Special Issue Information

Dear Colleagues,

While computing technologies have remained relatively stable for nearly two decades, new architectural features, such as specialized hardware, heterogeneous cores, deep memory hierarchies, and near-memory processing, have emerged as possible solutions to address the concerns of energy efficiency, manufacturability, and cost. However, we expect this ‘golden age’ of architectural change to lead to extreme heterogeneity, and it will have a major impact on software systems and applications. In this upcoming exascale and extreme heterogeneity era, it will be critical to explore new software approaches that will enable us to effectively exploit this diverse hardware to advance science, and next-generation systems with heterogeneous elements will need to accommodate complex workflows. This is mainly due to the many forms of heterogeneous accelerators (no longer just GPU accelerators) in this heterogeneous era, and the need for mapping different parts of an application onto elements most appropriate for that application component.

The goal of this Special Issue is to provide a forum to discuss new and emerging solutions to address these important challenges in the upcoming extreme heterogeneity era. Papers are being sought on many aspects of heterogeneous computing, including (but not limited to):

Heterogeneous programming environments and runtime systems

  • Programming models and systems
  • Parallel resource management on heterogeneous systems
  • Automated parallelization and compiler techniques (Autotuning)

Heterogeneous solutions for HPC and scientific applications

  • Parallel and distributed algorithms
  • Parallel libraries and frameworks
  • Parallel processing on heterogeneous systems

Heterogeneous (including non-von Neuman) architectures

  • Power/energy management
  • Heterogeneous architectures for emerging application domains
  • Architecture designs including non-von Neuman architectures, memory and interconnection Reliability/benchmarking/measurements
  • Debugging, performance tools and techniques
  • Fault tolerance and resilience
  • Application/hardware benchmarks

Tuning tensor program generation involves navigating a vast search space to find optimal program transformations and measurements for a program on the target hardware. The complexity of this process is further amplified by the exponential combinations of transformations, especially in heterogeneous environments. This research addresses these challenges by introducing a novel approach that learns the joint neural network and hardware features space, facilitating knowledge transfer to new, unseen target hardware. A comprehensive analysis is conducted on the existing state-of-the-art dataset, TenSet, including a thorough examination of test split strategies and the proposal of methodologies for dataset pruning. Leveraging an attention-inspired technique, we tailor the tuning of tensor programs to embed both neural network and hardware-specific features. Notably, our approach substantially reduces the dataset size by up to 53% compared to the baseline without compromising Pairwise Comparison Accuracy (PCA). Furthermore, our proposed methodology demonstrates competitive or improved mean inference times with only 25–40% of the baseline tuning time across various networks and target hardware. The attention-based tuner can effectively utilize schedules learned from previous hardware program measurements to optimize tensor program tuning on previously unseen hardware, achieving a top-5 accuracy exceeding 90%. This research introduces a significant advancement in autotuning tensor program generation, addressing the complexities associated with heterogeneous environments and showcasing promising results regarding efficiency and accuracy.
