Guaranteeing Quality-of-Service (QoS) of latency-sensitive applications while improving server utilization through application co-location is important yet challenging in modern datacenters. The key challenge is that when applications are co-located on a server, performance interference due to resource contention can be detrimental to the application QoS. Although prior work has proposed techniques to identify "safe" co-locations where application QoS is satisfied by predicting the performance interference on multicores, no such prediction technique on accelerators such as GPUs.
