The Block Locally Optimal Preconditioned Eigenvalue Xolvers (BLOPEX) (Knyazev et al., 2007) is a suite of routines for the scalable (parallel) solution of eigenvalue problems. Its object-oriented design allows easy portability. Currently available built-in interfaces are Hypre, PETSc, MATLAB, GNU Octave, and a serial stand-alone version. BLOPEX supports real and complex arithmetic, and long integers. The current version is double-precision. The single-precision is not yet supported. Hypre and PETSc interfaces use the Message Passing Interface (MPI) standard for all message-passing communication. The most recent stable version of BLOPEX is 1.1, released in 2010.

SLEPc and PHAML have interfaces to call BLOPEX eigensolvers. DevTools includes some BLOPEX code.
