| [Nextflow](https://www.nextflow.io) | Nextflow is a reactive workflow framework and a programming DSL that eases writing computational pipelines with complex data |
| [Ninja](https://ninja-build.org/) | Ninja is a small build system with a focus on speed. |
| [numactl](https://github.com/numactl/numactl) | The numactl program allows you to run your application program on specific cpu's and memory nodes. It does this by supplying a NUMA memory policy to the operating system before running your program. The libnuma library provides convenient ways for you to add NUMA memory policies into your own program. |
| [openPMD-api](https://github.com/openPMD/openPMD-api) | openPMD is an open meta-data schema that provides meaning and self-description for data sets in science and engineering. See the openPMD standard for details of this schema. This library provides a reference API for openPMD data handling. Since openPMD is a schema (or markup) on top of portable, hierarchical file formats, this library implements various backends such as HDF5, ADIOS2 and JSON. Writing & reading through those backends and their associated files are supported for serial and MPI-parallel workflows. |
| [optking](https://github.com/psi-rking/optking) | optking (also known as pyoptking) is a rewrite of the c++ optking module in psi4. This rewrite was undertaken to enable future development and for use with recent interoperability efforts (e.g. MolSSI QCArchive and QCDB). optking is focused on optimization of molecular geometries: finding minima, transition states, and reaction paths. Current work is focused especially on expanding the reaction path methods. |
| [parallel](https://savannah.gnu.org/projects/parallel/) | parallel: Build and execute shell commands in parallel |
| Particleworks | Old module, description not available. |
