Thanks to the high speed Internet, basic video streaming has become an ordinary service nowadays. However, what is offered currently is far from the higher level services that enable stream viewers to \emph{interact} with the video streams. Interactive video streaming enables processing of the video streams upon viewers’ requests for a particular video. For instance, a viewer may request to watch a video stream with a particular resolution. Another example, is a viewer who requests to view a summary (highlights) of a video stream.

Cloud services have provided an ideal platform for video streaming providers to satisfy the computational demands needed for interactive video streaming. However, the problem in utilizing cloud services for interactive video streaming is:
"how to provide a robust interactive video streaming service through guaranteeing QoS desires of the viewers, while spending the minimum cost for the cloud services?" Accordingly, the objective of this tutorial is to present challenges, structures, and methods required to enable interactive video streaming that guarantee QoS in a cost-efficient manner. In particular, we present a framework for interactive video streaming called Interactive Video Streaming Engine (IVSE) that deals with the challenges of cloud-based interactive video streaming services and provides methods to address these challenges.

For the sake of cost-efficiency, the Resource Provisioning component supplies heterogeneous types of Virtual Machines (VM) where each VM has a different affinity with various arriving video processing tasks. As a result, the system creates and manages a dynamic heterogeneous VM cluster where the configuration of the VMs varies to conform to the arriving workload.

In summary, this tutorial describes innovations in interactive video streaming particularly in the following areas:
Robust, cost-efficient, and self-configurable VM provisioning policy: We will explain novel methods to provision a dynamic VM cluster that conforms its heterogeneity according to the arriving requests.
Heterogeneity- and QoS-aware scheduling method: It efficiently schedules streaming tasks on available heterogeneous VMs with the goal of minimizing both missing tasks’ deadlines and their startup delays.
Execution time prediction for video streaming tasks: We will elaborate on the influential factors of the video streaming tasks execution times. In addition, we will explain the way to model affinity exists between heterogeneous VMs and tasks while considering their cost difference.

A priority-aware admission control method: That prioritizes submission of streaming tasks to minimize the startup delay. The method can also consider the viewer subscription priority, and network speed at the viewers’ end.

Cost-efficient caching methods: We will elaborate on the trade-off between computation versus storage for video streams. We also provide a formal way to measure the hotness of video streams and provide methods that perform caching based on the hotness measure.

Intended audience:
Our tutorial provides guidelines for researchers and practitioners in Utility and Cloud Computing area who are interested into applications of cloud computing systems. Particularly, the tutorial will be of interest of those who research in heterogeneous computing, performance modeling, task scheduling, resource provisioning, and caching policies.

The findings, approaches, and outcomes can be beneficial to researchers who work on other High Performance Computing applications. We present our empirically-validated tools and evaluation benchmarks to real-world practice for use by practitioners and researchers. The tutorial provides a technology-transfer and will break down the barriers between the interactive video streaming and heterogeneous high performance computing based on cloud.

Machine Learning (ML) is becoming critical for many industrial and scientific endeavors, and has a growing presence in High Performance Computing (HPC) environments. Neural network training requires long execution times for large data sets, and libraries like TensorFlow implement GPU acceleration to reduce the total runtime for each calculation.

This tutorial demonstrates how to 1) use Chameleon Cloud to perform comparative studies of ML training performance across different hardware configurations; and 2) run and monitor power utilization of TensorFlow on NVIDIA GPUs.

Intended audience:
Students or academia researchers interested in measuring performance and power utilization on GPUs, and individuals interested in learning to use bare metal cloud systems to evaluate hardware for system design.

Understanding Performance Interference Benchmarking and Application Profiling Techniques for Cloud-hosted Latency-sensitive Application

Tuesday afternoon, December 5, Salon B

Dr. Aniruddha Gokhale - http://www.dre.vanderbilt.edu/~gokhale/ (will not be able to attend)

Cloud infrastructure providers must have an up to date understanding of their cloud resources’ usage so that they can effectively manage their cloud platforms while supporting multi-tenancy. At the same time, timely and scalable access to various resource usage statistics is critical to service providers, who host their services in the cloud, so they can ensure that their services provide the required quality of service to their customers through elastic and on demand auto-scaling while minimizing service-hosting costs.

