摘要: We propose and evaluate a multi-thread memory scheduler that targets high performance CMPs. The proposed is based on concepts originally developed for network fair queuing scheduling algorithms. provides Quality of Service (QoS) while improving system performance. On four processor CMP running workloads containing mix applications with range bandwidth demands, the QoS to all threads in workloads, improves by an average 14% (41% best case), reduces variance threads' target utilization from .2 .0058.
