CCM Computing Equipment Overview

Servers

math.cudenver.edu Operating System Fedora 8, Dual Opteron 248, 8GB RAM, This system has home file systems and provides email and web services. Avoid running computation intensive applications on this system.

For computation or memory intensive applications please use one of the Following servers. Each of these have most of the math and software developement related applications installed that are avaiable in their respective OS (Operating System) distribution. Matlab and Mathematica are also available on each of these.

• game1 Intel(R) Core(TM) i7 CPU 965 @ 3.20GHz, 8 cores total, 12 GB RAM, running Fedora release 12
• godzilla Pentium 4, 3.0 Ghz , 4GB RAM, running Fedora release 12 (the only 32 bit Linux system)
• xvia & xvib Two similar systems each with Fedora 10 OS, 4 Quad Core Opteron 2.0 Ghz CPUs, 64 GB RAM
• tesla1 & tesla2 (not currently available) Front ends for a Tesla S1070 GPU (960 CPUs) with CUDA developement tools.
  We have 7 CUDA capable workstations for CUDA developement with accounts available on a per-request basis. Microsoft Windows and Linux CUDA developement environments are available.
• ldpe (Linux Dell Power Edge) Alternate to the math server for workstation linux desktop, Intel(R) Xeon(R) CPU X3230 @ 2.66GHz, 8 GB RAM, running Ferora 12
• Windows 2008 server Makes MS Windows Applications available from any worksatation including all Office Apps and Windows versions of R, Matlab and Mathematica

File Systems

1. User home directories are common for all servers. Home directories are backed up nightly. The home directories are organized as follows:

/home/faculty	math department faculty
/home/grads	math department graduate students
/home/students	undergraduate students and classes
/home/guests	all others

The physical location and amount of disk space is subject to change, but any changes should be completely transparent to users. Please delete unnecessary files - CCM disks are NOT the place to keep digitized holiday pictures or hundreds of MB of Internet loot! We run disk quotas, type "quota" to see your usage. Quotas will be increased upon request.

2. Additional disk space for temporary storage is available in /tmp Files not changed for 14 days may be deleted automatically. NOTE: Any such disk space outside of users' home directories is NOT BACKED UP and files may DISAPPEAR WITHOUT WARNING ANY TIME! Users should keep valuable files ONLY in their home directories. NOTE: Filling /tmp generally makes a machine unusable, so please be gentle.

Workstations

Eight Workstation Computers equiped with 30" monitors in the 647 CCM lab allow login directly to our Linux and Windows servers. There is also one Workstation with dual 30" monitors connected directly to one of the servers. This is intended for high performance graphics applications There are also four Workstation Computers with 24" monitors available in the hallway opposite room 635. Workstations are also availavle in graduate student offices where requested; these work just like the workstations in 647.

Printers

• xeroxbw a Phaser 5500DN is the default printer. This is our fastest printer (50 page per minute).
• ccm HP 8100dn laserjet.
• color1 is a Xerox Phaser 860DP.
• color2 is a HP4500dn laserjet.
• color3 is the newest color printer it is a Xerox Phaser 6360DN.

Wireless Networking

We have wireless networking available with good coverage on the sixth floor. This allows secure access to printers and servers and access to the internet for laptop users equipped with wireless cards or capability.
