Theme:

The memory system is becoming heterogeneous and intelligent. Multiple memory components with different properties (e.g., latency, bandwidth and capacity) are put together, introducing memory heterogeneity; Some memory components could have computing capability and be equipped with machine learning models, introducing memory intelligence. Memory heterogeneity and intelligence are useful to increase memory capacity, reduce production cost, and avoid data movement. However, memory heterogeneity and intelligence introduce new challenges on memory allocation and reclamation, data migration, programming methods, and so on.

This session aims to discuss how to manage emerging heterogenous and intelligent memory systems. The purpose of this workshop is to bring together computer scientists and domain scientists from academia,and industry to share recent advances in heterogenous and intelligent memory systems.

Title: Designing Fast and Scalable Storage Systems for Heterogeneous Memory

Abstract: Nowadays, fast and scalable storage systems become much more important for Big Data analytics and management. The emerging heterogeneous memory technologies in the form of NVMe-SSDs and PMEMs offer persistence with unprecedented performance. These technologies have the potential to change the fundamental design principles of storage systems. In this talk, we rethink the assumptions and design paradigms of traditional storage systems and propose new storage schemes to take advantage of heterogeneous memory technologies. Specifically, we will first present DStore, a decoupled storage model which builds a fast and persistent object store on PMEM. We further present NVMe-CR, which aims to scale checkpoint I/O workloads on supercomputers using NVMe-over-Fabrics. Finally, we will discuss RDMP-KV, which proposes PMEM-aware RDMA-based communication protocols for persistent key-value stores.

Theme:

Robots, unmanned aerial vehicles, intelligent terminals in the home, smart phones, tablet computers, and other end side devices demand efficient image processing algorithms. Deep neural networks are widely used in computer vision tasks such as image classification and object detection, and they have made impressive improvements over the last few years. Owing to their huge commercial value, deep learning and convolutional neural networks have become research hotspots, and numerous excellent work have been conducted. At present, traditional deep neural networks are designed to extract more expressive depth features via a very deep neural network structure. This has presented a huge challenge to the deployment of convolution neural networks on various hardware platforms, especially mobile and edge devices, and has severely limited the development and application of deep neural networks on portable devices. The key to improving the efficiency and ability of mobile terminals to process image and video data, and to meeting the constraints of storage space and power consumption, lies in the lightweight design, model compression, and acceleration of deep neural networks, and this has been highlighted by academia and industry. This special session aims to promote the deployment and implementation of lightweight deep neural network models in edge devices.

Title: Information Network embedding for A New Generation of Geosocial Recommendations

Abstract: The rapid development of mobile Internet, location acquisition and 5G communication technologies has fostered a profusion of geo-social networks (e.g., Foursquare, Yelp and Google Place). They provide users an online platform to check-in at points of interests (e.g., cinemas, galleries and hotels) and share their life experiences in the physical world via mobile devices. The new dimension of location implies extensive knowledge about user behaviours and interests by bridging the gap between online social networks and the physical world. It is crucial to develop new geo-social recommendation services for both individual users and groups to explore the new places, attend new events and find their potential partners to attend these events together. This keynote will introduce three emerging geo-social recommendation paradigms and their new challenges:  spatial item recommendation for mobile users, spatial item recommendation for dynamic groups, and joint spatial item and partner recommendation.  This talk will also explore how to adopt and advance the network embedding techniques to address the new challenges in the three geo-social recommendation services.

Title: Towards a Unified Framework for Weakly-Supervised Learning

Abstract: As a classic learning problem, weakly supervised learning has so far induced a variety of specific learning paradigms. Regarding insufficient, indefinite, and inaccurate supervision, various methods such as semi-supervised learning, PU learning, multi-instance learning, and label noise learning have emerged. Although there are many kinds of weakly supervised learning methods, the previous studies on different methods are isolated from each other. Therefore, whether there is a unified weakly supervised learning framework to fundamentally model various weakly supervised situations is worthy of further exploration. By keeping this in mind, this talk mainly presents a general weakly supervised learning framework called "Centroid Estimation with Guaranteed Efficiency". The core of the framework is to design an unbiased and efficient empirical risk estimator for various weakly-supervised situations via loss decomposition and centroid estimation. The designed framework can cover a variety of typical weakly supervised learning methods such as semi-supervised learning, PU learning, multi-instance learning and label noise learning, and shows encouraging performance on different types of benchmark datasets.

Title: Efficient Object Detection in the Open World

Abstract: Object detection, which is a hot research topic in the artificial intelligence and computer vision field, has been widely applied to robot navigation, video surveillance, industrial inspection, etc. Traditional object detection models, containing millions of parameters, highly rely on the large-scale well-annotated datasets in the close experimental setting, which is inflexible to an unexpected situation. However, in the real, open world, such as X-ray security inspection, key information is inclined to be interfered due to the complex background or malicious camouflage, and training data of certain categories are hard to be collected. What is worse, the hardware deployment environment is also restricted. Therefore, object detection task in the open world faces the challenges of weak targeting signal, sparse training data and limited computing resources, which deviates from the closed experimental setting created by traditional large-scale datasets. This talk will focus on the efficient object detection problems in the open world and present a series of accurate, reliable and efficient object detection approaches, respectively from signal inhibition, semantic evolution and information retention. Besides, three high-quality annotated benchmarks based on real-world scenarios will be introduced in this keynote, to promote the research of object detection in the open world. Also, this talk will further discuss the future development of efficient object detection, to face the challenges of openness, complexity and rivalry in the open world.

Title: Computational Storage: Another Fantasy or A Real Big Thing?

