Almost all systems running on supercomputers are Linux, including those made up of Raspberry Pi Raspberry and PlayStation 3 consoles.Supercomputers are a serious tool, and they are all made up of tall calculations. They are often used for serious purposes, such as atomic bomb simulations, climate simulations, and advanced physics. Of course, they are also very expensive. In the latest supercomputer TOP500 rankings, China National Defense University of

Some critics of the Boda system are: Some voters may use this method to cheat (vote "tactical vote"), the candidate who most supports B is b>a>c, but because of the relative A, they prefer B, so in order to pull the B up, they have to pull A down, Their vote became a b>c>a. Boda's response to this criticism is that my system applies only to honest voters.
The author of this book thinks that the "tactical vote" problem of Boda is not so serious, if it is impossible to accurately predi

, the structure of the application SPE was set up at the early stage of development and various experiments were conducted. The high department said that because mgs4 did not consider the corresponding multi-platform, a large number of application SPEs were used. Therefore, the cell processor has been designed with an SPE from the very beginning. The principle adopted is to use the SPE implementation method to reduce the load if there is heavy load processing. Mgs4 does not have any technical b

Image Quality Comparison Test between fxaa and msaa
Next, let's look at the different picture quality between fxaa and common msaa by supporting fxaa's best BATMAN: argan city and glorious mission games. Because txaa has no actual product, we will not compare it today.
Test image quality settings
Due to human experience, fxaa (high) and msaa 4x have similar image quality. Therefore, we will compare the two settings. First, we will compare the image
