Nonnegative Matrix Factorization (NMF) is a dimension reduction method that has been widely used for various tasks including text mining, pattern analysis, clustering, and cancer ...
In this paper, we design linear time algorithms to recognize and determine topological invariants such as genus and homology groups in 3D. These invariants can be used to identify...
This paper presents an extensive characterization, tuning, and optimization of parallel I/O on the Cray XT supercomputer, named Jaguar, at Oak Ridge National Laboratory. We have c...
We present an auto-tuning approach to optimize application performance on emerging multicore architectures. The methodology extends the idea of searchbased performance optimizatio...

As the number of cores per die increases, be they processors, memory blocks, or custom accelerators, the on-chip interconnect the cores use to communicate gains importance. We beg...
