Optimization of pattern-matching compression algorithms for GPU’s OPAC

Project: Optimization of pattern-matching compression algorithms for GPU’s

Acronym: OPAC

Main Objective: The main goal of the project was to study the usage of parallel hardware platforms and software stacks (CUDA, OpenCL) to speed up the execution of recurrent pattern matching-based compression algorithms. The hardware platforms include off the shelves desktop machines, multi-core CPUs, System on a Chip (SoC) and many-core Graphic Processing Units (GPUs).
