Abstract

The invention discloses a resource management method facing a GPU (Graphic Processing Unit) cluster, which comprises the following steps: a main management node establishes two charts (a resource information chart and a task information chart); the main management node receives a new task; the main management node judges whether the task is a CPU (Central Processing Unit) task or a GPU task; the main management node seeks free resource meeting the requirement of the task; if the task is a CPU task, a secondary management node conducts pretreatment on the data of the task, and dispensing pieces of the data to all nodes managed by the secondary management node for calculation, the main management node reclaims CPU resource related to all the nodes managed by the secondary management node according to the number of the task after calculation; if the task is a GPU task, the main management node reclaims the GPU resource related to all the nodes managed by the secondary management node according to the number of the task when GPU calculation is detected to be finished; meanwhile, the CPUs of all the nodes managed by the secondary management node are used for post-processing of a result, and the post-processing is finished. According to the invention, CPU resource and the GPU resource are treated differently; through the detection of the task, free GPU resource can be reclaimed fast.

Description

technical field [0001] The invention belongs to the field of computer high-performance computing, and more specifically relates to a GPU cluster-oriented resource management method and system. Background technique [0002] In recent years, with the continuous development of high-performance computing, GPU clusters have received more and more attention. The high performance of the GPU cluster is mainly attributed to its massively parallel multi-core structure, high throughput in multi-threaded floating-point arithmetic, and the use of large on-chip caches to significantly reduce the time for moving large amounts of data. GPU clusters not only provide a huge leap in speed performance, but also significantly reduce space, power, and cooling requirements. [0003] However, the current management of GPU clusters is mainly based on the management mode of CPU clusters, scheduling for CPU cores, and adopting a single centralized unified management mode: the entire cluster has only ...
