Computer Services Recharge Center Information
Our faculty, staff, postdocs, affiliated researchers, and graduate and undergraduate students require a highly sophisticated computing environment and level of technical support. Through the Computer Services Recharge Center, we provide the required technical staff to provide these critical services.
This Recharge Center is reviewed by the University periodically to ensure it is in compliance with all applicable federal and state regulations, including OMB Circulars A-21 and A-110, as well as applicable University policy. Rates are adjusted annually to ensure that the Recharge Center is operating on a strict cost recovery basis. The current rate is $600.06 per Full Time Equivalent (FTE) per month. Rates apply to each user and are charged based upon each person's salary distribution, e.g., if a person works 50% on one project and 50% on another during the month, each project pays 50% of the fee for that month. All employees and students are assessed the same rate without regard to their salary source (federal, state, foundation, commercial). No additional fees are charged and all services included within the Recharge Center are available to all users.
General Computing Environment
The department's computing environment includes over 1000 computers, ranging from older systems used for isolated small projects to state-of-the-art workstations and clusters for graphics- and compute-intensive research. Departmental servers provide compute service, disk space, email, SVN (version control software), web service, database services, backups, and many other services. All systems are integrated by means of high-speed networks, described below, and are supported by a highly skilled technical staff who provide a consistent computing environment throughout the department. Each student is assigned a computer, with computer assignments based on the students' research or teaching assignments and their seniority within the department. In addition to the departmental servers and office systems, our research laboratories contain a variety of specialized equipment and facilities.
Departmental computing systems include around 750 Dell computers, 140 Lenovos, 130 IBMs, 12 Suns, 110 Macs, plus about 70 other computers.
Our systems primarily run the Windows 7 and Ubuntu operating systems, with a smaller number of systems, including many of the servers, running Solaris and FreeBSD. We use the NFS and CIFS file systems (ZFS and EXT4FS backing) for central file storage. Languages most commonly used include J++, C++, and Java. Document preparation is usually accomplished with standard applications on PC systems. Our extensive software holdings are continually evolving.
The department's computer systems are connected to one another by a high-speed data network. The network provides switched 100 megabit connections to every desktop, plus fiber, video, and multiple voice and data connections in each office. Special purpose systems and switches, as well as a number of our workstations, use gigabit connections. The campus Internet II connection is in Sitterson Hall and provides even higher speeds for applications that require it.
Services Provided by the CSRC
The Computer Science Department's Computer Services Recharge Center provides a wide variety of services for its users. Most of these services are either unavailable from ITS or only available on a fee for service basis. Even when services are available from ITS, the CSRC provides a substantially greater level of service and customization to meet the department's specialized research and education needs. Examples of services that go far beyond what is available to other campus employees are given below.
7X24 emergency support
CSRC personnel share an emergency pager and are available to handle emergencies around the clock. This may entail bringing core services and critical systems up after power outages, handling water leaks or HVAC outages, troubleshooting server problems, or responding to literally any issue that our users consider an emergency.
On-site Dell and Macintosh hardware support
Our staff coordinates wth Dell and Apple (along with other vendors) to provide on-site warranty service on Dell and Macintosh computers as well as service once the warranty runs out.
Special event support
When the department's faculty host conferences on campus, CSRC staff provide on-site technical support. This includes support for attendees connection to the our wireless network, A/V support, recording of talks, teleconferencing support, and assistance with any other conference needs.
The CSRC staff provide user data backups for departmental server systems.
CSRC staff provide support for Rice Hall conference room AV systems as well custom installation and maintenance for video projectors in faculty offices and research spaces.
The department has its own telephone switch, supported by CSRC personnel. All faculty and staff have department provided voice mail and telephones in their offices, and we also have telephones in all labs, conference rooms, and classrooms. When a user changes offices, CSRC moves the telephone number from the old office to the new, so no one's number ever changes.
