Description

A kind of pattern process computer and construction method thereof

Technical field

The present invention relates to Internet technical field, particularly to a kind of pattern process computer and construction method thereof。

Background technology

Image procossing (imageprocessing), is analyzed image with computer, to reach the technology of results needed。Also known as image processing。Image procossing refers generally to Digital Image Processing。Digital picture refers to the big two-dimensional array obtained with equipment such as industrial camera, video camera, scanneies through shooting, and the element of this array is called pixel, and its value is called gray value。Image processing techniques generally comprise compression of images, strengthen and restore, coupling, describe and identify 3 parts。

Digital Image Processing is exactly utilize computer that image information is processed meeting the visual psychology of people or the behavior of application demand。Substantially one section can be shown by computer reduction and be output as the digital code of piece image。Image as the visual basis in the human perception world, is mankind's important means of obtaining information, expressing information and transmission information。Digital Image Processing [9], namely processes image with computer, and its developing history is not long。Digital image processing techniques come from the twenties in 20th century, transmitted a photos by submarine cable at that time, and have employed digital compression technology from London to USA New York。First digital image processing techniques can help that people are more objective, recognize the world exactly, the visual system of people can help the mankind to obtain the information of more than 3/4 from the external world, and image, figure are the carriers of all visual informations, although the resolving ability of human eye is significantly high, may identify which thousands of kinds of colors, but in a lot of situation, image is fuzzy or even sightless for human eye, pass through image enhancement technology, it is possible to make fuzzy even invisible image be apparent from becoming clear。On the other hand, by the mode identification technology in Digital Image Processing, it is possible to the image of human eye None-identified is carried out classification process。Can retrieve, mate and identify various thing rapidly and accurately by computer pattern recognition。

Graph rendering, English is Render, and being referred to as of also having is painted, but generally Shade is called painted, Render is called and renders。Because Render and Shade the two word is distinct two concepts in three-dimensional software, although their function is much like, but has difference。Shade is a kind of displaying scheme, is generally present in the primary window of three-dimensional software, the effect of playing auxiliary observation model the same as the line frame graph of threedimensional model。It is obvious that color mode is easier to let us than wire frame mode understands the structure of model, but it simply simply shows, is referred to as light and shade colouring in digital picture。As in the such advanced three-dimensional software of Maya, simple lighting effects, hatching effect and superficial makings effect can also be demonstrated with Shade, certainly, high-quality coloring effect needs specialty three dimensional graph display card to support, it can accelerate and optimize the display of 3-D graphic。But optimize in any case, it all cannot become the 3-D graphic shown into high-quality image, this is because what Shade adopted is a kind of real-time display technology, the speed of hardware limits the ray tracing effects such as reflection, the refraction that it cannot feed back in scene in real time。And we often to export into image file, video signal or cinematographic film model or scene in practical work, this is necessary for through Render program。

In prior art, specialty 3D graph rendering needs to carry out substantial amounts of floating-point operation and (includes physical entity, geometric transformation, shearing, light efficiency, and triangle setup) and integer arithmetic (including triangle setup and pixel rendering), it is a CPU intensive type task。Existing pattern process computer needs professional workstation, bulky, and price is high, and power consumption ability is superpower, is not suitable for general image procossing and graph rendering work。

Detailed description of the invention

Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention。

As it is shown in figure 1, a kind of pattern process computer structural representation provided for the embodiment of the present invention 1, including:

At least two pieces of cpu central processing units are respectively arranged at least two pieces of mainboards；At least two pieces of mainboards are connected to switch or router respectively with netting twine；Nfs server netting twine is connected with switch or router。

In the present embodiment, at least two pieces of described CPU, it is therefore intended that make multiple CPU collaborative work, thus at least need two pieces of CPU。CPU is The more the better in theory, it is possible to set the quantity of CPU according to the actual needs。

Set the quantity of CPU, it is clear that in order to coordinate the work of CPU, it is necessary to Cai there is corresponding mainboard passable。CPU must be mounted to just can play a role on corresponding mainboard。After the quantity set of CPU, the quantity of mainboard also just sets, the two be identical accordingly。

In the selection of mainboard, usual IQ needs to support the internal memory of 2G。Owing in the present embodiment, requirement for mainboard sets according to the actual needs, so this is not limited。

Set the quantity of CPU and mainboard, in order to be linked together by all of cpu motherboard, it will usually connected by netting twine。A switch or router is needed to connect to do total exchange between netting twine。The selection of switch or router, minimum needs are satisfied to be actually needed, and the mainboard quantity namely included according to real system selects。Such as, if real system includes 6 mainboards, then at least to select switch or the router of 8 mouthfuls。

In addition, in order to realize the actual control to system, in addition it is also necessary to a station server, for practical OS's。Nfs server can meet the demand of reality。

