Aestel
Applications for data management
"Information is data in action", and, consequently, having good quality data is essential. The AESTEL package contains two highly configurable applications for data management: A data loader and a reporting application, i.e. DataLoader and AEREA, respectively. The data loader application applies user-defined instructions to validate, process and load data. The reporting application provides a query builder and spreadsheet template designer. Both applications work with any relational data... -

TheoDORE
Theoretical Density, Orbital Relaxation and Exciton analysis
...Wavefunction analysis is based on state and transition density matrices, which provides a unified formalism applicable independent of the wavefunction model. TheoDORE is interfaced to a number of quantum chemical programs (Q-Chem, Columbus, Turbomole, ...) and can be used for a wide range of excited state methods (MR-CI, ADC, CC, TDDFT). It is written in a modular fashion to allow for an easy extension of these capabilities. Code development moved to github: https://github.com/felixplasser/theodore-qc -

Comparison of Cartesian Treecodes
Fortran code to compare particle-cluster and cluster-particle treecode
...The standard particle-cluster treecode partitions the sources into an octree and applies a far-field approximation, while a recently developed cluster-particle treecode instead partitions the targets into an octree and applies a near-field approximation. Particle-cluster is faster when N >> M, and cluster-particle is faster when M >> N. Reference: Boateng, H. A. and Krasny, R., J. Comput.
