Accelerating analytics at MSU with Revolution R Enterprise
Updated: 2012-02-03 19:55:12Erik Sigur, Information Technologist for the Department of Statistics and Probability at Michigan State University, writes at ReadWriteWeb about using Revolution R Enterprise to provide high-performance computation in R to the researchers in his department: Our search for a more effective version of R ultimately brought us to a product called Revolution R Enterprise by Revolution Analytics, which provides commercial support and software for open source R. It takes advantage of multiple processor cores by using optimized assembly code and efficient multi-threaded algorithms that use all of the processor cores simultaneously. The department at MSU provides high-performance computing facilities via...speed of R, C, &tc.
Updated: 2012-02-02 23:12:45My Paris colleague (and fellow-runner) Aurélien Garivier has produced an interesting comparison of 4 (or 6 if you consider scilab and octave as different from matlab) computer languages in terms of speed for producing the MLE in a hidden Markov model, using EM and the Baum-Welch algorithms. His conclusions are that matlab is a lot [...]C and a Box of Chocolates: Video Presentations from the Wolfram Technology Conference 2011
Updated: 2012-01-25 19:27:08Tips for analyzing your social networks with Mathematica, workshops for publishing with CDF, real-world solutions for your financial applications—these are just a few of the many highlights from the Wolfram Technology Conference 2011. If you missed a talk or weren't able to attend, we've now made videos of select presentations available ...Recent Data For Planning Mathematical Software Projects

Updated: 2012-01-13 21:33:43If you have small children, especially in daycare, eventually you will be exposed to a wide variety of illnesses. One of the least fun is viral gastroenteritis caused by norovirus. Norovirus is not susceptible to alcohol hand sanitizers due to its durable protein coat, and the main method for sanitizing surfaces that have been exposed [...]Estimating the Cost and Schedule of Mathematical Software
