CAE solution Dawn based on blade server application

CAE is the computer Aided engineering design, since the 1960s CAE technology has been developed rapidly, its driving force is the growing industrial demand, including aerospace, energy and other fields are the powerful impetus for its development. At present, in aviation, aerospace, energy and other industrial fields, the use of CAE iterative design, analysis, optimization has become a standard must step and means. For example, the flow-solid coupling calculation of large and complex vehicle structures involves many disciplines such as computational aerodynamics, computational combustion, computational heat transfer and computational structural mechanics.

CAE Background knowledge

CAE is mainly divided into modeling, solution and post processing three steps, in which modeling and reprocessing is usually done in workstations, and CAE core is the solution process, need to occupy a large number of CPU, memory resources and storage space, usually to be completed on a high-performance computer. Commonly used CAE software mainly includes: Fluent,cfx,cfd-fastran/ace+,ansys,abaqus,msc Nastran,ls-dyna and so on.

CAE applications can be divided into two broad categories, one with shared memory applications represented by ANSYS,ABAQUS and Nastran structural analysis software, where the need for memory and storage I/O is very high for a single job, and usually in the process of computing will produce a large number of temporary storage but high performance requirements of the local Exchange file (Scratch), for this piece of performance optimization, can play a multiplier effect, otherwise, users buy expensive CPU memory efficiency will be greatly reduced, the other is fluent, CFX, Cfd-fastran, ace+ and other CFD software and Dyna, Pam-crash and other display structure analysis software for the representative of the distributed memory applications, this class of applications in parallel effect, the need for memory is not shared memory type of application large, And the local Exchange hard disk performance requirements are not high. Shuguang company CAE Field of professional engineers for these two types of applications detailed analysis of its characteristics, and the domestic well-known ISVs carried out a large number of joint testing, combined with the vast number of Shuguang user feedback valuable experience, launched the CAE High-performance computing platform solution.

TC2600 Blade +a950 SMP perfect combination to meet all types of application requirements

Shuguang Company proposed the design of CAE High-performance computing platform based on Blade server, which consists of 6 parts: 50-node TC2600 blade cluster, 2 a950r-f SMP minicomputer server, 2 a620r-f io node, SAN storage network, IP SAN storage networks and management nodes and graphics workstation areas.

Shuguang CAE High Performance computing platform

Shuguang CAE High-performance Computing Platform solution combines TC2600 blades and a950r-f SMP to meet the needs of various applications. The Dawning Blade server TC2600 is designed to break through the computer development bottleneck of increasing the scale of computer system and reducing the efficiency. It uses the ultra-high-density blade server architecture, built-in efficient network switching system, reduce network latency, super system processor expansion capability, maximum support for 20 AMD Opteron dual-core processor; excellent thermal design, break through 1U rack server space design limit, realize 7U 10-piece ultra-high density system design, through the overall design of the system, reduce unnecessary power consumption, effectively reduce the overall system power consumption, at the same time introduced the humanized design concept, everywhere embodies the people-oriented design idea, is easy to manage, easy maintenance, high availability of the next generation of server products. TC2600 is the dawning person in the server field of long-term commitment to computer technology research and another successful technical crystallization.
