Quiet Noisy Neighbor with Intel® RDT

When virtual machines are widely deployed in cloud environment, companies are looking for solutions to maximize cloud investment. In cloud environment, there are multiple applications running on the same infrastructure, high priority applications may not obtain sufficient and appropriate hardware resources to run best due to shared resources underneath. Cloud Service Providers (CSPs) often try t...o mitigate this problem by restricting the amount of resources that a customer application can use to avoid over-subscription of resources. To better manage noisy neighbors, it is crucial for CSPs to have sufficient monitoring and control mechanisms in place to detect and address noisy-neighbor interference at a more granular level. Intel® Resource Director Technology (Intel® RDT) offers such mechanisms to monitor and control interferences that occur on the processor. The objective of the experiment was to study the impact of different neighbors on an application’s performance and to show how Intel® RDT can help to detect and mitigate a noisy-neighbor situation.
