Heterogeneity in Computing Workshop

Call for Papers

In conjunction with IPDPS 2021, May 17, 2021, Portland, Oregon USA

Sponsored by the IEEE Computer Society
through the Technical Committee on Parallel Processing (TCPP)

Most modern computing systems are heterogeneous, either for organic reasons because components grew independently, as it is the case in desktop grids, or by design to leverage the strength of specific hardware, as it is the case in accelerated systems. In any case, all computing systems have some form of hardware or software heterogeneity that must been managed, leveraged, understood, and exploited. The Heterogeneity in Computing Workshop (HCW) is a venue to discuss and innovate in all theoretical and practical aspects of heterogeneous computing: design, programmability, efficient utilization, algorithms, modeling, applications, etc. The 2021 HCW is the 30th annual gathering of this workshop.

TOPICS
Topics of interest include but are not limited to the following areas:

!!! SPECIAL TOPIC !!! Heterogeneous computing for Machine Learning (ML): Design, exploration, and analysis of architectures and software frameworks, enabling significant performance improvement of Machine Learning algorithms/applications on heterogeneous computing systems. Well known architectures are the Nvidia DLA (deep learning accelerator) and DGX systems, SambaNova, and Cerebras. Example frameworks include Nvidia TensorRT, Tensorflow, Caffe2, and PyTorch.  Submissions in the following areas are very welcome: Designing and programming of Machine Learning accelerators (e.g., GPUs, FPGAs, or Coarse Grain Architectures), exploration and benchmarking of Machine Learning frameworks on heterogeneous computing systems.

Heterogeneous multicore systems and architectures: Design, exploration, and experimental analysis of heterogeneous computing systems such as GPGPUs, heterogeneous systems-on-chip (SoC), accelerator systems (e.g., Intel Xeon Phi, AI chips such as Google’s TPUs), FPGAs, big.LITTLE, and application-specific architectures.

Heterogeneous parallel and distributed systems: Design and analysis of computing grids, cloud systems, hybrid clusters, datacenters, geo-distributed computing systems, and supercomputers.

Deep-memory hierarchies: Design and analysis of memory hierarchies with SRAM, DRAM, Flash/SSD, and HDD technologies; NUMA architectures; cache coherence strategies; novel memory systems such as phase-change RAM, magnetic (e.g., STT) RAM, 3D Xpoint/crossbars, and memristors.

On-chip, off-chip and heterogeneous network architectures: Network-on-chip (NoC) architectures and protocols for heterogeneous multicore applications; energy, latency, reliability, and security optimizations for NoCs; off-chip (chip-to-chip) network architectures and optimizations; heterogeneous networks (combination of NoC and off-chip) design, evaluation, and optimizations; large scale parallel and distributed heterogeneous network design, evaluation, and optimizations.

Programming models and tools: Programming paradigms and tools for heterogeneous systems; middleware and runtime systems; performance-abstraction tradeoff; interoperability of heterogeneous software environments; workflows; dataflows.

Resource management and algorithms for heterogeneous systems: Parallel algorithms for solving problems on heterogeneous systems (e.g., multicores, hybrid clusters, grids or clouds); strategies for scheduling and allocation on heterogeneous 2D and 3D multicore architectures; static and dynamic scheduling and resource management for large-scale and parallel heterogeneous systems.

Modeling, characterization, and optimizations: Performance models and their use in the design of parallel and distributed algorithms for heterogeneous platforms, characterizations and optimizations for improving the time to solve a problem (e.g., throughput, latency, runtime), modeling and optimizing electric consumption (e.g., power, energy); modeling for failure management (e.g., fault tolerance, recovery, reliability); modeling for security in heterogeneous platforms.

Applications on heterogeneous systems: Case studies; confluence of Big Data systems and heterogeneous systems; data-intensive computing; deep learning; scientific computing.
