The invention provides a method and a system for task scheduling. The method comprises the following steps: estimating both the calculated load and memory load of a received task and obtaining the calculated load estimated value and the memory load estimated value; if the proportion of the calculated load estimated value in the sum of both the calculated load estimated value and the memory estimated value is larger than a preset first threshold, scheduling the task to a node in which the present computing power is larger than the preset upper limit value of the computing power and the presentmemory power is smaller than the preset lower limit value of the memory power; and if the proportion of the memory load estimated value in the sum of the calculated load estimated value and the memory load estimated value is larger than a preset second threshold, scheduling the task to a node in which the present memory power is larger than the preset upper limit value of the memory power and thepresent computing power is smaller than the preset lower limit value of the computing power.
Description
Technical field [0001] The present invention relates to the field of communications, in particular to a task scheduling method and system. Background technique [0002] In the cloud computing operating system, because the data volume of cloud computing tasks is very large, the calculation time is also very long, so if based on the traditional single task type scheduling method, the nodes in the system will not be able to maximize their own performance. Resources. [0003] In the process of implementing the present invention, the inventor found that the prior art has at least the following problems: the proportion of computing load or storage load in the overall task may vary greatly, resulting in heavy storage load of some nodes close to zero. , Other nodes are in continuous data access, and no calculations are allocated, which leads to partial waste of calculation or storage resources. Summary of the invention [0004] The task scheduling method and system provided by the present...
