SYnergy: Fine-Grained Energy-Efficient Heterogeneous Computing for Scalable Energy Saving
SessionTopics in Cloud Computing
DescriptionEnergy-efficient computing uses power management techniques such as frequency scaling to save energy. Implementing energy-efficient techniques on large-scale computing systems is challenging. While most modern architectures, including GPUs, are capable of frequency scaling, these features are often not available on large systems.
We propose SYnergy, a novel energy-efficient approach that spans languages, compilers, runtimes, and job schedulers to achieve unprecedented fine-grained energy savings on large-scale heterogeneous clusters. SYnergy defines an extension to the SYCL programming model that allows programmers to define a specific energy goal for each kernel. Through compiler integration and a machine learning model, each kernel is statically optimized for the specific target. The methodology is inherently portable and has been evaluated on both NVIDIA and AMD GPUs. Experimental results show unprecedented improvements in energy and energy-related metrics on real-world applications, as well as scalable energy savings on a 64-GPU cluster.
