C32 computing power

1.

It includes CUDA instruction set architecture (ISA) and parallel computing engine in GPU. Developers can now use C language to support CUDA; Architecture programming, C language is the most widely used high-level programming language. The program can then support CUDA & 8482; Runs at ultra-high performance on the processor. Other languages, including FORTRAN and C + +, will be supported in the future

with the development of graphics card, GPU becomes more and more powerful, and GPU optimizes the display image. It has surpassed the general CPU in computing. If such a powerful chip is only used as a graphics card, it would be too wasteful. Therefore, NVIDIA launched CUDA, which enables the graphics card to be used for purposes other than image computing

At present, only NVIDIA graphics cards on g80, G92, G94 and GT200 platforms can use CUDA, and the core of the toolkit is a C language compiler. G80 has 128 separate ALUs, so it is very suitable for parallel computing, and the speed of numerical calculation is much faster than CPU

The compiler and development platform in CUDA SDK support windows and Linux systems, and can be integrated with Visual Studio 2005

at present, this technology is in its infancy, which only supports 32-bit system, and the compiler does not support double precision data, which will be solved later. Geforce8cuda (Compute Unified Device Architecture) is a new infrastructure, which can use GPU to solve complex computing problems in business, instry and science. It is a complete GPGPU solution, which provides direct access interface to hardware instead of relying on graphical API interface to achieve GPU access

in the architecture, a new computing architecture is adopted to use the hardware resources provided by GPU, which provides a more powerful computing power than CPU for large-scale data computing applications. CUDA uses C language as programming language to provide a large number of high-performance computing instruction development capabilities, which enables developers to build a more efficient data intensive computing solution based on the powerful computing power of GPU< br />

2. If you don't know anything about permutations and combinations, don't think about formulas. Just figure out C and A. C32 is to take two out of three. You can think about how many kinds there are, and there are only three possibilities

3.

The result is 3

C (n, m) = P (n, m) / P (m, m) = n/ m! n-m!

can be obtained: C32 = 3

extended data:

m elements can be repeatedly selected from n different elements. It is called repeatable combination of M elements from n elements to synthesize a group regardless of its order. If and only if the elements taken are the same and the times taken by the same element are the same, then the two repeated combinations are the same

The calculation method of

permutation is as follows:

permutation a (n, m) = n × n-1 n-m+1=n!/ n-m!( N is subscript, M is superscript, the same below)

combination C (n, m) = P (n, m) / P (m, m) = n/ m! n-m!

for example:

A (4, 2) = 4/ 2!= 4*3=12

C(4，2)=4!/( 2!* 2!)= 4*3/(2*1)=6

4. If there are n lines, the n-th power of 2 is equal to its addressing space, so you can calculate that the power of 2 is 32g, which should be 35

When I happened to look at Zhihu, I saw such a sentence: "in this age of data king and traffic supremacy, there is no time when it is easier to manipulate a person's nerves than now." Indeed, whether we admit it or not, information flooding has become the most prominent feature at present. Therefore, a star or a company in the spotlight can quickly get attention from the outside world once they master how to create "topics"

?

in a word, it can be predicted that the competition between Tesla and Xiaopeng will continue, and in this process, the mutual connection between musk and he Xiaopeng may also appear again. But just as he Xiaopeng said when Xiaopeng entered the "New York Stock Exchange" this year, "in the past six years, we have done a bold thing. We have always firmly believed that intelligent cars are the future. Today, Xiaopeng automobile has entered a new stage. After this step, we will have more food, more trust and more support to meet the real arrival of the era of intelligent vehicles. "

It must be admitted that the era of more pioneers has come. Although Tesla is still strong, the new brands like Xiaopeng are becoming more and more confident. In the end, everyone is ushered in a new auto market with rapid technology iteration and earth shaking changes