To that end, these providers must understand how their services will perform under a variety of multi-tenancy scenarios and workload patterns. Conducting such benchmarking experiments and obtaining the desired resource statistics to pinpoint the sources of problems, such as level of performance interference which stem from multi-tenancy, is a hard problem due to a variety of reasons including heterogeneity in hardware and operating systems, and availability of hardware-specific, low-level statistics collection tools all of which make it extremely complex for providers to use existing capabilities and extend them as hardware changes and the statistics collection needs change. These challenges are further amplified as cloud platforms increasingly span fog and edge resources. Thus, a framework that is extensible and provides a higher level of abstraction to make it easy to use is needed.

Although, modern frameworks such as collectd are designed to address these challenges, these tools provide only the building blocks, thereby making the users responsible to integrate and extend the capabilities. To overcome these challenges this tutorial presents a framework called INDICES, which builds on collectd, while providing an integrated and extensible framework for users to rapidly conduct a variety of performance benchmarking experiments and collect a range of resource usage and application performance statistics. This tutorial focuses on the design of INDICES and provides attendees with basic hands-on experimentation, and describes how INDICES can be deployed in the cloud.

Intended audience:
The tutorial targets an audience with interest in resource management and those who want to develop expertise in server performance monitoring and benchmarking.

Platform-as-a-Service (PaaS) clouds offer services to automate the deployment and management of applications, relieving application owners of the complexity of managing the underlying infrastructure resources. However, application owners have an increasingly larger diversity and volume of workloads, which they want to execute at minimum cost while maintaining desired performance guarantees.

In this tutorial we give an overview how existing PaaS systems cope with this challenge. In particular, we present a taxonomy of commonly-encountered design decisions regarding how PaaS systems manage underlying resources. We then use this taxonomy to discuss an extensive set of PaaS systems targeting different application domains.

Intended Audience:
The tutorial targets a broad audience, encompassing PhD students, researchers in cloud computing and engineers developing PaaS services or cloud applications.

HPC Meets Cloud: Building Efficient Clouds for HPC, Big Data, and Deep Learning Middleware and Applications

Friday morning and afternoon, December 8, Salon A
- Dhabaleswar K. (DK) Panda (http://www.cse.ohio-state.edu/~panda)
- Xiaoyi Lu (http://www.cse.ohio-state.edu/~luxi)

Significant growth has been witnessed during the last few years in HPC clusters with multi-/many-core processors, accelerators, and high-performance interconnects (such as InfiniBand, Omni-Path, iWARP, and RoCE). To alleviate the cost burden, sharing HPC cluster resources to end users through virtualization for both scientific computing and Big Data processing is becoming more and more attractive.

In this tutorial, we first provide an overview of popular virtualization system software on HPC cloud environments, such as hypervisors (e.g., KVM), containers (e.g., Docker, Singularity), OpenStack, Slurm, etc. Then we provide an overview of high-performance interconnects and communication mechanisms on HPC clouds, such as InfiniBand, RDMA, SR-IOV, IVShmem, etc. We further discuss the opportunities and technical challenges of designing high-performance MPI runtime over these environments.

Next, we introduce our proposed novel approaches to enhance MPI library design over SR-IOV enabled InfiniBand clusters with both virtual machines and containers. We also discuss how to integrate these designs into popular cloud management systems like OpenStack and HPC cluster resource managers like Slurm. Not only for HPC middleware and applications, we will demonstrate how high-performance solutions can be designed to run Big Data and Deep Learning workloads (like Hadoop, Spark, TensorFlow, CNTK, Caffe) in HPC cloud environments.

Intended audience:
This tutorial is targeted for various categories of people working in the areas of HPC, Big Data processing, and Deep Learning on modern HPC clouds with high-performance interconnects. Specific audience this tutorial is aimed at include:

• Scientists, engineers, researchers, and students engaged in designing next-generation HPC, Big Data, and Deep Learning systems and applications over HPC clouds with high-performance interconnects;

• Designers and developers of Cloud Computing, HPC, Big Data, Deep Learning, OpenStack, Slurm, MPI, Hadoop, Spark, gRPC/TensorFlow, etc. middleware;

• Newcomers to the field of Cloud Computing, HPC, Big Data processing, and Deep Learning on modern high-performance computing clusters who are interested in familiarizing themselves with OpenStack, Slurm, MPI, Hadoop, Spark, gRPC/TensorFlow, RDMA, high-performance networking, etc.;

• Managers and administrators responsible for setting-up next generation HPC Clouds to efficiently run HPC, Big Data, and Deep Learning workloads in their organizations/laboratories.

