Our current computational servers consists of a Dell R920 Linux server running RedHat, this server is configured with 4 8-core 64-bit CPUs for a total of 32 cores and 256GB of RAM. These systems are configured with STATA/SE, STATA-MP, SAS, Matlab, R, Stat/Transfer, and other research software.
The PSTC has approximately 50 Dell workstations running Windows 7 64-bit in Mencoff Hall. The computers are all new dual core processors with at least 4 GB of memory and flat panel monitors. Faculty PCs all have quad core processors, with at least 8GB of memory and 1TB hard drives. Each student workspace and faculty or staff office is equipped with its own computer. The PSTC also has a computer lab with eight computers available for use by any member of the PSTC community.
The PSTC uses an Active Directory Domain running Windows server 2008 R2 for authentication and security via group policy. These servers also monitor printer usage and are backed up nightly.
Printing and Scanning

Additional software is available through Brown CIS and can be installed on any Brown-owned computer. A complete listing is available on the CIS Software Distribution Web site. For assistance installing any of this software, e-mail Paul Koussa.
Programming and statistical services are also offered by the PSTC to affiliated faculty and students. The PSTC's research analyst/programmer provides statistical consultation and non-spatial programming services. The programmer works with project teams to assemble, link, and analyze multi-layered, complex data sets to suit diverse research objectives using state-of-the-art computational/statistical software programs. This work includes reconciling questionnaire data across rounds with extensive subsetting of samples, matching across datasets that may have been collected at different levels, and accurately interpreting complex skip patterns. Other services include producing data files, analysis, and reports to project teams, training in statistical software packages, and walk-in and scheduled consultations.
Spatial analysis is provided by Spatial Structures in the Social Sciences (S4) and is described in detail on the Spatial Analysis services web page. The S4 facility in Maxcy Hall has 12 offices that provide space for three faculty, four staff, and eight post-docs or graduate students, each with a dedicated PC that can access the Mencoff Hall computer services.
