[Paper One]

- Title: Design and Implementation of a Framework for Context-Aware
Preference Queries

- Authors: Patrick Roocks, Markus Endres, Alfons Huhn, Werner Kießling,
Stefan Mandl

- Keyword: Databases; Preferences; Context awareness; Personalization

- Abstract

In this paper we present a framework for a novel kind of context-aware
preference query composition whereby queries for the Preference SQL system
are created. We choose a commercial e-business platform for outdoor
activities as a use case and develop a context model for this domain within
our framework. The suggested model considers explicit user input, domain-
specific knowledge, contextual knowledge and location-based sensor data in
a comprehensive approach. Aside from the theoretical background of
preferences, the optimization of preference queries and our novel generator
based model we give special attention to the aspects of the implementation
and the practical experiences. We provide a sketch of the implementation
and summarize our user studies which have been done in a joint project with
an industrial partner.

[Paper Two]

- Title: Design Methodologies for Reliable Clock Networks

- Authors: Deokjin Joo, Minseok Kang, Taewhan Kim

- Keyword: Clock design; System reliability; System-on-chip; Embedded
systems

- Abstract

This paper overviews clock design problems related to the circuit
reliability in deep submicron design technology. The topics include the
clock polarity assignment problem for reducing peak power/ground noise,
clock mesh network design problem for tolerating clock delay variation,
electromagnetic interference aware clock optimization problem, adjustable
delay buffer allocation and assignment problem to support multiple voltage
mode designs, and the state encoding problem for reducing peak current in
sequential elements. The last topic belongs to finite state machine (FSM)
design and is not directly related to the clock design, but it can be
viewed that reducing noise at the sequential elements driven by clock
signal is contained in the spectrum of reliable circuit design from the
clock source down to sequential elements.

[Paper Three]

- Title: Static Timing Analysis of Shared Caches for Multicore Processors

- Authors: Wei Zhang, Jun Yan

- Keyword: Performance; Reliability; WCET analysis; Multicore processors;
Unified caches

- Abstract

The state-of-the-art techniques in multicore timing analysis are limited to
analyze multicores with shared instruction caches only. This paper proposes
a uniform framework to analyze the worst-case performance for both shared
instruction caches and data caches in a multicore platform. Our approach is
based on a new concept called address flow graph, which can be used to
model both instruction and data accesses for timing analysis. Our
experiments, as a proof-of-concept study, indicate that the proposed
approach can accurately compute the worst-case performance for real-time
threads running on a dual-core processor with a shared L2 cache (either to
store instructions or data).

[Paper Four]

- Title: High Performance Computing: Infrastructure, Application, and
Operation

- Authors: Byung-Hoon Park, Youngjae Kim, Byoung-Do Kim, Taeyoung Hong,
Sungjun Kim, John K. Lee

- Keyword: High performance computing; Supercomputer; Parallel file system;
Green technology

- Abstract

The last decades have witnessed an increasingly indispensible role of high
performance computing (HPC) in science, business and financial sectors, as
well as military and national security areas. To introduce key aspects of
HPC to a broader community, an HPC session was organized for the first time
ever for the United States and Korea Conference (UKC) during 2012. This
paper summarizes four invited talks that each covers scientific HPC
applications, large-scale parallel file systems, administration/maintenance
of supercomputers, and green technology towards building power efficient
supercomputers of the next generation.

[Paper Five]

- Title: A Comparative Performance Study for Compute Node Sharing

- Authors: Jeho Park, Shui F. Lam

- Keyword: Resource sharing; Resource allocation; Time-sharing cluster; Job
scheduling; High performance computing; Percentage slowdown

- Abstract

We introduce a methodology for the study of the application-level
performance of time-sharing parallel jobs on a set of compute nodes in high
performance clusters and report our findings. We assume that parallel jobs
arriving at a cluster need to share a set of nodes with the jobs of other
users, in that they must compete for processor time in a time-sharing
manner and other limited resources such as memory and I/O in a space-
sharing manner. Under the assumption, we developed a methodology to
simulate job arrivals to a set of compute nodes, and gather and process
performance data to calculate the percentage slowdown of parallel jobs. Our
goal through this study is to identify a better combination of jobs that
minimize performance degradations due to resource sharing and contention.
Through our experiments, we found a couple of interesting behaviors for
overlapped parallel jobs, which may be used to suggest alternative job
allocation schemes aiming to reduce slowdowns that will inevitably result
due to resource sharing on a high performance computing cluster. We suggest
three job allocation strategies based on our empirical results and propose
further studies of the results using a supercomputing facility at the San
Diego Supercomputing Center.

[Paper Six]

- Title: Computational Methods for On-Node Performance Optimization and
Inter-Node Scalability of HPC Applications

- Authors: Byoung-Do Kim, Carlos Rosales-Fernandez, Sungho Kim

- Keyword: Application optimization; Scalability; Performance engineering;
Computational modeling

- Abstract

In the age of multi-core and specialized accelerators in high performance
computing (HPC) systems, it is critical to understand application
characteristics and apply suitable optimizations in order to fully utilize
advanced computing system. Often time, the process involves multiple stages
of application performance diagnosis and a trial-and-error type of approach
for optimization. In this study, a general guideline of performance
optimization has been demonstrated with two class-representing
applications. The main focuses are on node-level optimization and inter-
node scalability improvement. While the number of optimization case studies
is somewhat limited in this paper, the result provides insights into the
systematic approach in HPC applications performance engineering.

[Paper Seven]

- Title: Algorithm for Improving the Computing Power of Next Generation
Wireless Receivers

- Authors: Syed S. Rizvi

- Keyword: Computing power; DS-CDMA systems; Power efficiency; Wireless
communications; Wireless receive

- Abstract

Next generation wireless receivers demand low computational complexity
algorithms with high computing power in order to perform fast signal
detections and error estimations. Several signal detection and estimation
algorithms have been proposed for next generation wireless receivers which
are primarily designed to provide reasonable performance in terms of signal
to noise ratio (SNR) and bit error rate (BER). However, none of them have
been chosen for direct implementation as they offer high computational
complexity with relatively lower computing power. This paper presents a low-
complexity power-efficient algorithm that improves the computing power and
provides relatively faster signal detection for next generation wireless
multiuser receivers. Measurement results of the proposed algorithm are
provided and the overall system performance is indicated by BER and the
computational complexity. Finally, in order to verify the low-complexity of
the proposed algorithm we also present a formal mathematical proof.
