/specs/liberty/approved/robustify_evacuate.rstGlance new features Automatic conversion of image format, for example, Ceph is using RAW format, if we upload QCOW2, create a virtual machine, we will experience a upload download process, the speed is unusually slow. And the raw format is usually the original size, upload time is very slow, completely can be uploaded by the small image automatically converted to the specified format. Glance s

address the operational automation of the production environment, followed by the container build problem (i.e., CI/CD). Our network selection is flannel, million trillion network, flannel although there is performance loss, but far to meet our actual needs. Storage we use Ceph's RBD way, for more than a year, RBD's program is very stable. The way Ceph FS is we have tried, but it has not been formally used due to limited team effort and possible risk

A ganglia monitoring is installed for Ceph, as follows. 1. Environmental statementCeph is the 3 physical machines installed on the centos6.5: Mon0, OSD1, OSD2, so you need to install Gmond on all three machines, OSD2 on Gmetad. 2.

Many users want to modify the graphics card Control Panel settings to improve the performance of the graphics card, but when you see a professional terminology, it is prohibitive. Let me tell you today how to set up the Nvidia graphics Control Panel. I won't tell you what to do with the drive. Let me take my own example. First system diagram: Right on the desktop, click on the Nvidia Control Panel, see the figure below (manual shutdown of the 3D display, so most users can also see

Article title: Intel was found to be cheating on 3DMark. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Image-driven performance optimization for specific applications is regarded as a kind of cheating. of course, the current driver's optimization for the game is very popular among players. if it can improve the game experience, why? But what do you think i

different from farts.So I need to write a relatively long article to explain the content and characteristics of the book, popular so that you can read other social information as easy to read, do not need much thinking and understanding, and space needs to be long enough to introduce the content and characteristics of the book coverage. Happened in Baidu Bar "Crysis" see an article want to understand the characteristics of various global lighting tec

Texture and UV Expansion The texture size applied to an object depends on the area size and quantity of the object displayed on the plane. For crysis, the screen resolution set by crytek is 800x600, assuming that the object fills the average screen height at any time (600/2 = 300 pixel ); therefore, we need to use a texture resolution of at least X. It would be better to use 512x512. The best case is that each pixel on the screen represents an eleme

there are few adult masters, because they lack the environment to grow into masters. 3. With the support of the creation team, if you think that you can build a car by yourself for years, you will be wrong. In the era of programmable pipelines, it is not difficult to create a simple rendering framework to achieve several Amazing effects. The effect will be cool for a few days, adjust the rendering process, and then write a few small shader. Post Effect is much easier, and it is enough to implem

, if we build a new architecture like this, it will be more troublesome for the real-time user. He needs to write a compiler by himself. Otherwise, if the driver is built on the program, it will be almost unnecessary to change the shader compiler, each vendor can use the same one, because the key is to compile the program. In addition, Meta format similar to d3d hlsl fx does not exist. I can do this myself. God, but what about compatibility? Your product can run on Windows, Linux, or Mac. Even t

Mark spoke. Source of the original article. Summary:1. It is unrealistic to expect ray tracing to replace Rasterization in the next era, Unless intel uses the processor performance heap (Larrabee, I don't expect it, not to mention the processor design, however, developers are not well trained ).2. Do not make sense of the effect, and make a "good-looking" effect is the right way for the game (blog arguments: halo3 vs bioshock or halo3 vs crysis ).3

Windows 8.1 system has not yet been formally released, Samsung Ativ Q is currently only equipped with a preview system and we have not performed a full performance test. We tried to run the Crysis 3 game, and Samsung Ativ Q was able to play more smoothly in low-quality images. Cooling, 100% of the processor operating temperature is basically less than 28 degrees Celsius, but in the flat mode, due to the cooling hole is obscured, the fuselage surface

the above 4 points, and then the second time you need to understand is: 1.400 yuan, 600 yuan, 800 yuan and 1000 yuan graphics card, although you do not understand between them in the flow processing unit, bit width, the voltage difference, but the price determines the performance, this is the most real. Buy 400 yuan graphics card also requires Crysis 3 to be able to effect full open no "slide", this and to buy a permanent bike God is four rings as i

officially entered into the pixel coloring device for illumination calculation. All of the above is described when the camera is out of the illumination range.AlgorithmWhen the camera is under a certain illumination range, you only need to simply draw the backface of the surrounding body. Blizzard put a complex light source diagram as follows. We can imagine how complicated our shader and illumination range judgment would be if we were using traditional rendering methods.

: Triangle stage-> triangle traversal-> pixel shading-> Merging Summary This is not the only form of rendering assembly line. When movie rendering is usually used, micro polygon pipelines, academic research and predictive rendering usually use light Chase, now some rendering tools also use the ray tracing Renderer, such as blender. The OpenGL rendering pipeline is shown in: Generally, the hardware rendering pipeline is fixed, such as Nintendo's Wii, but today's programmable GPU brings us anothe
