Columbia University Information Technology (CUIT; Morningside Campus) and Columbia University Medical Center IT (CUMCIT; Health Sciences campus) maintain campus-wide high speed (10 gigabit per second) data networks, giving faculty access to local and remote computing resources via "dark fiber" connections that connect the campuses to regional, national and international research networks. An upgrade to a 1 gigabit per second connection between Morningside and the Lamont and Nevis campuses of Columbia is scheduled and is expected to be in place by Fall 2010. The University is a member of the New York State Education and Research Network (NYSERNet), through which the University connects to both the Internet2 and National Lambda Rail (NLR) national research networks as well as other national and international networks including Canarie, the Canadian research network, the Energy Sciences Network (ESNet), the US Large Hadron Collider Network (USLHCNet) and others. Columbia also participates in NYSGrid, the New York State Grid consortium.
Multiple commodity Internet connections provide an aggregate bandwidth of over 2 gigabits per second to the public Internet. A dark fiber network connection (part of the NYSERNet NYC Dark Fiber Network) is maintained between the Morningside Heights campus at 116th Street and the Health Sciences campus at the Columbia University Medical Center at 168th Street, where the Mailman School of Public Health is located.
Data center facilities include jointly managed, shared, and researcher-owned computational and storage systems.
All faculty are provided with e-mail accounts, as well as directory space for distributing files on the World Wide Web. The University's central Unix, Windows and MacOS systems support a number of mathematical and statistical packages (including Mathematica, Matlab, R, SAS, Splus, Stata, SPSS), geographic information systems (including ArcGIS, ArcView), general programming languages (including C and Perl), database systems (including an Oracle site license), and office productivity applications (through a Microsoft Campus Agreement). The Information Technology groups provide user support desks where faculty may find assistance with information technology.
