Title of Keynote Speech: 

Neoteric Frontiers in Cloud, Edge, and Quantum Computing


Computing is being transformed to a model consisting of services that are delivered in a manner similar to utilities such as water, electricity, gas, and telephony. In such a model, users access services based on their requirements without regard to where the services are hosted or how they are delivered. Cloud computing paradigm has turned this vision of "computing utilities" into a reality. It offers infrastructure, platform, and software as services, which are made available to consumers as subscription-oriented services. Cloud application platforms need to offer (1) APIs and tools for rapid creation of elastic applications and (2) a runtime system for deployment of applications on geographically distributed Data Centre infrastructures (with Quantum computing nodes) in a seamless manner.

The Internet of Things (IoT) paradigm enables seamless integration of cyber-and-physical worlds and opening opportunities for creating new class of applications for domains such as smart cities, smart robotics, and smart healthcare. The emerging Fog/Edge computing paradigms support latency sensitive/real-time IoT applications with a seamless integration of network-wide resources all the way from edge to the Cloud.

This keynote presentation will cover (a) 21st century vision of computing and identifies various IT paradigms promising to deliver the vision of computing utilities; (b) innovative architecture 

for creating elastic Clouds integrating edge resources and managed Clouds, (c) Aneka 5G, a Cloud Application Platform, for rapid development of Cloud/Big Data applications and their deployment on private/public Clouds with resource provisioning driven by SLAs, (d) a novel FogBus software framework with Blockchain-based data-integrity management for facilitating end-to-end IoT-Fog/Edge-Cloud integration for execution of sensitive IoT applications, (e) experimental results on deploying Cloud and Big Data/ IoT applications in engineering, and health care (e.g., COVID-19), deep learning/Artificial intelligence (AI), satellite image processing, and natural language processing (mining COVID-19 research literature for new insights) on elastic Clouds, (f) QFaaS: A Serverless Function-as-a-Service Framework for Quantum Computing, and (g) directions for delivering our 21st century vision along with pathways for future research in Cloud and Edge/Fog computing.

Title of Keynote Speech:

Dos and Don’ts in Blockchain Research and Development


The goal of this talk is to clarify common misconceptions regarding the blockchain technology, and pointing out some worrisome practices in the field of blockchain technology. We first provide a brief introduction of the blockchain technology, highlighting its design principle, nuts and bolts, and the most fundamental innovation of the technology. Next, we elaborate on a key concept regarding data immutability. In particular, it is a mistake to equate blockchain to data immutability. Data immutability can only be achieved in large-scale public blockchains where the cost becomes an insurmountable barrier for any attempt to change the data recorded in the blockchain. The third topic we discuss is the differences between public, private, and consortium blockchains. We caution the use of private and consortium blockchains. The last topic we argue is regarding blockchain consensus. Because the proof of work (PoW) consensus algorithm has obvious drawbacks on energy consumption, many alternative algorithms have been proposed. We single out two most egregious wrong practices: (1) selecting a small set of validators for reaching consensus, and (2) adopting traditional distributed consensus.

Title of Keynote Speech: 

Blockchain Technology and its Application


Blockchain is a chained data structure consisting of blocks linked in chronological order. Each block needs to maintain an identical, continuously growing, and immutable ledger backup locally; blockchain is a technology that enables the secure sharing of information. Data, obviously, is stored in a database. Transactions are recorded in an account book called a ledger. In this report, we will explain blockchain technology and preliminarily explore its potential application areas.

Speech Title:  

Software project scheduling with multitasking


In software development projects, employees tend to switch between various tasks within a time period. In addition, the task duration usually depends on the number of the allocated employees and their skill levels. We investigate the software project scheduling problem with multitasking and variable durations (SPSPM). We present a non-linear optimization model that is then linearized into an equivalent mixed-integer linear programming model. To efficiently solve the NP-hard SPSPM, we design a two-stage priority rule-based heuristic algorithm and an improved genetic algorithm (GA). Extensive computational experiments are conducted on a benchmark dataset consisting of 540 project instances. The parameter settings of the GA are determined based on the Taguchi method for the Design of Experiment. The computational results obtained by comparing our algorithms with the exact solver CPLEX reveal that our GA is effective and competitive.
