Per-task energy accounting in computing systems
We present for the first time the concept of per-task energy accounting (PTEA) and relate it to per-task energy metering (PTEM). We show the benefits of supporting both in future computing systems. Using the shared last-level cache (LLC) as an example: (1) We illustrate the complexities in providing...

| Resumo: | We present for the first time the concept of per-task energy accounting (PTEA) and relate it to per-task energy metering (PTEM). We show the benefits of supporting both in future computing systems. Using the shared last-level cache (LLC) as an example: (1) We illustrate the complexities in providing PTEM and PTEA; (2) we present an idealized PTEM model and an accurate and low-cost implementation of it; and (3) we introduce a hardware mechanism to provide accurate PTEA in the cache. |
