning and resource allocation.
