    Considered in this article are various aspects associated with the implementation of large-scale supercomputer calculations of hydrodynamic and aeroacoustic problems; the problems of computational optimization are considered. Given are the means of achievement of high parallel efficiency for a large number of processors (up to several thousand). The implementation features of architecturally adapted hybrid paralleling, the optimization of memory access, and parallel processing of computational data and large grids are described. Given here are examples of direct numerical simulation applications for the simulation of both compressible and incompressible turbulent flows with the use of high-accuracy numerical algorithms on structured and unstructured grids.
    The development of supercomputer is very fast,not only the speed changes with each passing day,but also the structure becomes more and more complicated and diversiform.In order to describe supercomputer's structure rightly and availably,and give the uniform description method,this paper brings forward the multi-level structure and description of supercomputer.It can ground in farther abstracting or programming supercomputer simulator and help to design supercomputer system.

    According to the increasing demands of supercomputer, an exclusive supercomputer building is requested to install a supercomputer for promoting high-end R&D as well as creating the public service infrastructure in the national level. KISTI, as a public supercomputer center with the 4th supercomputer (capacity of 360Tflops), is experiencing shortage of infrastructure systems, caused by increased capacity. Thus, it is anticipated that the situation will be growing serious when the 5th and 6th supercomputers will be installed. On this study, analyzed on the 5th supercomputer system through projecting performance level and optimal operating environments by assessing infra-capacity. Explored way to construct optimal operating environments through infrastructure-capacity analysis of supercomputer center. This study can be of use for reviewing KISTIs conditions as the only supercomputer center in Korea. In addition, it provides reference data for planning the new exclusive supercomputer center in terms of feasibility, while analyzing infrastructure systems.

    High Performance Computing is now one of the emerging fields in computer science and its applications. Top HPC facilities, supercomputers, offer great opportunities in modeling diverse processes thus allowing to create more and greater products without full-scale experiments. Current supercomputers and applications for them are very complex and thus are hard to use efficiently. Performance monitoring systems are the tools that help to understand the efficiency of supercomputing applications and overall supercomputer functioning. These systems collect data on what happens on a supercomputer (performance data, performance metrics) and present them in a way allowing to make conclusions about performance issues in programs running on the supercomputer. In this paper we give an overview of existing performance monitoring systems designed for or used on supercomputers. We give a comparison of performance monitoring systems found in literature, describe problems emerging in monitoring large scale HPC systems, and outline our vision on future direction of HPC monitoring systems development.

    Предложен метод проведения анализа эффективности и оптимизации суперкомпьютерных приложений, примененный на практике для изучения задач одного из пользователей суперкомпьютера Ломоносов2. Этот метод затрагивает различные этапы исследования задач, начиная от изучения общего поведения всех запусков пользователя на суперкомпьютере и заканчивая детальным изучением и оптимизацией исходного кода выбранной программы. Приведено описание общих этапов анализа, которые были выполнены на практике, показаны метрики производительности, на которые следует обратить внимание при выполнении подобного анализа, а также продемонстрированы конкретные примеры поведения задач и эффект от оптимизации, выполненной для задачи расчета жидкокристаллических капель. A method for the efficiency analysis and optimization of supercomputer applications applied earlier in practice to study jobs of a user on the Lomonosov2 supercomputer is proposed. This method involves various stages of the jobs research, starting from studying the general behavior of all user launches on a supercomputer and ending with a detailed study and optimization of the source code of a selected program. The paper describes the general stages of the analysis that were carried out in practice, shows performance metrics that should be paid attention to when performing such an analysis, and shows also some specific examples of the job behavior and the effect of optimization carried out for the task of calculating liquid crystal droplets.

    The next generation supercomputer R & D project started from January, 2006. The Supercomputer will start operation in April, 2011 and will be enhanced its performance during F.Y.2011. It is currently on the progress of design work and its effective performance is planed as > 1.0 Peta FLOPS. As the Earth simulator, this supercomputer will be fastest and larges in Japan and it will be very difficult for other supercomputer to process and visualize the computed results on it. Therefore, we are planning to have an attached visualization system.
