The J. H. Wilkinson Prize for Numerical Software is awarded every four years to honor outstanding contributions in the field of numerical software. The award is named to commemorate the outstanding contributions of James H. Wilkinson in the same field. [1]

The award, consisting of $US3000 and a trophy, is jointly presented every four years by the Argonne National Laboratory, the National Physical Laboratory and the Numerical Algorithms Group.[citation needed]

Eligibility and selection criteria[edit]

The winner must be at most 40 years of age as of January 1 of the year of the award. The award is given on the basis of:

  • Clarity of the software implementation and documentation.
  • Clarity of the paper accompanying the entry.
  • Portability, reliability, efficiency and usability of the software implementation.
  • Depth of analysis of the algorithm and the software.
  • Importance of application addressed by the software.
  • Quality of the test software[citation needed]



The first prize in 1991 was awarded to Linda Petzold for DASSL, a differential algebraic equation solver. This code is available in the public domain.[2]


The 1995 prize was awarded to Chris Bischof and Alan Carle for ADIFOR 2.0, an automatic differentiation tool for Fortran 77 programs. The code is available for educational and non-profit research.[3]


The 1999 prize was awarded to Matteo Frigo and Steven G. Johnson for FFTW, a C library for computing the discrete Fourier transform.


The 2003 prize was awarded to Jonathan Shewchuk for Triangle, a two-dimensional mesh generator and Delaunay Triangulator. It is freely available.[4]


The 2007 prize was awarded to Wolfgang Bangerth, Guido Kanschat, and Ralf Hartmann for deal.II, a software library for computational solution of partial differential equations using adaptive finite elements. It is freely available.[5]


Andreas Waechter (IBM T. J. Watson Research Center) and Carl Laird (Texas A&M University) were awarded the 2011 prize for IPOPT, an object-oriented library for solving large-scale continuous optimization problems. It is freely available.[6]


The 2015 prize was awarded to Patrick Farrell (University of Oxford), Simon Funke (Simula Research Laboratory), David Ham (Imperial College London), and Marie Rognes (Simula Research Laboratory) for the development of dolfin-adjoint, a package which automatically derives and solves adjoint and tangent linear equations from high-level mathematical specifications of finite element discretisations of partial differential equations.[7]
