Schurcheb is a MPI-based parallel library for computing partial spectral factorizations of matrix pencils via Chebyshev approximation. The library returns those eigenvalues (and corresponding eigenvectors) of symmetric matrix pencils that lie within a target interval.
ParGeMSLR (MPI/C++)
ParGeMSLR is a MPI-based parallel library for the solution of sparse linear systems. It is based on algebraic domain decomposition and combines ideas from block-Jacobi preconditioners and low-rank corrections.
Cucheb (CUDA)
The Cucheb library is a CUDA implementation of the filtered Lanczos procedure for the solution of sparse Hermitian eigenvalue problems on NVIDIA GPUs.
EigenRec (Fortran90/MPI)
The EigenRec library is a Fortran 90 implementation of a Lanczos-based, latent factor framework for Top-N recommendations. EigenRec is designed for distributed memory computing environments.
PP-BCG (Fortran90/MPI)
The Parallel Projection Block Conjugate Gradient (PP-BCG) library is a Fortran 90 implementation of an accelerated block Conjugate Gradient scheme for the solution of SPD dense linear systems with multiple right-hand sides. PP-BCG targets distributed memory computing environments and has been successfully tested on up to four BG/Q racks (65,536 cores).
TeraPCA (C++)
TeraPCA is a multithreaded C++ software suite based on Intel's MKL library (or any other BLAS and/or LAPACK distribution) that aims on computing the leading Principal Components of large-scale datasets that can not fully reside on the system memory. TeraPCA features no dependencies to external libraries and combines the robustness of subspace iteration with the power of randomization.
