The above machines are interconnected via GigaBit Ethernet and to the Internet via ADSL modem. Peripherals include HP LaserJet 6MP printer, Epson 2000P Photo Printer, Canon FS-4000 35mm film scanner and Epson 1640SU page/transparency scanner. All hardware is protected from lightening and power line disturbances by APC Smart-UPS battery backups. We are now using Ubuntu Linux with full-disk-encryption as the host operating system on all computers. We use Microsoft Windows applications only in a VMware virtual machine environment running on the secured Linux host. This approach to managing multiple operating systems enhances security and manageability while reducing the number of physical machines that must be maintained. For extreme computing tasks we are now making use of the Amazon Elastic Cloud Computing (EC2) environment and an nVidia Quadro GPU that provides nearly 1 TeraFLOP throughput. |
