Weak signal ham radio communication
The WSJT project currently includes five programs designed for amateur radio communication using state of the art digital techniques. Typical applications include meteor scatter, EME ("moonbounce"), and QRP communication at HF. Summary Program Descriptions: WSJT: Modes JTMS, FSK441, ISCAT, JT6M, JT65, JT4, Echo, CW. Optimized for meteor scanner, ionospheric scatter, and EME at VHF/UHF/Microwaves. WSJT-X: Modes JT65, JT9. Primarily for use at HF. MAP65: For EME an VHF and higher frequencies. Implements a panoramic, polarization-matching receiver for JT65. WSPR: Probe potential propagation paths using low-power transmissions. WSPR-X: Experimental version of WSPR, including the slow mode WSPR-15. Source code is maintained here SourceForge. For installable end-user packages please go to the WSJT web site at the link below.

CFD-related Fortran libraries and applications
The CFD Utility Software Library (previously known as the Aerodynamics Division Software Library at NASA Ames Research Center) contains nearly 30 libraries of generalized subroutines and close to 100 applications built upon those libraries. These utilities have accumulated during four decades or so of software development in the aerospace field. All are written in Fortran 90 or FORTRAN 77 with potential reuse in mind. The only exception is the C translations of a dozen or so numerics routines grouped as C_utilities. David Saunders and Robert Kennelly are the primary authors, but miscellaneous contributions by others are gratefully acknowledged. See 1-line summaries of the libraries and applications under the Files menu. Each library folder also contains 1-line summaries of the grouped subroutines, while each application folder contains READMEs adapted from the main program headers. NASA permission to upload actual software was granted on Jan. 24, 2014.

Cellular Automata library for SUPercomputers (CASUP)
CASUP is a Cellular Automata (CA) library for HPC and supercomputers. It can be used in materials science (microstructure evolution, grain coarsening, fracture etc.), physics (Ising magnetisation) and for many other CA. If you use the library, please reference it as: A. Shterenlikht, L. Margetts, Three-dimensional cellular automata modelling of cleavage propagation across crystal boundaries in polycrystalline microstructures, Proc. Roy. Soc. A 471:20150039, DOI: http://dx.doi.org/10.1098/rspa.2015.0039. CASUP can be linked with FE (e.g. MPI FE library ParaFEM, http://parafem.org.uk) for a multi-scale multi-physics CA-FE framework. CASUP extensively uses Fortran 2008 and 2018 coarrays, as well as MPI, OpenMP and do concurrent. CASUP can be used with Cray, Intel and GCC/OpenCoarrays compilers. Scaling beyond 100,000 cores on Cray XC30 was demonstrated.
