Abstract

The invention discloses a communication method suitable for monitoring MPI (Message Passing Interface) parallel software. The method comprises an MPI communication process, an MPI calculation process and host monitoring software, and the MPI communication process comprises an OpenMP command thread and a state thread. The method comprises the following steps: 1, the MPI communication process receives a command of the host monitoring software, and forwards the command to the MPI calculation process in a non-blocking way; 2, the MPI calculation process receives the command transmitted by the MPI communication process, executes the command to control a calculation task, and transmits state information to the MPI communication process regularly or in an event-driving way; 3, the MPI communication process receives the state information of the MPI calculation process, and transmits the state information to the host monitoring software. By adopting the communication method, parallel software consisting of a plurality of MPI processes can be monitored via the host monitoring software, and the aim of hardly influencing the parallel software calculation performance is fulfilled.

Description

technical field [0001] The invention relates to a communication method suitable for monitoring MPI (message passing interface) parallel software, suitable for engineering application of MPI parallel software, and belongs to the field of computer parallel computing. Background technique [0002] At present, the high-performance cluster based on the MPI specification is a widely used parallel computing platform. MPI parallel software obtains efficient computing performance by running multiple MPI processes simultaneously on multiple computers interconnected by high-speed networks. [0003] At present, it is a common solution to develop MPI parallel software to realize tasks with large amount of data and large amount of computation. However, the commonly used development platform is based on a remote cluster system, most of which are installed with a Linux operating system. After the task is submitted, it is often passively waiting for completion. The programmer pays attentio...
