Texas Test Problem Server


The Texas Test Problem Server is your source for complicated linear systems to be used in numerical linear algebra, graph theory, and/or performance evaluation/optimization research. The server hosts a number of applications that can be controlled through a web interface to deliver problems as large, complicated, and varied as desired.


  • Matrices from high order finite elements
  • Irregular domains
  • Local refinement
  • Unassembled matrices
  • Problems with right hand side and analytical solution
  • Non-linear and time-evolving problems
