Systems and methods for controlling process priority for efficient resource allocation

Abstract

Methods and systems for controlling process priority for one or more work units having one or more processes. The method includes monitoring a combination of a throughput value and a response time value for each work unit, detecting a change in load level for each work unit based on a correlation between the throughput value and the response time value to adjust a priority level associated with the work unit, and reallocating one or more resources to the work unit when the priority level exceeds a predetermined threshold value.

 monitoring a combination of a throughput value and a response time value for each work unit;   detecting a change in load level for each work unit based on a correlation between the throughput value and the response time value to adjust a priority level associated with the work unit; and   reallocating one or more resources to the work unit when the priority level exceeds a predetermined threshold value.   
     
     
         10 . The non-transitory computer readable storage medium of  claim 9 , wherein the work unit is a container having at least one application, the at least one application including at least one process.

         12 . The non-transitory computer readable storage medium of  claim 9 , wherein reallocating the one or more resources includes reallocating memory to the work unit. 
     
     
         13 . The non-transitory computer readable storage medium of  claim 12 , further comprising increasing the priority level associated with the work unit when the throughput value and the response time value are increased such that swappiness of the memory is decreased for the work unit. 
     
     
         14 . The non-transitory computer readable storage medium of  claim 12 , further comprising decreasing the priority level associated with the work unit when the throughput value and the response time value are decreased such that swappiness of the memory is increased for the work unit. 
     
     
         15 . The non-transitory computer readable storage medium of  claim 9 , further comprising maintaining the priority level associated with the work unit when one of the throughput value and the response time value is increased. 
     
     
         16 . The non-transitory computer readable storage medium of  claim 9 , further comprising maintaining the priority level associated with the work unit when one of the throughput value and the response time value is decreased. 
     
     
         17 . A system, comprising:
 a memory; and   a hardware processor configured to:
 monitor a combination of a throughput value and a response time value for each work unit from one or more work units, the one or more work units having one or more processes; 
 detect a change in load level for each work unit based on a correlation between the throughput value and the response time value to adjust a priority level associated with the work unit; and 
 reallocate one or more resources to the work unit when the priority level exceeds a predetermined threshold value.
