  • The First Billion Digits of Pi

    Free Download — Why calculate so many digits of pi? According to Alexander J. Yee and Shigeru Kondo, world record holders for calculating the most digits of pi (5 billion digits), “because it’s Pi… and because we can!” Do not fret if you lack the expensive hardware, multi-terabytes of storage capacity and loads of free time to calculate the number that never ends. The Infochimps have ...
  • Sparse Matrix Collection : Sparse Matrices From a Wide Range of Applications

    Offsite — These matrices cover a wide spectrum of domains, include those arising from problems with underlying 2D or 3D geometry (such as structural engineering, computational fluid dynamics, model reduction, electromagnetics, semiconductor devices, thermodynamics, materials, acoustics, computer graphics/vision, robotics/kinematics, and other discretizations) and those that ...
  • Matrix Market

    Offsite — A visual repository of test data for use in comparative studies of algorithms for numerical linear algebra, featuring nearly 500 sparse matrices from a variety of applications, as well as matrix generation tools and services. Currently, 482 individual matrices and 25 matrix generators are available. The database now includes the entire Harwell-Boeing Sparse Matrix ...
