Improving IBM POWER8 Performance Through Symbiotic Job Scheduling

Symbiotic job scheduling, i.e., scheduling applications that co-run well together on a core, can have a considerable impact on the performance of processors with simultaneous multithreading (SMT) cores. SMTcores share most of their microarchitectural components among the co-running applications, whi...
