# For a library or package, you might want to ignore these files since the code is

# pipenv
# According to pypa/pipenv#598, it is recommended to include Pipfile.lock in version control.
# However, in case of collaboration, if having platform-specific dependencies or dependencies
# having no cross-platform support, pipenv may install dependencies that don't work, or not
# install all needed dependencies.
#Pipfile.lock
# poetry
# Similar to Pipfile.lock, it is generally recommended to include poetry.lock in version control.
# This is especially recommended for binary packages to ensure reproducibility, and is more
# commonly ignored for libraries.

#poetry.lock
# pdm
# Similar to Pipfile.lock, it is generally recommended to include pdm.lock in version control.
#pdm.lock
# pdm stores project-wide configurations in .pdm.toml, but it is recommended to not include it

<h1 align="center">Compression library for numerical datasets</h1>
BigWhoop is a compression library for numerical datasets that has been developed as part of the EU Projects ExaFLOW and EXCELLERAT. It aims to give scientists and egineers a tool to drastically reduce the size of their simulation data while minimizing the distortion introduced by a lossy compression scheme.
<h1 align="center">Building BigWhoop</h1>
### Dependencies
* make
* cmake (>= 3.5.1)
* gcc (>= 8.5.0)
### Building
pull the sources from HLRS' gitea instance (note: default branch is `main`):
```
git pull https://code.hlrs.de/hpcpvogl/BigWhoop.git
```
Now change into the source directory and run the following commands.
**for a simple build**
```
make clean
make
```
**for a full build (including command line tool)**
```
make full
```
**for debugging**
```
make clean
make debug
```
This builds the library and places the associated files in the `/lib` or `/lib64` folders. If a full build was attempted, the command line tool binaries are placed in the `/bin` folder.

|| DESCRIPTION: ||
|| ------------ ||
|| This file describes a set of functions that can be used to create, manipulate and terminate ||
|| a bitstream. These functions facilitate the creation or reading of a compressed bwc code- ||
|| stream and can emit/extract information on a per bit, symbol (64-bit) or string basis. ||

|| DESCRIPTION: ||
|| ------------ ||
|| This is a simple command line tool that uses the Big Whoop library to (de)com- ||
|| press a 2- to 4-dimensional IEEE 754 floating point array. For further infor- ||
|| mation use the --help (-h) argument in the command-line or consult the appro- ||
|| priate README file. ||
