Problems solved by technology

Therefore, in recent years, a lot of research has focused on how to optimize system execution performance under the condition of satisfying the maximum power consumption constraints of the system, which is called peak power management; however, most of the existing power management methods are oriented towards isomorphic parallelism. The system does not consider the difference in speed or power consumption between different computing units, making it difficult to efficiently apply to heterogeneous parallel systems based on acceleration components

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] In the present invention, the processor set composed of the main processor and the acceleration component executing the same application program is called "heterogeneous processing engine" (Heterogeneous Processing Engine, HPE for short). Let HPE consist of m processors, denoted as R={r 0 ,...,r m-1}, where the i-th processor r i The quantity is denoted as N i , its dynamic power consumption and speed at the highest frequency are denoted as P i and V i , speed refers to the amount of tasks completed by the processor per unit time. According to the power consumption formula of CMOS circuits, the relationship between the dynamic power consumption of the processor and the operating frequency can be approximately expressed as p=Cf α , where C is a constant related to the architecture, and the coefficient α is between 2 and 3....

Abstract

Disclosed is a maximum power consumption control method for a high-performance heterogeneous parallel computer. The method includes that a system-level power consumption controller distributes total power consumption to multiple heterogeneous processing engines HPE in concurrent execution according to contribution of different application programs to overall system efficiency and executive efficiency of each concurrent job under the condition of given system power consumption restraint; and an HPE power consumption controller adopts an application-aware power consumption strategy to distribute power pHPE to heterogeneous processors in the HPEs by means of coordinate parallel task dividing and processor frequency adjusting. The maximum power consumption control method for the high-performance heterogeneous parallel computer has the advantages of simple principle, simplicity and convenience in operation, capability of optimizing executing performance of a parallel system, shortening task executing time and improving operating efficiency of the system, and the like.

Description

technical field [0001] The invention mainly relates to the design field of high-performance computers, in particular to a power consumption control method suitable for high-performance heterogeneous parallel computers. Background technique [0002] The heterogeneous parallel system integrates general-purpose processors and high-performance (computing performance per unit power consumption) special-purpose processors. It has high peak performance and effectively improves the overall performance of the system. It has become one of the important trends in the development of high-performance computers. . Although heterogeneous parallel systems have higher peak performance, the absolute power consumption of the system is still high. Excessive power consumption brings great challenges to system packaging, power supply and heat dissipation. Therefore, power consumption is not only an important goal of system optimization, but also gradually becomes one of the important constraints...
