Samurai is the name of our GPU development machine. It is also the machine that hosts the wiki and the svn repository for our codes and papers. Its web address is samurai.phys.gwu.edu.
Machine description
Samurai is single processor, quad core machine running at 2.4 GHz. It has 3GB of memory and a 640GB harddrive. The motherboard on samurai is Foxconn P45A-S; the most important characteristic is that is supports PCI Express 2.0 and that it has two x16 expansions slots. The PCI Express 2.0 bus should allow for a 8GB/s bandwidth for the x16 slots where the GPU is connected.
The GPU on this machine is XFX-GX280 a gtx280 GPU.
GPU Engine Specs:
| CUDA Cores | 240 |
| Graphics Clock (MHz) | 602 MHz |
| Processor Clock (MHz) | 1296 MHz |
| Texture Fill Rate (billion/sec) | 48.2 |
Memory Specs:
| Memory Clock (MHz) | 1107 |
| Standard Memory Config | 1 GB |
| Memory Interface Width | 512-bit |
| Memory Bandwidth (GB/sec) | 141.7 |
Adding a user
To add a user you need to login as root or use sudo if you are one of the users allowed to use it. The simplest way to add a user is to use adduser script - if you type adduser USERNAME the script will ask you to select a password and to input some basic info about the user and then create the account.
IMPORTANT: if the user needs to use the GPU you need to add the user to the video group. This is done by adding his username to the video group list in the "/etc/group" file.
