Abstract

Disclosed are systems and methods of performing a power cap processing in a compute environment. The method includes determining of one of committed resources and dedicated resources in a compute environment exceed a threshold value for a job. If a determination is yes that the threshold value is exceeded, then the method includes preempting processing of the job in the compute environment by performing one of migrating the job to a new compute resources and performing a power reduction action associated with the job, such as slowing down a processor associated with a job or cancelling the job. When such a power state reduction action is taken, reservations associated with other jobs may also be adjusted.

Claims

1. A method comprising:

determining if one of committed resources and dedicated resources in a compute environment comprising multiple separate compute servers that are connected via a network exceeds a threshold value for a first workload to be processed under a first reservation, to yield a determination, wherein each separate compute server comprises a central processing unit; and

if the determination is yes;

(1) preempting processing of the first workload in the compute environment by performing a power state reduction action associated with the first workload; and

(2) based on the power state reduction action, adjusting a second reservation associated with a second workload that differs from the first workload, wherein adjusting the second reservation comprises changing the second reservation from a first server to second server in the compute environment.

2. The method of claim 1, wherein the power state reduction action is one of slowing down a processor and cancelling the first workload.

3. The method of claim 1, wherein performing the power state reduction action keeps power consumption for the first workload under a predetermined threshold value.

4. A system comprising:

a processor; and

a computer-readable storage medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising;

determining if one of committed resources and dedicated resources in a compute environment comprising multiple separate compute servers that are connected via a network exceeds a threshold value for a first workload to be processed under a first reservation, to yield a determination, wherein each separate compute server comprises a central processing unit; and

if the determination is yes;

(1) preempting processing of the first workload in the compute environment by performing a power state reduction action associated with the first workload; and

(2) based on the power state reduction action, adjusting a second reservation associated with a second workload that differs from the first workload, wherein adjusting the second reservation comprises changes to the second reservation from a first server to a second server in the compute environment.

5. The system of claim 4, wherein the power state reduction action is one of slowing down a processor and cancelling the first workload.

6. The system of claim 4, wherein performing the power rate reduction action keeps power consumption for the first workload under a predetermined threshold value.

7. A non-transitory computer-readable storage media storing instructions which, when executed by a processor, cause the processor to perform operations comprising:

determining if one of committed resources and dedicated resources in a compute environment comprising multiple separate compute servers that are connected via a network exceeds a threshold value for a first workload to be processed under a first reservation, to yield a determination, wherein each separate compute server comprises a central processing unit; and

if the determination is yes;

(1) preempting processing of the first workload in the compute environment by performing a power state reduction action associated with the first workload; and

(2) based on the power state reduction action, adjusting a second reservation associated with a second workload that differs from the first workload, wherein adjusting the reservation comprises changes to the second reservation from a first server to a second server in the compute environment.

8. The non-transitory computer-readable storage media of claim 7, wherein the power state reduction action is one of slowing down a processor and cancelling the first workload.

9. The non-transitory computer-readable storage media of claim 7, wherein performing the power rate reduction action keeps power consumption for the first workload under a predetermined threshold value.
