Software
Developed in-house and maintained
The following is a list of software and numerical libraries developed and maintained in-house by the SLQM team.
Numerical linear algebra libraries (JuNLib)
- ChASE: Chebyshev Accelerated Subspace iteration Eigensolver.
It is a modern interpretation of the original algorithm proposed by Rutishauser in 1969. The library contains algorithmic improvements, such as an optimization scheme for the polynomial degree and a precise estimate for the filter bounds, and targets modern heterogeneous computing platforms.
Contact: E. Di Napoli - PAID: Parallel Adaptive Integration in multiple Dimensions.
Library for adaptive integration based on Clenshaw-Curtis method parallelized for shared memory platforms.
Contact: J. Winkelmann SMG2S (Scalable Matrix Generator with Given Spectrum)
SMG2S is a software which provides generator for the non-Symmetric and non-Hermitian sparse matrices with eigenvalues given by users. It is proposed to benchmark and analyse the impacts of the spectral distribution of systems on the behaviours of parallel iterative eigen-solvers and linear-solvers. SMG2S is implemented in parallel based on MPI and C++11 with good parallel efficiency. (Code)

Simulation Software
- KKRnano as part of juKKR
A simulation code based on the Korringa-Kohn-Rostoker formalism tailored to nanoelectronic simulations which scales linearly with the number of atoms. The tfQMRgpu library allows to solve the Dyson equation on NVIDIA GPUs.
Contact: P. Baumeister - juRS: The Jülich Real-Space code.
Density Functional Theory code based on real-space discretization grid which uses hybrid parallelism and Blöchl’s PAW formalism to get full potential accuracy.
Contact: P. Baumeister - 1D-NEGF.
Non-Equilibrium Green's Functions for transport phenomena.
