This paper describes design ideas,architecture and implementation techniques of a kind of multi-tenant high availability parallel task scheduling framework named MTHPT.It consists of three parts:task definition and configuration,asynchronous parallel task scheduling mode,alarm messages and monitoring.Task scheduling engine and task execution components use separate deployments,asynchronous parallel scheduling and fast callback mode,quick releasing thread resource scheduling engine,which can solve such issues as:part of the task long implementation cycle,timed task that can not be performed on time and other issues that affect the business performance of the system.Task scheduling configuration provides a multi-tenant application model.Experimental analysis and assessment show that MTHPT improves the efficiency and stability of task parallel scheduling application system.
