Research Computing and Cyberinfrastructure
Provide systems services by researching current practices in operating system, file system,
data storage, job scheduling as well as computational support related to compilers, parallel
computations, libraries, and other software support. Also supports visualization of large
datasets by innovative means to gain better insight from the results of simulations.
Enable large-scale computations and data management by building and operating several
state-of-the art computational clusters and machines with a variety of architectures.
Consolidate and thus significantly increase the research computing resources available to
each faculty participant. Faculty members can frequently exceed their share of the machine to
meet peak computing needs
Provide support and expertise for using programming languages, libraries, and specialized
data and software for several disciplines.
Investigate emerging visual computing technologies and implement leading-edge solutions in
a cost-effective manner to help faculty better integrate data visualization tools and immersive
facilities in their research and instruction.
Investigate emerging architectures for numerically-intensive computations and work with
early-stage companies. For example: interconnects, networking, and graphics processors and
FPGA for computations.
Help build inter- and intra-institutional research communities using cyberinfrastructure and
grid technologies.
Maintain close contacts with NSF and DoE funded national centers, and help faculty members
with porting and scaling of codes across multiple architectures.

" ... to out-compete, we must out-compute .... "
• Putting Pennsylvania based companies at a competitive advantage by
helping meet their large-scale computing needs.
Many small-to-medium sized companies, and even larger ones, do not
have enough
in-house expertise and resources for large-scale
computations and as a result have not been able to use simulation and
analysis tools with far greater frequency to help them innovate faster and
become more competitive.
• Helping develop stronger relationship between faculty and industry by
providing computational services; may lead to more alignment between
faculty research areas and industry needs and positive impact on
economic development along the I-99 corridor and throughout the
