Resource-based scheduler
Resource-based scheduling of computer jobs is disclosed. A computer job is scheduled based on utilization of a resource and a utilization criterion that the computer job has pertaining to the resource, in accordance with an embodiment of the present invention.
1. A method, comprising:
identifying a plurality of resource worklists corresponding respectively to each of a plurality of resources of different types, each resource worklist comprising computer jobs waiting to utilize a respective resource;
identifying one or more attributes of each of the plurality of resources;
selecting an order for scheduling use of the plurality of resources based on the attributes of each of the plurality of resources; and
based on the order: selecting a particular resource, for scheduling, from the plurality of resources,
after selecting the particular resource for scheduling: selecting, for execution using the particular resource, a particular computer job from a plurality of computer jobs on a resource worklist corresponding to the resource; and
scheduling the use, of the plurality of resources in the selected order, by one or more corresponding computer jobs, wherein scheduling the use comprises scheduling the use of the particular resource by the particular computer job;
wherein the method is executed by at least one device including a hardware processor.
2. The method of claim 1 , wherein selecting the order for scheduling the use of the plurality of resources based on the attributes of each of the plurality of resources comprises: placing a first resource before a second resource in the order responsive to determining that a first priority associated with the first resource is higher than a second priority associated with the second resource.
3. The method of claim 1 , wherein selecting the order for scheduling the use of the plurality of resources based on the attributes of each of the plurality of resources comprises: placing a first resource before a second resource in the order responsive to determining that a first speed associated with the first resource is slower than a second speed associated with the second resource.
4. The method of claim 1 , wherein the plurality of resources comprises a central processing unit (CPU) and a disk I/O, and the disk I/O is placed before the CPU in the selected order.
5. The method of claim 1 , wherein the plurality of resources comprises a disk I/O and a network I/O, and the disk I/O is placed before the network I/O in the selected order.
6. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising:
identifying a plurality of resource worklists corresponding respectively to each of a plurality of resources of different types, each resource worklist comprising computer jobs waiting to utilize a respective resource;
identifying one or more attributes of each of the plurality of resources;
selecting an order for scheduling use of the plurality of resources based on the attributes of each of the plurality of resources; and
based on the order: selecting a particular resource, for scheduling, from the plurality of resources,
after selecting the particular resource for scheduling: selecting, for execution using the particular resource, a particular computer job from a plurality of computer jobs on a resource worklist corresponding to the resource; and
scheduling the use, of the plurality of resources in the selected order, by one or more corresponding computer jobs, wherein scheduling the use comprises scheduling the use of the particular resource by the particular computer job.
7. The medium of claim 6 , wherein selecting the order for scheduling the use of the plurality of resources based on the attributes of each of the plurality of resources comprises: placing a first resource before a second resource in the order responsive to determining that a first priority associated with the first resource is higher than a second priority associated with the second resource.
8. The medium of claim 6 , wherein selecting the order for scheduling the use of the plurality of resources based on the attributes of each of the plurality of resources comprises: placing a first resource before a second resource in the order responsive to determining that a first speed associated with the first resource is slower than a second speed associated with the second resource.
9. The medium of claim 6 , wherein the plurality of resources comprises a central processing unit (CPU) and a disk I/O, and the disk I/O is placed before the CPU in the selected order.
10. The medium of claim 6 , wherein the plurality of resources comprises a disk I/O and a network I/O, and the disk I/O is placed before the network I/O in the selected order.
11. A system, comprising:
at least one device including a hardware processor;
the system being configured to perform operations comprising:
identifying a plurality of resource worklists corresponding respectively to each of a plurality of resources of different types, each resource worklist comprising computer jobs waiting to utilize a respective resource;
identifying one or more attributes of each of the plurality of resources;
selecting an order for scheduling use of the plurality of resources based on the attributes of each of the plurality of resources; and
based on the order: selecting a particular resource, for scheduling, from the plurality of resources,
after selecting the particular resource for scheduling: selecting, for execution using the particular resource, a particular computer job from a plurality of computer jobs on a resource worklist corresponding to the resource; and
scheduling the use, of the plurality of resources in the selected order, by one or more corresponding computer jobs, wherein scheduling the use comprises scheduling the use of the particular resource by the particular computer job.
12. The system of claim 11 , wherein selecting the order for scheduling the use of the plurality of resources based on the attributes of each of the plurality of resources comprises: placing a first resource before a second resource in the order responsive to determining that a first priority associated with the first resource is higher than a second priority associated with the second resource.
13. The system of claim 11 , wherein selecting the order for scheduling the use of the plurality of resources based on the attributes of each of the plurality of resources comprises: placing a first resource before a second resource in the order responsive to determining that a first speed associated with the first resource is slower than a second speed associated with the second resource.
14. The system of claim 11 , wherein the plurality of resources comprises a central processing unit (CPU) and a disk I/O, and the disk I/O is placed before the CPU in the selected order.
15. The system of claim 11 , wherein the plurality of resources comprises a disk I/O and a network I/O, and the disk I/O is placed before the network I/O in the selected order.
