A practical method for estimating performance degradation on multicore processors, and its application to HPC workloads

When multiple threads or processes run on a multi-core CPU they compete for shared resources, such as caches and memory controllers, and can suffer performance degradation as high as 200%. We design and evaluate a new machine learning model that estimates this degradation online, on previously unsee...
