Report: Workshop on Efficient Linear Algebra for Gröbner Basis Computations

As you may know, today is the last day of the wokshop on Efficient Linear Algebra for Gröbner Basis Computations that Christian Eder, Burcin Eröcal, Alexander Dreyer and I organised.

I have to say that I am quite pleased with how the workshop played out. We planned the whole thing to be hands on: people were strongly encouraged to work on projects, i.e., to write code preferably together, in addition to attending talks. Those who attended a Sage Days workshop in the past, will know what workshop format I am referring to.

Sage 4.8 is out

If you care about the stuff I care about (and why else would you read this blog?) you might get excited about a few changes in Sage.

Dense matrices mod n via FFLAS/FFPACK

During last weeks Sage Days 32 I worked on finishing a patch by Clément Pernet and Burcin Eröcal which switches Sage’s native matrices mod n (for ) to FFLAS/FFPACK. The purpose of this exercise was to make operations with dense matrices mod n both faster and more memory efficient (currently, Sage does a lot of copying around when calling any LinBox function). Well, we almost succeeded.
