We describe in this paper new design techniques used in the
C++
exact linear algebra library
LinBox
, intended to make the library safer and easier to use, while keeping it generic and efficient. First, we review the new simplified structure for containers, based on our
founding scope allocation
model. We explain design choices and their impact on coding: unification of our matrix classes, clearer model for matrices and submatrices,
etc.
Then we present a variation of the
strategy
design pattern that is comprised of a controller–plugin system: the controller (solution) chooses among plug-ins (algorithms) that always call back the controllers for subtasks. We give examples using the solution
mul
. Finally we present a benchmark architecture that serves two purposes: Providing the user with easier ways to produce graphs; Creating a framework for automatically tuning the library and supporting regression testing.
