A page to summarise and coordinate SAGE development activity.
Core arithmetic team
David Harvey, Martin Albrecht, Joel Mohler, Robert Bradshaw, William Stein
Develop new __mul__ semantics for rings/algebras using something like ToyQuarternionAlgebraElement as a test case.
Migrate _add_, _mul_ etc to new _add_sibling, _add_sibling_cdef, framework etc. Intention is to eventually remove _add_ everywhere.
Change all __add__ methods (etc) to use new fast code pathways, pyrex tricks, as studied at SAGE Days 2.
Try changing a.parent() == b.parent() conditions to a._parent is b._parent in various places and see what breaks.
Write up more entries in WritingFastPyrexCode. (everyone)
- Write a benchmarking module.
- Optimise pyrex in coercion module.
Make Algebra _base_ring into a cdef attribute.
Move univariate Polynomial class down to Pyrex, and make it inherit from CommutativeAlgebra instead of CommutativeRing. (David)
Rewrite polynomials over Z and Z/nZ using direct NTL calls. (David)
- Optimise new integers mod n code using fast pyrex tricks.
- Wrap NTL finite fields and polynomials over finite fields.
Benchmark omalloc. (Martin)
- Linear algebra (perhaps William or Robert want to say something here?)
Making SAGE Releases (Packaging and Integration)
- William Stein
- Getting sage-1.4.1 ready:
- New maxima, pari, clisp.
- Editing and including axiom interface.
Lower priority issues
- Make generic dense polynomial class in pyrex using C arrays to store coefficients?
