Neural Networks, graph analytics, and other big-data applications have become vastly important for many domains. This has led to a search for proper computing systems that can efficiently utilize the tremendous amount of data parallelism that is associated with these applications. Generally, we depend on data centers and high-performance computing (HPC) clusters to run various big-data applications. However, the design of data centers is dominated by power, thermal, and physical constraints. On the contrary, emerging heterogeneous manycore processing platforms that consist of CPU and GPU cores along with memory controllers (MCs) and accelerators have small footprints. Moreover, they offer power and area-efficient tradeoffs for running big-data applications. Consequently, heterogeneous manycore computing platforms represent a powerful alternative to the data center-oriented type of computing. However, typical Network-On-Chip (NoC) infrastructures employed on conventional manycore platforms are highly sub-optimal to handle specific needs CPUs, GPUs, and accelerators. To address this challenge, we need to come up with a holistic approach to design an optimal network-on-chip (NoC) as the interconnection backbone for the heterogeneous manycore platforms that can handle CPU, GPU, and application-specific accelerator communication requirements efficiently. We will discuss design of a hybrid NoC architecture suitable for heterogeneous manycore platforms. We will also highlight effectiveness of machine learning-inspired multi-objective optimization (MOO) algorithms to quickly find a NoC that satisfies both CPU and GPU communication requirements. Widely used MOO techniques (e.g., NSGA-II or simulated annealing based AMOSA) can require significant amounts of time due to their exploratory nature. Therefore, more efficient, and scalable ML-based optimization techniques are required. We are going to discuss various features of a generalized application-agnostic heterogeneous NoC design that achieves similar levels of performance (latency, throughput, energy, and temperature) as application-specific designs.
