Abstract:

Both big data and high performance computing (HPC) are based on the computer technologies. The main methodology of HPC is simulation, which is called the third paradigm of scientific discovery. Big data explore data for correlations even without much knowledge on the object of study, which is called the fourth paradigm of scientific discovery. Big data and HPC with several aspects were compared, such as the research paradigm, main application domain and underlying hardware/software systems.

Key words: big data, high performance computing, parallel and distributed computing, correlation
