最初由NASA的Ames研究中心开发，主要为了提供一个能满足异构计算网络需要的软件包，用于灵活的批处理，特别是满足高性能计算的需要，如集群系统、超级计算机和大规模并行系统。PBS的主要特点有：代码开放，免费获取；支持批处理、交互式作业和串行、多种并行作业，如MPI、 PVM、HPF、MPL；PBS是功能最为齐全, 历史最悠久, 支持最广泛的本地集群调度器之一. PBS的目前包括openPBS, PBS Pro和Torque三个主要分支. 其中OpenPBS是最早的PBS系统, 目前已经没有太多后续开发, PBS pro是PBS的商业版本, 功能最为丰富. Torque是Clustering公司接过了OpenPBS, 并给与后续支持的一个开源版本.(Originally developed by NASA's Ames Research Center, mainly to provide a software package that can meet the needs of heterogeneous computing network, for flexible batch processing, especially to meet the needs of high-performance computing, such as cluster system, supercomputer and massively parallel system. The main features of PBS are: open source, free access; support batch, interactive operation, a variety of parallel and serial operation, such as MPI, PVM, HPF, MPL; PBS is the most complete, the oldest and one of the most extensive local cluster. The scheduler supports PBS including openPBS, three main PBS Pro and Torque. The branch of OpenPBS is the first PBS system, at present there is not much development, PBS Pro is a commercial version of PBS, is the most feature rich. Torque Clustering company took over OpenPBS, and give an open source version of the follow-up support.)
