Techniques for increasing the isolation of workloads within a multiprocessor instance

One or more non-transitory computer readable media including instructions that, when executed by one or more processors, cause the one or more processors to perform the steps of:

• determining a plurality of performance cost components associated with executing a plurality of workloads on a plurality of processors, wherein each performance cost component indicates a separate portion of an overall performance impact, wherein the overall performance impact is caused by cache interference that occurs when executing the plurality of workloads, and wherein each performance cost component is attributable to a corresponding factor associated with the cache interference;
• determining the overall performance impact caused by the cache interference based on the plurality of performance cost components;
• determining a first plurality of processor workload assignments based on a second plurality of processor workload assignments and the performance impact;
• and
• causing at least one processor included in the plurality of processors to execute at least a portion of a first workload that is included in the plurality of workloads based on at least one processor workload assignment included in the first plurality of processor workload assignments.

A system, comprising:

• one or more memories storing instructions;
• and
• a plurality of processors that are coupled to the one or more memories and, when executing the instructions, are configured to:
• determine a plurality of performance cost components associated with executing a plurality of workloads on a plurality of processors, wherein each performance cost component indicates a separate portion of an overall performance impact, wherein the overall performance impact is caused by cache interference that occurs when executing the plurality of workloads, and wherein each performance cost component is attributable to a corresponding factor associated with the cache interference;
• determine the overall performance impact that is caused by the cache interference based on the plurality of performance cost components;
• perform one or more optimization operations on a plurality of processor workload assignments based on the performance impact to generate a second plurality of processor workload assignments;
• and
• cause at least one processor included in the plurality of processors to execute at least a portion of a first workload that is included in the plurality of workloads based on at least one processor workload assignment included in the second plurality of processor workload assignments.
