MPIR - Parallel Algorithms and CUDA

Present : Carl Witty, Bill Hart, Michael Abshoff, Glenn Tarbox Virtually Present : Jeff Gilchrist, Gonzalo Tornaria

You can chat in a Linux text console by installing "irssi" and running: "irssi -c irc.freenode.net" and then type "/join #sage-devel"

Parallel algorithms:

• Multimodular algorithms
• Scalar algorithms

• Peter Montgomery's remainder algorithm a mod b, precompute b1 = B mod b, b2 = B^{2 mod b, b3 = B}3 mod b, then write a = a0 + a1*B + a2*B^2 +..., then compute a0 + a1*b1 + a2*b2 +.... and do final reduction mod b. Multiplications can be done in parallel.

• Addition and subtraction can be parallelised using nails - non-unique representation of numbers

Glenn Tarbox (Owner of cuda1, AMD K10 with NVIDA CUDA card - expert on large scale parallelisation)

• What are the top level integration issues, e.g. by libraries using MPIR

Michael Abshoff (Sage release manager)

• Link into Sage via cython and link in CUDA
