Description

TECHNICAL FIELD

[0001] The present application relates to the field of computer, in particular, to a method and system for performance enhancement of computing system under certain conditions. BACKGROUND

[0002] The ruggedized blade computer designed based on VPX bus standard is usually composed of blades and chassis (including backplane) that realize various functions. Generally, a chassis needs to contain power supply blades, switching blades and computing blades to realize the function of data interaction with the outside world and relatively independent work. The size of the blade includes 6U and 3U. The chassis size corresponding to the 6U blade is usually 8U or 10U, and the chassis size corresponding to the 3U blade is usually 5U. The basic structure of the small blade computer designed based on VNX bus standard is similar to the ruggedized blade computer designed based on VPX bus standard. The size of the blade panel used is significantly smaller than that of the 3U blade, and the panel area is about half of that of the 3U blade, which is divided into 19mm and 12.5mm two thicknesses. The VNX chassis uses fanless cooling, so the power consumption limit of the blade is more obvious, but at the same time, the size of the VNX chassis is significantly smaller than that of the chassis designed based on VPX standard when using the same number of blades.

[0003] The distributed computing system composed of multiple VPX-based blade computers connected by cables. Such system considers the use scenario conditions and adopts a distributed structure in the design stage. Only VPX standard is used in a single system, and the size of the blade is usually unified as 6U or 3U, which is convenient for later maintenance.

[0004] Some systems are designed as single VPX chassis in hardware in the design stage, and the types of blades included in the system are determined. For example, the processors used in computing blades include CPU, GPU and DSP. Under the current application software requirements, it can meet the corresponding specific use scenarios. With the continuous updating and development of algorithms in application software in this use scenario, it will be difficult to meet the efficiency requirements of some special computing by using only the processor types contained in the existing computing blades. It is necessary to introduce other structures of processors such as NPU to realize more efficient computing.

[0005] For the above problems, one solution is to design computing blades with the same bus standard according to the corresponding requirements, pull out and replace some computing blades originally running in the chassis with newly designed computing blades; this solution keeps the overall computing system size unchanged and the weight basically unchanged, but it will inevitably affect the processing of the entire computing system for the current application during the process of plugging in and out the computing blades. Another way is to add a chassis of the same model computer, connect the newly added chassis of the same model with the expansion interface reserved for the exchange blade on the original computer, equip the newly added chassis of the same model with the same power blade, exchange blade and newly designed computing blade, and update the software accordingly to meet the current architecture requirements; this solution can effectively avoid the changes of the original chassis caused by the plugging in and out of the blades in the first solution, thereby avoiding the damage to the processing of the original computing system for the current application, but its disadvantage is that it adds a chassis of the same model, which requires about 2 times the physical space in the original working environment, and the weight of the entire computing system will be close to twice that of the original system. In the original working environment, there may not be enough physical space, and if the computing system is mounted on a mobile platform such as a vehicle, a ship or an aircraft, the significantly increased weight will significantly reduce the performance of the entire working system.

[0006] Patent document CN1183150A (application number: CN96193648.7) discloses a method and device for enhancing the performance of a processor, comprising: setting an optimal processing frequency for the processor according to the operating characteristics of each processor. The power supply voltage supplied to the processor is artificially or under software control to increase to the maximum value specified for the processor. This allows the processor to operate at the maximum possible frequency. The processor clock frequency varies relative to the mainboard clock frequency, so that the processor clock can be arbitrarily set at its maximum operating frequency. An approximation method is used to determine the maximum clock frequency at which the processor will operate normally. To prevent thermal-induced semiconductor damage, additional heat dissipation and / or thermal management methods are performed. The power supply voltage can also be combined with clock rate control to determine the optimal operating frequency and supply voltage to the processor. However, this invention does not design to enhance the performance of the computing system based on the VNX standard. SUMMARY

[0090] Embodiment 3:

[0091] Embodiment 3 is a preferred example of Embodiment 1, which more specifically illustrates the present application.

[0092] The present application combines the limitations of the working environment of the computing system in physical space and weight with the enhancement requirements of the computing system, and designs and accesses the computer based on the VNX standard on the basis of the original computer based on the VPX standard, as shown in Figure 1 The method mainly includes four steps.

[0093] Step 1 is the analysis of the limitations and enhancement requirements. This step mainly needs to complete the following three works: analyzing the use environment of the computing system, finding out the available space that can be inserted into the small size case and clearly allowing the increased weight limit; counting the number and type of available expansion interfaces of the original computing system; clearly specifying the specific performance enhancement requirements, such as NPU acceleration capability.

[0094] Step 2 is the design or modification of VNX case and blade. The work of this step is mainly based on the analysis results of step 1. Based on the three factors of the number of available expansion interfaces of the original computing system, available space, and allowed weight increase, the number and size of the VNX case are determined. In some cases, the available space shape is irregular, and in the case of allowing the number of expansion interfaces, a combination network formed by multiple VNX computer cases containing a small number of blades and small size can be used to meet the corresponding performance requirements. According to the type of available expansion interface of the original computing system, the type of external interface of the VNX case is determined, so as to determine the type of VNX exchange blade. According to the performance enhancement requirement, the corresponding VNX-based computing blade is designed and the total number of computing blades used is specified.

[0095] Step 3 is functional performance, six performance and electromagnetic compatibility evaluation and test. The functional performance test is mainly aimed at testing the weight, volume, computing performance, acceleration capability or other performance enhancement indicators required to be provided by the newly designed computer. Single computer test and online test combined with the original computing system can be designed to verify whether the newly designed computer meets the functional performance requirements so as to meet the space, weight limit level performance enhancement requirements obtained in step 1. The six performance (reliability, maintainability, supportability, testability, safety and environmental adaptability) evaluation and test requirements of the newly designed computer should be similar to those of the original computing system, so that the newly designed computer can meet the specific work requirements of the computing system in terms of six performance. The items tested in the electromagnetic compatibility test should be the same as those of the original computing system, so as to ensure that the electromagnetic compatibility of the entire computing system after the newly designed computer is connected can meet the requirements of the application environment. If there are unpassed items in the above evaluation and test, corresponding design modification is required, and then the corresponding evaluation and test are performed again. After passing, the newly designed computer can be connected with the original system.

[0096] Step 4 is installation and software update. The newly designed VNX computer case is connected with the expansion interface of the original computing system case through a cable, and the VNX computer case is fixed in the use environment according to the predetermined design. If necessary, the software of the original computing system exchange blade is updated, so that the task allocation function of the original computing system exchange blade can allocate the corresponding task of the performance enhancement requirement to the VNX computer, and correct data interaction is realized.

[0097] Through the above steps, the specific performance enhancement of the computing system under the limited conditions can be realized.