NFS is the abbreviation of NetworkFileSystem, i.e. NFS。A kind of agreement being used in decentralized file system, is developed by Sun Microsystems, outwards announces in 1984。Function is to allow different machines, different operating system can share an other data each other by network, allow application program be accessed the data being arranged in server disk by network in client, be between class Unix system, realize a kind of method that disk file is shared。

The basic principle of NFS is " allowing that different clients and service end share identical file system by one group of RPC ", and it is independently of operating system, allows that the system of different hardware and operating system carries out sharing of file jointly。

NFS depends on RPC agreement in file transmission or information transfer process。RPC, remote procedure call (RemoteProcedureCall) is a kind of mechanism that can make client executing other system Program。NFS itself is the agreement and function that do not provide information to transmit, but NFS can carry out sharing of data by network by let us, this is because NFS employs some other host-host protocol。And these host-host protocols use this RPC function。It may be said that NFS inherently uses a program of RPC。NFS is also a RPCSERVER in other words。As long as so the place using NFS will start RPC service, whether NFSSERVER or NFSCLIENT。Such SERVER and CLIENT could realize the correspondence of PROGRAMPORT by RPC。Can so understand the relation of RPC and NFS: NFS is a file system, and RPC is responsible for the transmission of information of being responsible for。

NFS promotes the archives on Servers can by other machine mount, and reach resource-sharing, the machine enjoying these archives just can be described as Client, one client can from mono-shelves of mount server or the catalogue (filehierarchies) of a level. but in fact any machine can be NFSserverorNFSclient, and even simultaneously can also for NFSserverandNFSclient。

Nfs server institute export archives out or catalogue all record in/these shelves of etc/exports, when we start NFSserver, this script at/etc/rc.local can start this formula of exportfs automatically, whether these shelves of search/etc/exports exist, and give correct authority to all export filehierarchies gone out。

The target of NFS is to allow the different machines can the identical Archive Resource of cross-platform sharing。In simple terms, it is possible to regard the archives economy of a kind of far-end as。Also because cross-platform target, so NFS all supported by almost all of UnixLike platform, such as IBMAIX, SunSolaris, HPUnix, GNU/Linux and FreeBSD etc., NFS can be passed through and share archives and resource of catalog。Although having NFSClient to install on MSWindows at present, but it it is almost business software。So everybody is everlasting, UnixLike system use NFS to share Archive Resource。Perhaps reader can wonder, why not shares with Samba net virtue, and such MSWindows and Unix can line mutually？This is because NFS efficiency ratio Samba is well a lot, so usually on the super computer of parallel calculation or business large scale system, using a NFSServer, other Server to be wired to NFS archive server through optical-fibre channel and obtain data。

Usually one NFSServer of frame in practice, and be fitted with magnetic tape controller can the backup archives of timing。Other server just gets up NFSServershare catalogue carry out, and the archives such as actually all webpages and data are all placed on NFSServer, these Server just only a simple computing with respond client request。Safeguard a archives economy as long as such benefit is for we, and backup and resource distribution also can be easier。Also because NFSServer generally uses Raid disc array system, so whole framework can reach high-effect and high reliability service。

So in the system of composition, it is possible to the operational capability making full use of multiple cpu motherboard carries out the image procossing of reality, or, it is also possible to doing other any work needing macrooperation amount, concrete application scenarios is not limited by the present embodiment。

As in figure 2 it is shown, the pattern process computer structural representation provided for the embodiment of the present invention 2, wherein,

This system includes 4 core processors of 6 pieces of Core2,6 pieces of Jijia's S series GA-G33M-DS2R/S2 mainboards, every piece of maximum 8GB internal memory of mainboard, it is placed in a big cabinet (six pieces of mainboards of system can be filled), fit together, form image procossing computer system。6 pieces of mainboards connect with 8 mouthfuls of 3com gigabit switch, then look for a computer to do nfs server。Thus achieve concrete pattern process computer hardware composition。

Then needing installation ubuntu12.04 system on nfs server, each mainboard passes through NFS NFS installation system。Installing type renders management software DrQueue in systems。

Drqueue is the Cluster Rendering management software of an open source code, supports that the task of Maya8 is submitted at present, and other support that software includes mentalray, shake, Renderman, and Blender3D。Drqueue has the Drkeewee service routine situation for the transmission rendering task that communicates, and these operate the stopping of rendering task such as through Drqman graphical interfaces, restart, priority level etc.。DrQueue can run on various platform (Linux, FreeBSD, Irix, MacOS-X&Windows) can also with the collaborative work under the graphic user interface of GUI of a lot of rendering engines (Maya, MentalRay, Blender, XSI, Lightwave, Mantra, Turtle, BMRT, Shake, AfterEffects, Aqsis, Nuke, Terragen, 3Delight and Pixie)。The script of DrQueue can be write。This software includes a little server DrKeewee, and by web browser, it can help you to check the situation of the pending data such as current。
