Maciej Besta, a PhD student in the Scalable Parallel Computing Lab led by Professor Torsten Hoefler at ETH Zurich, won recognition for his project, "Accelerating Large-Scale Distributed Graph Computations." During first year as a PhD student, Besta successfully completed several projects related to various HPC subdomains, which secured Besta the first Google European Doctoral Fellowship in Parallel Computing.
Besta's research interests focus on improving the performance of large-scale graph processing in both traditional scientific domains and in the emerging big data computations. Besta and his advisor also collaborate with researchers from the Georgia institute of Technology on designing a novel on-chip topology for future massively parallel manycore architectures that improves the performance of network traffic patterns present in graph processing workloads.
Dhairya Malhotra, a PhD student at the University of Texas at Austin actively working in the field of high performance computing, won recognition for his project, "Scalable Algorithms for Evaluating Volume Potentials." As an undergraduate intern, Malhotra was part of the group that won the 2010 ACM Gordon Bell Prize for "Petascale Direct Numerical Simulation of Blood Flow on 200K Cores and Heterogeneous Architectures," where he had implemented performance critical GPU code using CUDA.
Malhotra's research focuses on developing fast scalable solvers for elliptic PDEs such as Poisson, Stokes and Helmholtz equations. Additionally, a significant contribution of Malhotra's research has been development of the pvfmm library (Parallel Volume Fast Multipole Method) for evaluating volume potentials efficiently.