Abstract: The rapidly growing interest in heterogeneous computing has recently moved computational storage into the limelight. It has a beautifully simple rationale: Moving computational tasks closer to where data reside could improve the overall system performance/efficiency. Intuitively, this simple rationale makes a perfect sense and cannot be possibly refuted. However, its large-scale commercial success has remained elusive so far, despite so many awesome research papers and 100s' millions of dollars spent on its R&D. This disappointing status quo warrants doubts and skepticisms: Will it turn out to be an over-hyped fantasy just like many others we have seen over the years? Are there any fatal flaws in this simple idea? Facing these questions, proponents of computational storage must be brutally honest to themselves and humbly search for the (inconvenient) truth, other than conveniently blaming the industry reluctance/laziness on embracing disruptive technologies. In this talk, I will discuss the pitfalls of prior and on-going R&D efforts, and present the correct (or at least the best) way to commence its commercialization journey. I will also show that there is still a large room for innovations in this area, despite many papers published over the past 20 years. Finally, although this talk solely focuses on computational storage, the lessons we learned could also help to prevent "in-memory computing" or "computational memory" (another hot topic today) from becoming yet another academic fantasy.

Title: Towards Energy-efficient System and Architecture for Artificial Intelligence

Abstract: Artificial Intelligence (AI) has empowered many key areas, such as security monitoring, autonomous driving, national defense equipment, etc. However, the computation volume of AI has shown an explosive growth trend. Taking security monitoring as an example, security cameras around the world generate about 2500PB of data every day and processing these data requires the memory capacity of 10^8 Nvidia T4 GPUs. The corresponding overall computing power consumption is as high as 7.5×10^6 KW for one year, which is equivalent to the annual power generation capacity of 0.66 Three Gorges hydropower stations. To promote the rapid implementation of artificial intelligence in various life scenarios, it is necessary to realize the efficient mapping of artificial intelligence algorithms to hardware systems, which poses a huge challenge to the design of intelligent-oriented systems and hardware architectures. On the one hand, there is a contradiction between the rapid increase in computing power requirements of intelligent algorithms and the slow improvement of general hardware energy efficiency. On the other hand, there is a contradiction between the unstructured sparse data structure and the structured hardware architecture. This report will introduce structured sparse pruning and dynamic low-bit quantization technologies, which will reduce computation and bandwidth requirements by 10-20 times without loss of accuracy. The designed FPGA-specific accelerators achieve up to 40 times and 16 times of energy efficiency compared with CPUs and GPUs. improvement. We propose the “pruning-quantizing-customization” neural network software and hardware co-design method, which is widely used in the industry. We also propose the FPGA-based coarse-grained instruction set architecture and neural network layer fusion compilation flow, reducing the hardware deployment cost of any neural network model to the order of hundreds of seconds, breaking the problem of a long development cycle of dedicated hardware for intelligent algorithms. Furthermore, for larger and more sparse Graph Neural Network scenarios (GNN), we target accelerating GNNs on GPUs from following perspectives, including accelerating operators, unifying interface, and optimizing computational graph. Our sparse kernel on GPU achieves up to 14.01x speedup compared with the state-of-the-art cuSPARSE design. For typical GNN model, our design achieves an acceleration of up to 3.67x compared with the traditional framework. We form a complete library for both sparse operators and GNN models. All these researches are included in an open-sourced project, namely dgSPARSE. We hope that researchers and developers in related domains could join this open ecology and contribute to the community.

Theme:

With the success of ML (Machine Learning), continued growth in data volume, and increasing availability of large-scale and highly complex computing systems, interactions between ML and systems have drawn much attention in the ML/AI and system research communities and IT industry. People are studying how to build systems to better support the recent advances in machine learning (Systems for ML) and how we can leverage machine learning to improve systems (ML for Systems). There have been workshops and conference sessions dedicated on either of the directions. 

On the one hand, new hardware and software systems, such as new generations of GPUs, hardware accelerators (e.g., TPU), open source frameworks (e.g., TensorFlow and Apache Spark), have enabled training increasingly complex models on ever larger datasets. On the other hand, ML has been employed in the system optimizations on aspects such as scheduling, data structure design, microarchitecture, compilers, memory management, database system, and resource allocation and service quality control in warehouse scale computing systems. 

It is clear that advances of ML and systems can positively impact each other. And the impacts are necessary and can be significant. This panel will invite prominent scholars and practitioners who are conducting research and product development on systems and ML technologies in the academia and IT industry to share their experience and offer their opinions on various issues about the interactions between ML and systems. The panel presentations and discussions are expected to engage audience on potential and limits, pros and cons, and success stories and learned lessons on leveraging ML and systems for each other’s optimizations and to provide suggestions on identification of opportunities for leveraging one to improve the other. 


  Panel Topics:

    Tentative topics to be discussed on the panel include:

   •  To what extent can bottlenecks on ML/AI performance and quality be ameliorated with more powerful and optimized hardware/software supports?

   •  What are the major gaps for today's hardware/software supports to meet the demand of running ML/AI applications?

     •  To what extent do the system designs need to be customized for accelerating ML/AI applications, including designs of computer architecture, networking, I/O and storage systems, OS, and fault tolerance and recovery?

     •  What system design problems can be more effectively addressed than empirical approaches?  

     •  What are the limits for ML/AI to help with system designs, and what are the risks and concerns in the effort?   

     •  While an ML/AI model functions largely as a black box, we may not be able to easily interpret and understand its decision and to obtain insights on interaction between systems and these workloads. How can we remedy this potential problem?
