  • 본 논문은 유한요소 구조해석의 선형해법으로 널리 사용되는 다중프론트 해법의 공유메모리 환경하의 병렬화 방법을 논의한다. 다중프론트 해법은 병렬성이 내재되어 있어서 여타 해법보다 상대적으로 병렬화가 용이한 방법이다. 다중프론트 해법의 공유메모리 컴퓨터에서 최적의 성능을 내도록 병렬 계산을 수행하기 위한 기법들이 제시되었다. 주로 독립적인 계산 작업 시에 필요한 주 메모리 용량을 줄이는 데 초점을 맞춘 방법들로서 프론트 행렬 연성화와 행렬 분리로 명명된 두 기법에 대해 자세히 설명한다. 개발된 방법으로 기존의 알고리즘과의 성능 비교를 수행하여 본지에 제안한 방법이 현대의 다중코어 컴퓨터에서 훨씬 더 효율적인 기법임을 입증하였다.

  • 내포병렬성을 가진 공유메모리 병렬프로그램의 효과적인 디버깅을 위해서, 프로그램의 비결정적 수행을 최초로 초래하는 경합을 효율적으로 탐지하는 것이 중요하다. 이러한 최초경합을 수행 중에 탐지하는 기존의 기법은 두 번의 프로그램 수행을 통해서 탐지하면서 각 공유변수마다 프로그램의 최대병렬성에 의존적인 크기의 접근역사를 유지하므로 비효율적인 수행시간과 기억공간을 요구한다. 본 논문에서는 두 번의 프로그램 수행을 통해서 수행 중에 각 공유변수에 대한 접근역사를 상수적 크기로 유지하므로, 각 접근사건의 수행 시에 상수적 복잡도의 사건비교 횟수와 기억 공간만을 요구하는 새로운 최초경합 탐지기법을 제안한다. 그러므로 본 기법은 내포병렬성을 가진 공유메모리 병렬프로그램의 디버깅을 위해서 보다 효율적이고 실용적인 경합탐지를 가능하게 한다

  • 공공도서관 소장자료의 효율적 관리와 새로운 서비스 공간 확보를 위하여 공동보존서고 건립의 필요성이 제기되고 있다. 공동보존서고는 단위 공공도서관의 보존공간 확충에 드는 비용을 절감하고, 도서관들이 오랜 기간 소장해온 저이용 자료 등을 이관함으로써 공간의 효율과 서비스의 집중도를 제고하기 위한 것으로, 결과적으로 도서관들은 보존 프로그램을 통합 운영하고 도서관별 필요 공간을 확보함으로써 시설, 정보자원, 인력의 공동 활용 및 효율성 제고를 기대할 수 있다. 이에 따라 지역의 대표도서관들을 중심으로 자료수장공간의 부족문제를 해결하기 위한 방안으로 공동보존서고 운영에 대한 논의가 이루어지고 있다. 이 연구에서는 그 일환으로 서울특별시를 중심으로 지역대표도서관이 주도하는 공동보존서고 건립 방안을 제안해 보았다. 이를 위해 서울시 공공도서관 소장장서의 향후 규모를 예측하고, 이를 근거로 적절한 공동보존서고의 규모와 시설안을 제안하였다.

  • Purpose: Recently, a sudden increase in one household in Korea has become an important social problem. Changes in lifestyles such as population change, marriage, childbirth, and divorce are becoming increasing factors for single-family households. As a result of these changes, the government has implemented policies for one accredited state. However, the policy for one domestic applicant is insufficient compared to other countries. As a measure to cope with the increase in the number of applicants, Shared House has emerged and research on Shared House is necessary. Method: First, we analyze the overall characteristics of domestic share house. And it does a spatial analysis of domestic share house. Especially, it analyzes the relationship between private space and public space. Finally, the plan characteristics are derived based on the analysis results. Result: The results are as follows. First, the type of share house is classified according to the combination of the arrangement of private space and the public space. Second, the larger the scale, the more vertical arrangement than horizontal arrangement. Finally, the character of the share house changes according to the characteristics of the resident.

  • This research is about shared living facilities for the solitary elderly in Gyeonggi province (so called "Carnation House"), which was opened after 2013. These facilities aim to help solving the social problems of the growing number of the solitary elderly. The research was conducted from April 2014 to October 2014 by using observation, measurement, photography, and interview methods. This research reviewed floor plan, area, accessibility, visual openness, and furniture and equipments. The results are as follows: First, considering the need for rest area and the protection of privacy, livingroom should at least be equipped with a variable wall or have a separate room. Secondly, for the kitchen plan, considering the fact that large number of people move simultaneously, kitchen entrance should be widened or LDK type is preferable. Thirdly, the bathroom entrance should be widened to at least 800mm and should have barrier free design. Fourthly, porch entrance should be planned to secure enough space and shoe cabinets for multiple users. Fifthly, to allow the users to enjoy outside view, the windows of living spaces should be placed no higher than 800mm from the floor level. Finally, for the location of the facility, people prefer the location be at the center of the village or near home. In addition, location with easy accessibility for the elderly is advisable. Therefore, establishing local guidelines for shared living facilities for the solitary elderly is advisable. When establishing local guidelines, local characters, culture and usage patterns should be considered.

  • In Distributed Shared Memory systems, false sharing occurs when two different data items, not shared but accessed by two different processors, are allocated to a single block and is an important factor in degrading system performance. The paper first analyzes shared memory allocation and reference patterns in parallel applications that allocate memory for shared data objects using a dynamic memory allocator. The shared objects are sequentially allocated and generally show different reference patterns. If the objects with the same size are requested successively as many times as the number of processors, each object is referenced by only a particular processor. If the objects with the same size are requested successively much more than the number of processors, two or more successive objects are referenced by only particular processors. On the basis of these analyses, we propose a memory allocation scheme which allocates each object requested by different processors to different pages and evaluate the existing memory allocation techniques for reducing false sharing faults. Our allocation scheme reduces a considerable amount of false sharing faults for some applications with a little additional memory space.

  • This paper provides a thorough study on shared segment protection (SSP) for mesh communication networks in the complete routing information scenario, where the integer linear program (ILP) in [1] is extended such that the following two constraints are well addressed: (a) The restoration time constraint for each connection request, and (b) the switching/merging capacity constraint at each node. A novel approach, called SSP algorithm, is developed to reduce the extremely high computation complexity in solving the ILP formulation. Basically, our approach is to derive a good approximation on the parameters in the ILP by referring to the result of solving the corresponding shared path protection (SPP) problem. Thus, the design space can be significantly reduced by eliminating some edges in the graphs. We will show in the simulation that with our approach, the optimality can be achieved in most of the cases. To verify the proposed formulation and investigate the performance impairment in terms of average cost and success rate by the additional two constraints, extensive simulation work has been conducted on three network topologies, in which SPP and shared link protection (SLP) are implemented for comparison. We will demonstrate that the proposed SSP algorithm can effectively and efficiently solve the survivable routing problem with constraints on restoration time and switching/merging capability of each node. The comparison among the three protection types further verifies that SSP can yield significant advantages over SPP and SLP without taking much computation time.
