Currently open-source PostgreSQL DBMS is a reliable alternative for commercial DBMSes. There are many both practical database applications based upon PostgreSQL and research projects devoted to extension and improvement of PostgreSQL. One of the directions mentioned above is to adapt PostgreSQL for parallel query processing. In this paper, the authors describe the architecture and design of PargreSQL parallel DBMS for analytical data processing on distributed multiprocessors. The paper describes the architecture and the design of PargreSQL parallel DataBase Management System (DBMS) for distributed memory multiprocessors. PargreSQL is based upon PostgreSQL open-source DBMS and exploits partitioned parallelism.
