The above machines are interconnected via GigaBit Ethernet and/or 802.11G/N wireless. Our Internet connection is via 10 Mb/S burst mode wireless with 3G available as failover. All hardware is protected from lightening and power line disturbances by UPS. To ensure integrity of data in the event of loss or theft we are now using Full-Disk-Encryption (FDE) on all machines. All user files are archived on a server utilizing fault tolerant HW RAID 6 disk array. Automated backups are done nightly to encrypted media and snapshots are stored off site. Our primary OS is Ubuntu Linux. When necessary, we run Microsoft Windows applications from within VMWare virtual machines running on secured Linux host. If Windows is used on the hardware the disk is fully encrypted using TrueCrypt FDE software. For extreme computing tasks we have workstations outfitted with nVidia GPUs. Our GPU workstation uses dual nVidia Tesla C2070s and can provide more than 2 TeraFLOPs of throughput on CUDA enabled applications such as Remcom's X-FDTD simulator. Using GPUs we can now run and complete simulations in a matter of minutes or hours that would take day or weeks on traditional CPU machines. We also are exploring the use of Amazon EC2 (Elastic Cloud Computing) and GPU Clusters for the fastest possible throughput on the most demanding jobs. |
