Realtime (de)compression
The goal of this project is to study the performance and effectiveness of various compression algorithms, specifically on ATLAS RAW data. The ATLAS experiment produces extremely large amounts of data, and it is only expected to increase with future planned upgrades within the LHC. Prior studies into compression of the data has shown that due to the highly redundant nature of the generated data, lossless data compression algorithms are extremely effective in reducing the binary size of ATLAS data. Here, we would like to find an algorithm that has a good balance of compression time, and compressed binary size.
