Negative Scalability Coefficients in Excel

Recently, several performance engineers, who have been applying my universal scalability law (USL) to their throughput measurements, reported a problem whereby their Excel spreadsheet calculations produced a negative value for the coherency parameter (...

How to Recover the Missing X(1) for the USL Scalability Model

When it comes to assessing application scalability, controlled measurements of the type that can be obtained with tools like Grinder or LoadRunner, are very useful because they provide a direct measurement of the throughput, X(N), as a function of the...

Where is all the Open Source computer algebra software?

For a long time I have been puzzled by the apparent lack of a comprehensive Open Source computer algebra software, i.e. what Octave is to MatLab and what R is to S. In other words, where is the Open Source … Continue reading →
