zfp is a compressed number format for multi-dimensional arrays. zfp provides compressed-array classes (e.g., for in-memory storage) and high-speed, parallel data compression (e.g., for offline storage). zfp supports both lossy and lossless compression and fine-grained user control over accuracy and storage size.

CHAI is a C++ libary providing an array object that can be used transparently in multiple memory spaces. Data is automatically migrated based on copy-construction, allowing for correct data access regardless of location. CHAI can be used standalone, but is best when paired with the RAJA library, which has built-in CHAI integration that takes care of everything.

Inja is a template engine for modern C++, loosely inspired by jinja for Python. It has an easy and yet powerful template syntax with all variables, loops, conditions, includes, callbacks, and comments you need, nested and combined as you like.

This package provides an easy to use, powerful and expressive command line argument handling library for C++11/14/17 contained in a single header file.

intervalset is a C++ library to manage sets of closed intervals of integers. This is a simple wrapper around Boost.Icl.

PDI supports loose coupling of simulation codes with data handling the simulation code is annotated in a library-agnostic way, libraries are used from the specification tree.

SciTokens provide a token format for distributed authorization. The tokens are self-describing, can be verified in a distributed fashion (no need to contact the issuer to determine if the token is valid). This is convenient for a federated environment where several otherwise-independent storage endpoints want to delegate trust for an issuer for managing a storage allocation.

Header only, fully template based library which enables accessing private data members. Techniques used by this library to achieve its purpose are fully legal and allowed by the standard. The library is based on Explicit instantiation of class template instantion.

DDC, is a C++-20 library that aims to offer to the C++/MPI world an equivalent to the xarray.DataArray/dask.Array Python environment. Where these two libraries are based on numpy, DDC relies on Kokkos and mdspan to offer CPU/GPU performance-portable multi-dimensional arrays and iterators.

howardhinnant-date extends <chrono> to calendars and timezones, focusing on a seamless integration with the existing <chrono> library, type safety, performance and ease of use.

Simple, fast, accurate single-header microbenchmarking functionality for C++11/14/17/20.

RAJA offers portable, parallel loop execution by providing building blocks that extend the generally-accepted parallel for idiom. RAJA relies on standard C++14 features.

cpp-docopt helps you:

• define the interface for your command-line app, and

• automatically generate a parser for it.

cpp-docopt is based on conventions that have been used for decades in help messages and man pages for describing a program's interface.

CAMP collects a variety of macros and metaprogramming facilities for C++ projects. It's in the direction of projects like metal (a major influence) but with a focus on wide compiler compatibility across HPC-oriented systems.

Decl'HDF5 plugin enables one to read and write data from HDF5 files in a declarative way. Decl'HDF5 does not support the full HDF5 feature set but offers a simple declarative interface to access a large subset of it for the PDI library.

This package aims to provide a production-quality implementation of the ISO-C++ proposal P0009, which will add support for non-owning multi-dimensional array references to the C++ standard library.
