Increasing the functionality of the modern NoSQL-systems with GPGPU-technology

The object of research is a distributed database management system Apache Cassandra and methods to improve its functionality by applying hybrid computing technologies. The encryption standard GOST 28147-89, which has a great potential for parallelization on the graphics core and can be used as the expansion module. Development was carried out in the Java language using the open source project Apache Cassandra and JCuda parallelization library for GPGPU systems. The article contains analysis of the Apache Cassandra architectural features and review of possibilities for connecting the expansion modules. The article presents a mathematical model of the proposed solution and experimental results (graphs of recording data rate to the base: in the standard mode, with using CPU encryption, with using GPU encryption).
