TACC is now accepting applications for the 2015 Research Experience for Undergraduates (REU) from June 1 to August 1, 2015. This summer, 10 undergraduate students from across the United States majoring in science and engineering will be immersed in training at UT Austin to become the next generation of ‘game changers.' Participants will explore grand challenges including … [Read more...]
Kriging Interpolation Exhibits Strong Scaling Across GPUs
Geostatistical interpolation (Kriging) can be useful in a great number of applications where high fidelity models are required for mapping spatial effects and making predictions based on observations. It is widely utilized in the domain of spatial analysis and computer experiments and heavily used by the US Air Force and GIS services. The following images by Yang, et. al. … [Read more...]

Sparse matrix-vector multiplication: parallelization and vectorization
The chapter authors (Albert-Jan N. Yzelman, Dirk Roose, and Karl Meerbergen) note that, "Current hardware trends lead to an increasing width of vector units as well as to decreasing effective bandwidth-per-core. For sparse computations these two trends conflict.” For this reason they designed a usable and efficient data structure for vectorized sparse computations on … [Read more...]
Heterogeneous MPI Optimization With ITAC
This chapter focuses on the workload balance of MPI applications running in heterogeneous cluster environment consisting of Intel Xeon processors and Intel Xeon Phi coprocessors in a financial industry application that calculates Asian option payoffs. Three cases are considered: unbalanced symmetric MPI code, manual balancing with pre-calculated performances of the cluster … [Read more...]
Profiling Guided Optimization On Intel Xeon Phi
This chapter in High Performance Parallelism Pearls by Andrey Vladimirov focuses on the use of Intel VTune Amplifier XE reports to understand where to apply optimization on matrix transposition, a small and self-contained workload of great practical value. The optimization process applied to the code relies exclusively on programming in a high-level language plus utilization of … [Read more...]
