OIT offers a spectrum of services in support of high performance computing (HPC) capabilities for Georgia Tech academic units, research groups, faculty, students, and staff. Research in a wide variety of science and engineering disciplines increasingly relies on the rapidly growing capabilities of HPC as a key enabler of inquiry and discovery. The explosion of interest in the use of computation clusters - which utilize a collection of commodity computers as a computation resource - presents challenges in a numbers of areas, including security, systems administration, computation middleware, compilers, user support, networking, disk storage and backup, HVAC, power, space, hardware configuration and troubleshooting, procurement, and efficient sharing of resources.
OIT has established the Public Access Cluster Environment (PACE) initiative, which seeks to address each of these challenges in a coordinated and efficient manner, making the power of HPC more widely and cost-effectively available to all members of the Georgia Tech research community. It is especially targeted to provide the level of specialized hosting, services, and skills necessary to effectively deploy and utilize cluster computing. PACE currently supports approximately 4,000 high performance CPU cores for campus clients, including research programs in Physics, Chemical and Biochemical Engineering, Mechanical Engineering, Biology, and Earth and Atmospheric Sciences.
The PACE Community Cluster (PACE-CC) is a medium-sized computation cluster (approximately 200 CPU cores) formed with joint OIT, industry, and faculty collaboration and funding. Utilizing shared network, software, support, storage, and backup infrastructure, it is generally available as a computation and instructional resource. PACE-CC allows HPC researchers to evaluate various technologies and software before purchase, to have a place to work if waiting for dedicated machines that are on order, and to share resources with other researchers when desired.
