Abstract
The invention discloses a method for improving the cloud application property via non-transparent CACHE. The method is that the physical internal memory is divided into a system internal memory and a non-transparent CACHE when a cloud computing server is started, wherein the system internal memory is distributed to each virtual machine by a public resource distributor in a cloud OS; and the non-transparent CACHE is distributed to the cloud application for use in the virtual machines by a non-transparent CACHE resource distributor. By adopting the method provided by the invention, the internal memory is preserved as the CACHE resource of the cloud application when a BIOS is started, the cloud application can direct access the resource without via an operating system of a cloud computing server, so that the access paths is reduced, and the property of the cloud application is improved.
Description
Technical field
The present invention relates to computer realm, be specifically related to a kind of method that improves the cloud application performance through nontransparent CACHE.
Background technology
At present generally adopting the unified resource allocation scheme aspect the resources allocation of cloud computing system, do not having to adopt special resource distribution mode to some special application.Such as adopting CACHE at a high speed to quicken memory property to the storage application need.If adopt the universal and uniform resource allocation methods if this type of picture used; Then cloud is used and will be passed through cloud to the operation of CACHE and use a plurality of links such as operating system that virtual machine, virtual machine moved of being moved and could realize the operation to actual CACHE; This has increased the operational access link undoubtedly; Delay operating speed, reduced the performance of using.
Summary of the invention
The purpose of this invention is to provide and a kind ofly proposed a kind of method through nontransparent CACHE raising cloud application performance to the existing deficiency of cloud computing system aspect resources allocation.
The objective of the invention is to realize that by following mode step is following: when cloud computing server starts, physical memory is divided into Installed System Memory and nontransparent CACHE two parts; Installed System Memory is distributed to each virtual machine by the public resource divider among the cloud OS; Nontransparent CACHE uses use by the cloud that the nontransparent CACHE resource allocator among the cloud OS is distributed in the virtual machine;
The internal memory that Installed System Memory is distributed to each virtual machine use through the public resource divider is transparent internal memory, and the operating system in cloud OS and virtual machine is managed, and supplies the operating system in the virtual machine to distribute use;
It is special-purpose CACHE that cloud is used employed nontransparent CACHE, and the system in cloud OS and virtual machine manages, and uses and use direct control by cloud;
Nontransparent CACHE resource allocator only is used for the distribution of resource and does not participate in the management of nontransparent CACHE, after distributing to the cloud application, just gives cloud with the management right to use of this CACHE resource and uses.
Method of the present invention is distributed the physical memory resource when BIOS starts, and is divided into Installed System Memory (the following stated " Installed System Memory " is refered in particular to the Installed System Memory that BIOS independently marks off, but not whole physical memory) and nontransparent CACHE internal memory.Installed System Memory is to supply the cloud computing operating system in the cloud computing server to use, and nontransparent CACHE supplies special cloud to use to use.
BIOS in this invention is a notion widely, can refer to the BIOS of X86 computing machine and server, can refer to that also the BOOT of non-X86 system starts or guidance code.Be used for accomplishing system start-up preceding initialization and guiding work.
It is transparent to it that cloud OS in cloud computing server starts the back Installed System Memory, also is the Installed System Memory that cloud OS can see and use BIOS to distribute.
Start the back Installed System Memory at cloud OS and distribute to each virtual machine on the cloud OS, as the memory source use of each virtual machine through the public resource divider.
Nontransparent CACHE is nontransparent to the virtual machine on cloud OS and the cloud OS, also is that the virtual machine itself on cloud OS and the cloud OS cannot use nontransparent CACHE.
Can use for cloud after nontransparent CACHE distributes through nontransparent CACHE resource allocator and use.After obtaining the right to use of nontransparent CACHE, cloud is used and can directly used nontransparent CACHE and manage without the participation of the operating system of virtual machine and cloud OS.
Method through nontransparent CACHE raising cloud application performance of the present invention is compared with prior art; It is the shortest to the access path of nontransparent CACHE that the present invention can make cloud use; Reduced the transmission time-delay of intermediate link; Can quicken the performance that special cloud is used, thereby, have good value for applications.
Description of drawings
Fig. 1 is the system diagram of method involved in the present invention;
Fig. 2 is nontransparent CACHE access path figure.
Embodiment
Explanation at length below with reference to Figure of description method of the present invention being done.
The method that improves the cloud application performance through nontransparent CACHE of the present invention like accompanying drawing 1, is divided into Installed System Memory and nontransparent CACHE two parts with physical memory when cloud computing server starts; Installed System Memory is distributed to each virtual machine by the public resource divider among the cloud OS; Nontransparent CACHE uses use by the cloud that the nontransparent CACHE resource allocator among the cloud OS is distributed in the virtual machine.
The internal memory that Installed System Memory is distributed to each virtual machine use through the public resource divider is transparent internal memory, and the operating system in cloud OS and virtual machine is managed, and supplies the operating system in the virtual machine to distribute use.
It is special-purpose CACHE that cloud is used employed nontransparent CACHE, can manage without the system in cloud OS and the virtual machine, uses and use direct control by cloud.
Nontransparent CACHE resource allocator only is used for the distribution of resource and does not participate in the management of nontransparent CACHE, after distributing to the cloud application, just gives cloud with the management right to use of this CACHE resource and uses.
The access path that accompanying drawing 2 is used for cloud, common internal memory operation will pass through cloud application, cloud application virtual machine, Cloud Server OS, physical memory four processes.Access path of the present invention can directly realize being applied to the visit of internal memory.
Embodiment
Cloud storage applying step is following:
1) accomplishes the division of nontransparent CACHE by system bios;
2) cloud OS starts and moves nontransparent resource allocator;
3) cloud OS gives the cloud storage virtual machine according to the required public resource of the resources allocation of customization, is used to start the cloud storage virtual machine;
4) the cloud storage virtual machine starts the back and starts cloud storage application, and the cloud storage is used through specific resource bid mechanism through the nontransparent CACHE resource of cloud storage virtual machine application;
5) after the nontransparent CACHE resource of acquisition, the cloud storage is used it is carried out data-storage applications as high speed storing CACHE;
6) with the shortest access path: be applied to CACHE or CACHE and data carried out accessing operation to using;
7) finish using the back nontransparent CACHE signal of cloud application transmission release to nontransparent CACHE explorer;
8) nontransparent CACHE manager discharges nontransparent CACHE.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
