【摘要】：高性能計算機作為提供云服務的基礎設施，在云計算核心業(yè)務中具有不可取代的地位。隨著云用戶規(guī)模不斷擴大，層次不斷提高，傳統(tǒng)高性能計算機服務模式已不能滿足和適應云用戶的服務需求。本文基于云計算應用模式，研究設計了面向云計算的高性能柔性服務平臺，該平臺可以按照用戶需求靈活配置運行環(huán)境，提供計算和軟件服務，滿足用戶對易用性、安全性、高效性、可定制性的服務需求。 針對云用戶對高性能計算資源的需求，設計了高性能計算柔性服務平臺架構，該平臺共包含三層。其中，基礎設施層主要是將擁有不同結構計算陣列的高性能計算機抽象為整體高性能計算服務，并且按照任務并行處理需要，根據(jù)現(xiàn)有系統(tǒng)資源，動態(tài)構建高性能用戶容器（HPUC）。平臺支持層主要是軟件的開發(fā)和運行環(huán)境，用戶通過該層提供的軟件開發(fā)工具，使用高性能計算機提供的各項遠程應用服務。用戶開發(fā)層主要為云用戶提供操作簡單、易用性好的胖客戶端開發(fā)平臺，并為用戶提供基于eclipse的網(wǎng)絡化圖形開發(fā)環(huán)境，從而提高云用戶的開發(fā)效率。 針對云用戶共享計算資源所帶來的安全性和可配置性問題，本文研究設計了高性能用戶容器（HPUC）技術，該技術基于操作系統(tǒng)層虛擬化技術，向用戶提供構筑獨立運行環(huán)境的支持，通過該運行環(huán)境，操作系統(tǒng)支持用戶可以按照自己的意愿靈活配置系統(tǒng)。同時，通過隔離相互環(huán)境隔離，，使一個HPUC中的錯誤操作不會影響其余HPUC運行。HPUC技術在操作系統(tǒng)層之上實現(xiàn)系統(tǒng)虛擬化，對系統(tǒng)性能的損失小，，整體性能損失小于3%，滿足了高性能并行計算機提供高效云計算服務的需求。 最后，本文從滿足HPUC負載均衡需求入手，研究實現(xiàn)了基于復合容器名的負載均衡技術，該技術按照任務并行處理需要，依據(jù)系統(tǒng)現(xiàn)有資源，動態(tài)構建高性能用戶容器，實現(xiàn)了系統(tǒng)服務效率最大化。同時，通過并行負載調度，用戶只需提出并行處理能力的要求，而無需關心提供服務的到底是哪個服務結點、計算陣列和存儲陣列，實現(xiàn)了將高性能計算以服務方式提供給云用戶的設計要求。
[Abstract]:As an infrastructure to provide cloud services, high-performance computers play an irreplaceable role in the core business of cloud computing. The traditional high performance computer service mode can not meet the needs of cloud users. Based on the cloud computing application model, this paper studies and designs a high performance flexible service platform for cloud computing. The platform can flexibly configure the running environment according to the user's needs, provide computing and software services, and meet the user's service requirements for ease of use, security, efficiency and customization. In order to meet the demand of cloud users for high performance computing resources, a flexible service platform architecture for high performance computing is designed, which consists of three layers. The infrastructure layer abstracts the high-performance computers with different computing arrays into the overall high-performance computing services, and according to the needs of task parallel processing, according to the existing system resources, The platform support layer is mainly the software development and running environment, through which users provide software development tools. Using various remote application services provided by high-performance computers, the user development layer mainly provides cloud users with a platform for developing fat clients with simple operation and good usability, and provides users with a networked graphics development environment based on eclipse. In order to improve the development efficiency of cloud users. In order to solve the security and configurable problem caused by cloud users sharing computing resources, this paper studies and designs a high performance user container (HPUC-based) technology, which is based on operating system layer virtualization technology. Provide users with the support to build an independent running environment, through which the operating system supports the user to configure the system flexibly according to his own wishes, at the same time, By isolating each other, the error operation in one HPUC will not affect the other HPUC running. HPUC technology to realize system virtualization on the operating system layer, and the loss of system performance is small. The overall performance loss is less than 3, which meets the demand of high performance parallel computers to provide efficient cloud computing services. Finally, starting with the requirement of HPUC load balancing, this paper studies and implements the load balancing technology based on the compound container name. According to the need of task parallel processing, this technology dynamically constructs the high performance user container according to the existing resources of the system. At the same time, through parallel load scheduling, users only need to put forward the requirement of parallel processing ability, and do not care which service node, computing array and storage array provide the service. The design requirements of providing high performance computing to cloud users are realized.