CANCELED - Survey Analytics from Questionnaires and Textual Social Media Analytics Using Geometrical Data Analysis

Friday afternoon, December 8, Classroom 201
(This portion of the event has been canceled due to speaker illness.)

- Mohsen Farid, University Derby, United Kingdom
- Fionn Murtagh, University of Huddersfield, United Kingdom

Geometrical reasoning focuses on creating point clouds for rows and point clouds for columns for contingency tables (two-way cross tabulation). Projecting clouds onto planes, leads to useful new representations of data. Correspondence analysis, which is a geometrical analysis reasoning, aims to show the linkages between pairs of qualitative variables within qualitative (i.e. questionnaires) and textual data. It shows the difference between the given data and what it would be like if independence was assume. Therefore, the CA analysis shows the deviation from independence.

Pierre Bourdieu (1930 – 2002), a celebrated French social scientist, in his book, “Distinction”, translated into English in 1984, used Correspondence Analysis creatively. Correspondence analysis is a geometrical data analysis approach and it is the basis for this short course.

In Bourdieu’s view, Correspondence Analysis is a relational procedure that exposes and expresses social reality as opposed to the traditional statistical tools in which he had a vivid view: In La Distinction, 1979, p 103, “The particular relations between a dependent variable e.g. political opinion and so-called independent variables such as gender, age and religion, tend to disseminate the complete system of relations that make up the true principle of the force and form specific effects recorded in such and such particular correlation”, (in B. Le Roux and H. Ruanet – Sage Publications)

The focus in this course will be on:
  • interpretation of results, graphical displays and other outputs,
  • practical implementation using the R statistical and visualization environment, and
  • providing intuition, and full understanding, relating to the geometry and statistical processing.

We use data collected in various questionnaires, starting from work by Bourdieu on cultural taste.

Other questionnaire analysis case studies will be related to transport, cooking and lifestyle, student experience, consumer behavior, and music appreciation.

Next the questionnaire outcomes express both closed, fixed format questions, and, conjointly analyzed, free text responses.

Finally studied will be data sourced from social media micro-blogging, i.e. Twitter.

Tools: The course uses the R programming and visualization language
Topics: In accompanying online course materials, there will be a practical introduction to the R language and environment. This is for participants who have not used R before.

  1. Questionnaire analysis case study: taking the Bourdieu taste data, detailed discussion of output, detailing the R code used.
  2. Geometric intuition: the methodology used for graphical display, hierarchical clustering, and putting it all together.
  3. Carrying out geometric data analysis, including clustering, using R. Including publication/presentation outputs, storing data for later work, and maintaining the R scripts that are used.
  4. Further case studies of questionnaire analysis.
  5. Questionnaire analysis, using conjoint, or integrally related, analysis of closed questions, and open or free text questions.
  6. Coverage of social media data sources, will be especially centered on Twitter.

All sessions will be associated with practical exercises, using case studies.

The final part of the course will be a short debate and discussion on potential and scope for analytics, and statistical treatment of data, and text mining.

Intended Audience:
Practitioners and researchers related to any domains that are encompassed in the case studies, and practical exercises. Students who are undertaking, or who are planning to undertake, any and all such work.

Domains of general relevance include:

  • Health and medical surveys,
  • Marketing,
  • Security and forensics,
  • Information and data sourcing through web-based questionnaires,
  • Lifestyle and wellbeing analytics,
  • Legal studies,
  • Political studies,
  • Language and literature,
  • Digital humanities.

The presentation language of the short course is English. Case studies will also be in English as well, however issues related to other languages such as Arabic may be addressed.

Supplementary Material:
Course notes and other support material (code, resources, papers) will be available online.
