Modeling program resource demand using inherent program characteristics

The workloads in modern Chip-multiprocessors (CMP) are becoming increasingly diversified, creating different resource demands on hardware substrate. It is necessary to allocate hardware resources based on the needs of the workloads in order to improve system efficiency and/or ensure Quality-of-Service (QoS) at certain performance levels. Therefore, it is extremely important to identify the resource demand of the workload in terms of the performance and power efficiency. Existing models are inappropriate for estimating resource demands as they require either partial simulations or time-consuming training. This paper presents an integrated framework that is able to identify the single-resource or multi-resource demands on an array of hardware resources ranging from the issue width of the processor to the memory bandwidth. With an analytical model based on program inherent characteristics, this framework does not require any detailed simulation or training yet is still able to capture...
