K-Means for Parallel Architectures Using All-Prefix-Sum Sorting and Updating Steps
Found in: IEEE Transactions on Parallel and Distributed Systems
By Kai J. Kohlhoff,Vijay S. Pande,Russ B. Altman
Issue Date:August 2013
pp. 1602-1612
We present an implementation of parallel $(K)$-means clustering, called $(K_{ps})$-means, that achieves high performance with near-full occupancy compute kernels without imposing limits on the number of dimensions and data points permitted as input, thus c...
Science in the Cloud: Accelerating Discovery in the 21st Century
Found in: IEEE Internet Computing
By Joseph L. Hellerstein,Kai J. Kohlhoff,David E. Konerding
Issue Date:July 2012
pp. 64-68
Scientific discovery is transitioning from a focus on data collection to an emphasis on analysis and prediction using large-scale computation. With appropriate software support, scientists can do these computations with unused cycles in commercial clouds. ...
