libCL is an open-source library for high performance computing in OpenCL. Rather than a specific domain, libCL intends to encompass a wide range of parallel algorithms. The goal is to provide a comprehensive repository of kernels and data structures for visual-centric computing ranging from fundamental primitives such as sorting, searching and algebra to advanced systems of algorithms for computational research and visualization.

libCL provides a core set of C++ classes that encapsulate the OpenCL API and provide a simple error handling and logging infrastructure. Based upon this core functionality are implementations of specific algorithms categorized within different subdirectories:
