Numerical Algorithms Group wrote a new blog post titled Secrets of HPC Procurement

Liked my article today in HPC Wire "Secrets of the Supercomputers"? I firmly poke fun at various elements of an imaginary supercomputer procurement process. However, I'm sure many readers will also see familiar and painfully serious aspects in the fictional story. As I mention at the bottom of that article, NAG can help make the process of buying HPC systems much better than the worrying case in the article. For example, the tutorial I ran at SC13 with Terry Hewitt titled "Effective Procurement of HPC Systems" was very popular (~100 attendees). We have provided similar training as part of...

Numerical Algorithms Group wrote a new blog post titled Testing Matrix Function Algorithms Using Identities

Edvin Deadman and Nick Higham (University of Manchester) write: In a previous blog post we explained how testing new algorithms is difficult. We discussed the forward error (how far from the actual solution are we?) and the backward error (what problem have we actually solved?) and how we'd like the backward error to be close to the unit roundoff, u. For matrix functions, we also mentioned the idea of using identities such as sin2A + cos2A = I to test algorithms. In practice, rather than I, we might find that we obtain a matrix R close to I, perhaps with ||R-I||...

Numerical Algorithms Group wrote a new blog post titled The Wilkinson Prize for Numerical Software

In honour of the outstanding contributions of James Hardy Wilkinson to the field of numerical software, Argonne National Laboratory, the National Physical Laboratory, and the Numerical Algorithms Group award the Wilkinson Prize for Numerical Software (US $3000). The 2015 prize will be awarded at the International Conference in Industrial and Applied Mathematics (ICIAM) in Beijing, China, August 2015. Entries must be received by July 1, 2014. Additional details on the Wilkinson Prize for Numerical Software and the official rules canbe found at the...
