캐싱 알고리즘 동작 확인용 시뮬레이터 설계 및 구현

김우완,천희식 경남대학교 정보통신연구소 1999 연구논문집 Vol.1 No.-

멀티프로세서 시스템을 설계할 경우에는 공유 메모리 구조와 메시지 전달방법이라고 하는 두 가지의 패러다임을 바탕으로 하게 된다. 데이터 분할과 동적 부하 분산 문제를 단순화시킬 수 있으며 확장성을 용이하게 지원하는 장점을 가지고 있는 공유메모리 구조의 멀티프로세서 시스템에서 각 프로세서가 자신의 전용 캐시를 가지는 경우에는 메인 메모리와 이러한 전용 캐시내에 존재하는 데이터 사본간에 일관성 문제가 발생한다. 본 논문에서는 일관성 유지를 위해 제안되어 있는 여러 알고리즘 중 처리 노드와 고대역 저지연 인터커백션 네트워크로 구성되는 공유메모리 구조의 멀티프로세서 프로토타입인 DASH 프로토콜을 지원하기 위한 전용 버스 시스템을 완전 개방형인 IEEE Futurebus+ 스탠다드에 준하여 설계한 다음, 이 시스템이 DASH 프로토콜을 지원하며 캐시의 일관성을 유지하기 위해 필요한 각종 행동과 기존의 범용 버스 시스템이 수행하는 행동의 병렬 처리를 지원한다는 점을 전용 시뮬레이터를 통하여 증명한다. The design of a multi-processor system is based on one of the two approaches: a message-passing mechanism, and a shared-memory architecture[1]. The latter alternative gains an advantage over the former in that it can eliminate problems from the data partitioning and simplify dynamic load balancing so that a system adopting the architecture may be scaled with ease. On the other hand, if a certain shared-memory multiprocessor is allowed to have its own private cache memories, a problem how to keep the consistency between a block in main memory and the copy of the block in a cache shall arise[2][4]. This paper designs and implements a dedicated bus system supporting the DASH protocol, a prototype of a shared-memory multiprocessor consisting of processing nodes and high-bandwidth low-latency interconnection networks, in accordance with the completely open IEEE Futurebus+ Standards. The effectiveness and appropriateness of the bus system are verified through a simulation applied to the DASH protocol. In conclusion, the parallel processing of activities related to cache coherency and those related to existing common bus systems surpass the hardware redundancy induced by the dedicated bus system in performance.

TCP-friendly 혼잡 제어 기법에 관한 연구

김우완,천희식,장상동 慶南大學校 附設 工業技術硏究所 2003 硏究論文集 Vol.21 No.1

멀티캐스트 및 실시간 오디오/비디오 스트리밍 어플리케이션과 같은 새로운 커뮤니케이션 트렌드로 인하여 인터넷상에서 non-TCP 트래픽이 증가하는 추세에 있다. 이러한 어플리케이션은 TCP-friendly기준에 따르는 혼잡 제어를 거의 수행하고 있지도 않으며, 유효 대역폭을 웹 브라우저, FTP, 이메일 클라이언트 등과 같이 TCP를 기반으로 하는 어플리케이션과 공평하게 공유하지도 않는다. 그러므로 지금과 같은 추세로 나아간다면 인터넷은 TCP 트래픽의 Starvation과 Congestion Collapse를 발생시킬 가능성이 높다. 이를 위해 TCP 플로우와의 공존을 지원하는 TCP-friendly프로토콜이 개발되고 있다. 본 논문에서는 TCP friendliness를 위한 현재의 접근 방법을 살펴보고, 각각의 특징을 알아보기로 한다. 그리고 유니캐스트 및 멀티캐스트에 관한 여러 혼잡 제어 프로토콜을 상세히 살펴보기로 한다. Non-TCP traffic on the Internet is on an increasing trend due to new communication patterns such as multicast and real-time audio/video streaming applications. These applications inherently do not perform congestion control in accordance with TCP-friendly standard criteria, nor share valid bandwidth with TCP-based applications like Web Browsers, FTP. E-mail Clients, etc. This means that current drift on the Internet may produce a high possibility of starvation and congestion collapse of TCP traffic. To deal with the unwanted situation such as congestion collapse and starvation, many TCP-friendly protocols supporting non-TCP flows in keeping pace with TCP ones are proposed and still being developed. This paper comprehensively surveys current approaches to TCP-friendliness and their properties in detail in order to systematically aid researches in TCP congestion controls that are the subject of wide attention.

Iterative Symbol Decoding of Variable-Length Codes with Convolutional Codes

Wu, Hung-Tsai,Wu, Chun-Feng,Chang, Wen-Whei The Korea Institute of Information and Commucation 2016 Journal of communications and networks Vol.18 No.1

In this paper, we present a symbol-level iterative source-channel decoding (ISCD) algorithm for reliable transmission of variable-length codes (VLCs). Firstly, an improved source a posteriori probability (APP) decoding approach is proposed for packetized variable-length encoded Markov sources. Also proposed is a recursive implementation based on a three-dimensional joint trellis for symbol decoding of binary convolutional codes. APP channel decoding on this joint trellis is realized by modification of the Bahl-Cocke-Jelinek-Raviv algorithm and adaptation to the non-stationary VLC trellis. Simulation results indicate that the proposed ISCD scheme allows to exchange between its constituent decoders the symbol-level extrinsic information and achieves high robustness against channel noises.

