Abstract
Assigning nodes to jobs based on reliability factors includes calculating the maximum value of a processor utilization efficiency and assigning an optimal number of spare nodes to the job based on the value of the processor utilization efficiency.
Claims15
A method for assigning nodes to jobs based on reliability factors, comprising:
- calculating a maximum value of a processor utilization efficiency;
- and
- assigning an optimal number of spare nodes to a job based on said maximum value of said processor utilization efficiency.
A system for assigning nodes to jobs based on reliability factors, the system comprising:
- a calculation engine to:
- calculate the average time for a checkpoint-restart after a primary node failure;
- calculate an optimal checkpoint interval and an AFPR for said multiple nodes;
- calculate a probability that a spare node is available when desired;
- calculate a maximum value of the processor utilization efficiency;
- and
- an assigning engine to assign an optimal number of spare nodes to said job based on said value of the processor utilization efficiency.
4 more elements
A computer program product for assigning nodes to jobs based on reliability factors, comprising:
- a non-transitory computer readable storage medium, said non-transitory computer readable storage medium comprising computer readable program code embodied therewith, said computer readable program code comprising program instructions that, when executed, causes a processor to:
- receive a request to schedule a job that uses multiple nodes;
- calculate a maximum value of a processor utilization efficiency;
- and
- assign an optimal number of spare nodes to a job based on said maximum value of said processor utilization efficiency.
