The development of SPPARKS has been funded by the US Department of Energy (DOE), through its LDRD and ASC programs.
The currrent developers of SPPARKS are John Mitchell (Sandia National Labs) and Steve Plimpton (retired from Sandia). They can be contacted at jamitch@sandia.gov and sjplimp@gmail.com respectively.
Past developers include Aidan Thompson (Sandia) and Alex Slepoy (Sandia and DOE).
