Dear Colleague:

We are pleased to announce the release of a new issue of Journal of
Computing Science and Engineering (JCSE), published by the Korean Institute
of Information Scientists and Engineers (KIISE). KIISE is the largest
organization for computer scientists in Korea with over 4,000 active
members. 

Journal of Computing Science and Engineering (JCSE) is a peer-reviewed
quarterly journal that publishes high-quality papers on all aspects of
computing science and engineering. JCSE aims to foster communication between
academia and industry within the rapidly evolving field of Computing Science
and Engineering. The journal is intended to promote problem-oriented
research that fuses academic and industrial expertise. The journal focuses
on emerging computer and information technologies including, but not limited
to, embedded computing, ubiquitous computing, convergence computing, green
computing, smart and intelligent computing, and human computing. JCSE
publishes original research contributions, surveys, and experimental studies
with scientific advances.

Please take a look at our new issue posted at http://jcse.kiise.org

[Paper One]

- Title: Reducing GPU Energy Consumption by Packing Narrow-Width Operands

- Authors: Xin Wang and Wei Zhang

- Keyword: Graphics processing units (GPUs); Register file; Leakage energy;
Narrow-width operands

- Abstract

In this paper, we study the use of an Operand-Width-Aware Register (OWAR)
packing mechanism for graphics processing unit (GPU) energy saving. In order
to efficiently use the GPU register file (RF), OWAR employs a power gating
method to shut down unused register sub-arrays in order to reduce dynamic
and leakage energy consumption of RF. As the number of register accesses was
reduced due to the packing of the narrow width operands, the dynamic energy
dissipation was further decreased. Finally, with the help of RF usage
optimized by register packing, OWAR allowed GPUs to support more
thread-level parallelism (TLP) through assigning additional thread blocks on
streaming multiprocessors (SMs) for general-purpose GPU (GPGPU) applications
that suffered from the deficiency of register resources. The extra TLP opens
opportunities for hiding more memory latencies and thus reducing the overall
execution time, which can lower the overall energy consumption. We evaluated
OWAR using a set of representative GPU benchmarks. The experimental results
showed that compared to the baseline without optimization, OWAR can reduce
the GPGPU's total energy up to 29.6% and 9.5% on average. In addition, OWAR
achieved performance improvement up to 1.97X and 1.18X on average.

[Paper Two]

- Title: Structure-Behavior Coalescence Method for Formal Specification of
UML 2.0 Sequence Diagrams

- Authors: Steve Haga, William Shanchung Chao, and Wei-Ming Ma

- Keyword: Structure-behavior coalescence; Sequence diagram; Message
sending-and-receiving event transition

- Abstract

This paper presents the structure-behavior coalescence (SBC) method for the
formal specification of UML sequence diagrams. The SBC method, also named
SBC sequence diagrams (SBC-SqD), includes syntax and semantics. The syntax
allows the hierarchy of a sequence diagram to be represented as a parse
tree. The semantic meaning of that sequence diagram is then represented by
its message sending-and-receiving event transition graph (MSRETG). In order
to create this MSRETG, the semantic meaning of sequence diagram (SD) modules
is presented, including the meaning of these modules when they are used in a
hierarchy that defines another module. Such hierarchical decomposition is
formally provided for all sequence diagram modules, including all types of
loops. In UML, all SD modules are also called combined fragments (CF). The
obtained MSRETG has advantages over previous formal specifications, because
it is a fully-complete specification and is compact and readable.

[Paper Three]

- Title: Analysis and Evaluation of Channel-Hopping-Based MAC in Industrial
IoT Environment

- Authors: Donghwa Yoo, Sanghwa Chung, and Jeongbae Park

- Keyword: Wireless technologies; Embedded software; Embedded control and
communication

- Abstract

Owing to the development of the Internet-of-Things (IoT) paradigm, channel
hopping is the most widely used method for solving multipath fading problem
caused by various structures in industrial environments or by external
interference of communication devices using the same frequency band. To meet
these demands, IPv6 over the time slotted channel hopping (TSCH) mode of
IEEE 802.15.4e (6TiSCH) has emerged as the standard for low power lossy
networks in industrial IoT environments. TSCH supports slot-based channel
hopping with the IEEE 802.15.4e standard and ensures reliable connection
from external interference through strong time synchronization. Wireless
Smart Utility Network (Wi-SUN), which constructs a Field Area Network (FAN),
proposes non-slotted channel hopping and specifies only minimum constraints.
However, there is limited existing research on these networks. Therefore, in
this study, we analyze and evaluate the performance of channel-hopping-based
medium access control (MAC) in an industrial environment. Simulation results
in various environments show that non-competitive MAC provides reliable and
efficient transmission.
