Current Personnel


Yifeng Cui
Personal Webpage
Dr. Yifeng Cui is the founding Director of HPGeoC, and an adjunct professor at San Diego State University. He has general research interests in high performance computing, with expertise in parallelization, optimization, and performance evaluation on both massively parallel and vector machines. He is also currently a director of Intel Parallel Computing Center at SDSC. Cui earned his Ph.D. in hydrology from the University of Freiburg, Germany.


Alexander Breuer
Personal Webpage
Alexander’s research covers the entire simulation pipeline of hyperbolic solvers with emphasis on seismic simulations. This includes node-level performance leveraging SIMD-paradigms, hybrid and heterogeneous parallelization up to machine-size and co-design of numerics and large-scale optimizations. In 2014 Alexander was honored with an ACM/IEEE-CS George Michael Memorial HPC Fellowship. In addition he and his collaborators have been awarded with the PRACE ISC Award and nominated as ACM Gordon Bell finalists.
