The LvArray project is a collection of array classes for use in high-performance simulation software. LvArray provides:

1. Multi-dimensional arrays with permutable data layout.
2. Sorted Arrays are similar to std::set but are contiguous in memory.
3. ArrayOfArrays provide a 2-dimensional array with variable sized second dimension.
4. ArrayOfSets provide a 2-dimensional array with variable sized second dimension that are sorted.
5. CRSMatrix for storage of sparse matricies.

All components of LvArray provide smart management of data motion between memory spaces on systems with hetergeneous memory (e.g. CPU/GPU) through lambda copy semantics in RAJA, similar to the implementation of the CHAI::ManagedArray
