Key-Value Tree (KVTree) Library

The Key-Value Tree (KVTree) library provides a fully extensible C data structure modeled after Perl hashes.

KVTree was originally part of the SCR Library.

Details on the library can be found in the User API docs.

Quickstart

KVTree uses the CMake build system and we recommend out-of-source builds.

git clone git@github.com:llnl/kvtree.git
mkdir build
mkdir install

cd build
cmake -DCMAKE_INSTALL_PREFIX=../install ../KVTree
make
make install
make test

Some useful CMake command line options:

• -DCMAKE_INSTALL_PREFIX=[path]: Place to install the KVTree library
• -DCMAKE_BUILD_TYPE=[Debug/Release]: Build with debugging or optimizations
• -DMPI: Build with support for MPI movement of kvtree objects

Dependencies

• C
• MPI (optional)
• CMake, Version 3.14+
