Computational Facilities:

The chemistry modeling lab is equipped with 12 Windows PC's running Gaussianand GaussView. Additional Apple computers provide support for student-based research or teaching needs.

The computational chemistry group features a variety of workstations for individual tasks, including several 12-core Linux workstations and a 40-coreSGI Altix compute server with Infiniband high-speed interconnectivity. Additional Apple computer support graphics and presentation needs.

The UTA High-Performance Computation (HPC) Center currently consists of about 1,000 processor-cores with more than 90 terabytes of aggregate storage. HPC Center's computational nodes utilize state-of-the-art technology (currently IntelCore i7, Nehalem) and Red Hat Enterprise Linux as an operating environment This cluster is dedicated to computational research, and open to faculty and staff. Students get access via class accounts or via their research supervisor. The HPC Center has installed several software packages, notably for chemists this includes the Gaussian09 suite.

Being part of the UT System, faculty members have easy (non-proposal) access to resources provided by the Texas Advanced Computing Center (TACC) at UT Austin. This includes accounts on the super-computers Stampede and Lonestar, access to high-throughput graphical workstations, and mass-storage facilities.

Miscellaneous Resources:

DNA sequencing and additional biological/biochemical facilities
are available at the Life Science Core Facility

Shimadzu Center for Advanced Analytical Chemistry (http://www.uta.edu/scaac/)

The Chemistry Department at UTA maintains a Cryomech LHe18 helium plant for recycling LHe to support departmental magnetic resonance facilities.

Within the department, there is a well-equipped machine shop, two electronics shops, and a well-equipped stockroom; all maintained and run by our dedicated staff members. The University Library has over 1.1 million volumes, 87,500 of which are in the Science and Engineering Library, which is in close proximity to the department in Nedderman Hall.
