10 trillion digits of pi: A case study of summing hypergeometric series to high precision on multicore systems (2011-11-11)Hypergeometric series are powerful mathematical tools with many usages. Many mathematical functions, such as trigonometric functions, can be partly or entirely expressed in terms of them. In most cases this allows efficient ...
(2013-12-04)Topic modeling algorithms (like Latent Dirichlet Allocation) tend to be very slow when run over large document collections. In this presentation, we discuss distributed strategies for topic modeling. We use Charm++ as our ...
(2009-08-18)High performance, massively-parallel multi-physics simulations are built on efficient mesh data structures. Most data structures are designed from the bottom up, focusing on the implementation of linear algebra routines. ...
(2009-05-15)The shift of the microprocessor industry towards multicore architectures has placed a huge burden on the programmers by requiring explicit parallelization for performance. Implicit Parallelization is an alternative that ...
(2004-12)Current parallel programming approaches, which typically use message-passing and shared memory threads, require the programmer to write considerable low-level work management and distribution code to partition and distribute ...
(2015-07-17)We develop scalable algorithms for two-stage stochastic program optimizations. We propose performance optimizations such as cut-window mechanism in Stage 1 and scenario clustering in Stage 2 of benders method for solving ...
(2009-09-22)The k-D tree is a well-studied acceleration data structure for ray tracing. It is used to organize primitives in a scene to allow efficient execution of intersection operations between rays and the primitives. The highest ...
(2015-01-21)Power and energy efficiency are important challenges for the High Performance Computing (HPC) community. Excessive power consumption is a main limitation for further scaling of HPC systems, and researchers believe that ...