Biomass accumulation and bioactive compound production from adventitious root cultures of Echinacea purpurea in bioreactors

Chun-Hua Wu,Eun-Joo Hahn,Kee-Yoeup Paek 한국작물학회 2007 한국작물학회 학술발표대회 논문집 Vol.2007 No.11

Echinacea purpurea is an important medicinal plant native of North America, which contains caffeic acid derivatives, alkamides, glycoproteins, and polysaccharides. For commercial roduction of bioactive compounds from Echinacea purpurea, adventitious roots were induced and proliferated in 5 and 20-liter bioreactors under various cultural conditions (Medium composition, inoculum density, air volume, light, temperature et al.). In a 5-liter bioreactor, more than 10-fold of biomass increment was achieved after 5 weeks of culture. Increases of root biomass and bioactive compounds were correlated with increased consumption of sucrose and macro/micro nutrients in the medium. Elicitations have been conducted with UV-C, NO, and SA to increase the accumulation of total polyphenolics, flavonoids and caffeic acid derivatives in the adventitious root cultures, which resulted in 1.2-1.6 times of increment. Based on the previous experimental results, 500-liter and 1000-liter scale bioreactors were applied for large scale cultures of Echinacea purpurea adventitious roots. Total root biomass of 3.62 kg and 5.05kg (dry weight) were achieved in a 500 L and a 1000 L bioreactor, respectively. The accumulation of 22.55 mg/g DW cichoric acid, 4.92 mg/g DW chlorogenic acid and 3.99 mg/g DW caftaric acids were also achieved from the adventitious root in a 1000-liter scale bioreactor.

Improved Production of Caffeic Acid Derivatives in Suspension Cultures of Echinacea purpurea by Medium Replenishment Strategy

Wu, Chun-Hua,Murthy, Hosakatte Niranjana,Hahn, Eun-Joo,Paek, Kee-Yoeup 대한약학회 2007 Archives of Pharmacal Research Vol.30 No.8

The aim of this study was to produce caffeic acid derivatives from adventitious root cultures of Echinacea purpurea, which are of high pharmaceutical value. The effects of both media optimization and replenishment strategies were adopted to achieve improved production of E. purpurea adventitious roots and caffeic acid derivatives. Of the different media strengths (0.25 MS, 0.5 MS, 0.75 MS and 1 MS) tested for the culturing of adventitious roots in 5 L bioreactors, 0.5 MS medium was found to be most suitable for the growth of adventitious roots. The optima accumulation of biomass (73.6 g $L^{-1}$ FW and 10.03 g $L^{-1}$ DW), phenolics (61.14 mg $g^{-1}$ DW) and flavonoids (38.30 mg $g^{-1}$ DW) were achieved in this medium. Furthermore, fed batch cultivations (media replenishment with 0.25 MS, 0.5 MS, 0.75 MS and 1 MS at the end of $2^{nd}$ and $3^{rd}$ weeks) to further enhance the production of adventitious root biomass and metabolites were also attempted. High adventitious root biomasses (83.1 g $L^{-1}$ FW and 15.30 g $L^{-1}$ DW) were achieved with feeding of the 0.5 MS medium at the end of $2^{nd}$ week. This led to slight decreases in the total production of phenolics and flavonoids; however, this feeding was responsible for increases in the accumulation of caftaric acid (5.76 mg $g^{-1}$ DW) and cichoric acid (26.12 mg $g^{-1}$ DW).

Wu, Bing-Li,Luo, Lie-Wei,Li, Chun-Quan,Xie, Jian-Jun,Du, Ze-Peng,Wu, Jian-Yi,Zhang, Pi-Xian,Xu, Li-Yan,Li, En-Min Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.12

Background: Fascin, an actin-bundling protein forming actin bundles including filopodia and stress fibers, is overexpressed in multiple human epithelial cancers including esophageal squamous cell carcinoma (ESCC). Previously we conducted a microarray experiment to analyze fascin knockdown by RNAi in ESCC. Method: In this study, the differentially expressed genes from mRNA expression profilomg of fascin knockdown were analyzed by multiple bioinformatics methods for a comprehensive understanding of the role of fascin. Results: Gene Ontology enrichment found terms associated with cytoskeleton organization, including cell adhesion, actin filament binding and actin cytoskeleton, which might be related to fascin function. Except GO categories, the differentially expressed genes were annotated by 45 functional categories from the Functional Annotation Chart of DAVID. Subpathway analysis showed thirty-nine pathways were disturbed by the differentially expressed genes, providing more detailed information than traditional pathway enrichment analysis. Two subpathways derivated from regulation of the actin cytoskeleton were shown. Promoter analysis results indicated distinguishing sequence patterns and transcription factors in response to the co-expression of downregulated or upregulated differentially expressed genes. MNB1A, c-ETS, GATA2 and Prrx2 potentially regulate the transcription of the downregulated gene set, while Arnt-Ahr, ZNF42, Ubx and TCF11-MafG might co-regulate the upregulated genes. Conclusions: This multiple bioinformatic analysis helps provide a comprehensive understanding of the roles of fascin after its knockdown in ESCC.
