Abstract
Programs running on different cores in a multicore server are often forced to share resources like off-chip memory, caches, I/O devices, etc. This resource sharing often leads to degraded performance, a slowdown, for the programs that share the resources. A job scheduler can improve performance by co-scheduling programs that use different resources on the same server. The most common approach to solve this co-scheduling problem has been to make job-schedulers resource aware, finding ways to characterize and quantify a program's resource usage. We have earlier suggested a simple, program and resource agnostic, scheme as a stepping stone to solving this problem: A...
