High Performance Applications

||
About us:The High Performance Applications group provides support for researchers at Indiana University and users of the TeraGrid. This support includes migration of code between computing platforms, profiling and optimization to improve application performance and parallelization of existing serial codes. Extended consulting is available. Send questions to hpahelp@indiana.edu. Indiana University's high performance computing and communication environment enables researchers across a wide range of academic fields to explore new paradigms in science, the arts, and education. Computing resources are available to the IU community without charge, "just like the library." University Information Technology Services provides hardware, software, networks, and support. Big Red is one of the most powerful university-owned computers in the US and one of the 50 fastest supercomputers in the world. Big Red is a distributed shared-memory cluster with a theoretical peak performance of over 20 teraflops. Quarry provides a general-purpose Unix computing environment for academic and instructional use. IU's newest supercomputer, Quarry runs Red Hat Linux, with TORQUE and Moab for job management and SoftEnv to simplify the application environment. Quarry is a seven teraflop system built from Intel processors. Quarry consists of 112 IBM HS21 Blade servers, each containing two Intel Xeon 5335 quad-core processors, 8GB of memory, a 36GB locally attached SAS disk for local scratch space, and gigabit Ethernet for system interconnects.Libra is a cluster of three IBM BladeCenters, an IBM P690 and six IBM P575s all running AIX 5.3. The Power chips in the P575s and the Blades can attain up to four floating point operations per cycle, providing extremely high throughput for scientific workloads. The Big Red and Quarry Linux clusters make up IU's primary parallel computing environment. They provide the muscle and the tools to manage the massive amounts of data associated with real-time access to scientific instrumentation across the Internet. The Research Database Complex serves researchers with large data analysis projects, and the Massive Data Storage System provides over 1.5 petabytes of nearline storage capacity. Linked by the I-Light optical fiber network directly to the Internet2 and the Global Research Network Operations Center in Indianapolis, these systems are part of a national and international infrastructure forming a bridge for collaboration between Indiana University researchers and their colleagues around the world. Indiana University has been chosen by the NSF to be one of nine member institutions of the TeraGrid. Access to Big Red, Libra and the RDC is provided to all Indiana University faculty, graduate students, and staff. Undergraduates must have an IU faculty or staff sponsor. Instructional use is limited to courses that have been approved by the Director for Research Technologies. Quarry accounts are open to all IU faculty, staff, and students, as well as affiliated researchers. To obtain an account visit the Account Management Service.
