High Performance Computing


Computational resources are a critical part of scientific research and engineering programs. These resources play an increasingly important role in preparing students for careers in both commercial and academics fields.

Recent advances in data acquisition, algorithm development, and computer hardware have made High Performance Computing (HPC) fundamentally necessary to remain competitive. The University of Memphis recognizes the importance of local HPC resources for research and education (see our current faculty and students page for resource usage details).

Starting in 2006, the University of Memphis has maintained HPC facilities on campus. Since its inception, this facility has enabled research programs spanning such disciplines as bioinformatics, engineering, physics, chemistry, mathematics and more (see our research page for details).
