摘要
大数据和高性能计算都是计算机技术发展的产物。高性能计算主要采用模拟方法，被称作科学发现的第三范
式；大数据主要从数据中总结规律，即使在对研究对象缺乏深入理解的情况下也可以发现一定的相关性，被
称作科学发现的第四范式。从研究范式、主要应用类型以及计算机软硬件系统的角度对大数据与高性能计
算的关系展开阐述。

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
