Abstract

Dynamic pool reallocation performed by the following steps: (i) defining a plurality of resource pools including a first pool and a second pool, where each resource pool has a plurality of assigned resources; (ii) receiving a plurality of jobs to be executed; (iii) for each job of the plurality of jobs, assigning a respective resource pool, of the plurality of resource pools, to be used in completing the job; (iv) determining a preliminary schedule for executing the jobs on their respective resource pools; (v) determining whether the preliminary schedule will cause any jobs to miss service level agreement (SLA) deadlines corresponding to the job; (vi) executing the plurality of jobs on their respectively assigned resource pools; and (vii) re-assigning first resource from the second pool to the first pool during at least some of the time of the execution of the first job by the first resource pool.

First claim

What is claimed is:

1 . A method comprising:
defining a plurality of resource pools including a first pool and a second pool, where each resource pool has a plurality of assigned resources; receiving a plurality of jobs to be executed; for each job of the plurality of jobs, assigning a respective resource pool, of the plurality of resource pools, to be used in completing the job; determining a preliminary schedule for executing the jobs on their respective resource pools; determining whether the preliminary schedule will cause any jobs to miss service level agreement (SLA) deadlines corresponding to the job; executing the plurality of jobs on their respectively assigned resource pools; and on condition that a first job, of the plurality of jobs and assigned to the first resource pool, will miss an associated SLA deadline under the preliminary schedule, re-assigning first resource from the second pool to the first pool during at least some of the time of the execution of the first job by the first resource pool.

2 . The method of claim 1 further comprising:
after the execution of the first job by the first resource pool, re-assigning the first resource back to the second resource pool.

3 . The method of claim 2 wherein:
the re-assignment of the first resource to the first pool occurs immediately before the execution of the first job; and
the re-assignment of the first resource to the second pool occurs immediately after the execution of the first job.

4 . The method of claim 1 wherein the determination of the preliminary schedule is based, at least in part, upon processing resources available in the plurality of resource pools, input/output (I/O) resources available in the plurality of resource pools, memory resources available in the plurality of resource pools, and network usage.

5 . The method of claim 1 further comprising:
for each job of the plurality of jobs, classifying the job as critical or non-critical; and
wherein the determination of the preliminary schedule is based, at least in part, upon respective classifications, as critical or non-critical of the plurality of jobs.

6 . The method of claim 1 wherein the determination of the preliminary schedule is performed by an analyzer component.

7 . The method of claim 1 wherein the re-assignment of the first resource to the first pool is performed by a configurator component.
