Abstract

The invention discloses an MPI communication method and system of GTC software. The method comprises the steps that spatial position parameters of high-energy particles are obtained; by means of the spatial position parameters, the target MPI process aiming at the high-energy particles is determined; particle information of the high-energy particles is sent to the target MPI process. That is to say, after the target MPI process is determined, the particle information is directly sent to the target MPI process, the phenomenon of aimless particle information transmission does not exist, it is guaranteed that time of MPI communication has nothing to do with the number of the MPI processes, therefore, the technical problem that in the prior art, the time of the MPI communication is significantly increased along with increase of the node scale is effectively solved, and the operation performance of the GTC software is significantly improved.

Description

technical field [0001] The invention relates to the technical field of parallel program design and optimization in the field of high-performance computing, in particular to an MPI communication method and system of GTC software. Background technique [0002] At present, GTC (Gyrokinetic Toroidal Code) is a large-scale parallel software for turbulence simulation of nonlinear gyrodynamics. It is a key program for simulating high-energy particle turbulence in fusion energy exploration). [0003] In practical applications, GTC can reproduce the evolution process of plasma over time by simulating the transport properties of plasma under the action of a magnetic field. ), which plays a very important role in finally solving the human energy problem. [0004] In the existing MPI (Multipoint Interface, multipoint interface) communication method of the GTC software, the MPI communication process is very complicated. Rank 0, Rank 1, ..., Rank N are the numbers of N MPI processes. ...
