“…PROOF [3], Parallel ROOT Facility, is a special ROOT tool that uses natural parallelism of data structures located in files of a special format and providing direct access to any individual value. In our previous work [4], we compared the efficiency of data processing using PROOF and a special class for threading, as well as the OpenMP technology. It showed the high performance of PROOF, if the analysis contained a large number of mathematical operations and was performed on a large amount of data.…”

The ROOT software package is currently being upgraded in several ways to improve data processingperformance. This paper will consider several tools implemented in this framework for calculations onmodern heterogeneous computing architectures. PROOF (Parallel ROOT Package Extension) dividescommon work into small chunks, i.e. packets. The size of the first packet used for calibration, theminimum and maximum set size of the packet, the degree of data structuring affect the speed of theirprocessing. When processing large amounts of data, the read and write speed can be crucial. The newasynchronous file merge feature in the TBufferMerger class allows writing data in parallel frommultiple streams to a single output file. Our calculations show a good scalability of the macroexecution time depending on the number of processor cores used.
