Problems solved by technology

When the scale of the system computing nodes is huge, in this way, due to the existence of one-to-many single-point bottlenecks, the bandwidth of the overall job control point restricts the efficiency of information transmission, resulting in long job startup time and poor efficiency.

Abstract

The invention discloses a method for transferring operation global task information in parallel computation. The method comprises the following steps of: determining required resources of at least one intermediate layer according to an operation scale in the parallel computation; and transferring the operation global task information to the resources of each intermediate layer in a one-to-many mode by an operation master controller, and transferring the operation global task information to computing nodes through the resources of each intermediate layer, wherein the quantity of the intermediate layers is smaller than that of the computing nodes. By adoption of the method, the transferring time of the operation global task information is shortened, the starting efficiency of large-scale operation is improved, and network pressure is effectively relieved.

Description

Technical field [0001] The present invention relates to the field of network communication, in particular to a method for transferring job global task information in parallel computing. Background technique [0002] In parallel computing, it is necessary to transfer and deploy job global task information to all computing nodes running subject tasks. As the time-consuming part of the start-up process, the speed of global job task information transmission and deployment will directly affect the start-up time and efficiency of the entire job. [0003] In the current mainstream job management system, the job task information is transmitted to all computing nodes directly in the job master control through a single-level one-to-many approach. When the scale of the system computing node is huge, in this way, due to the one-to-many single-point bottleneck, the bandwidth of the job total control point restricts the efficiency of information transmission, resulting in long job startup time ...
