这个问题最初是基于韦尔斯利学院的参议院巴士。乘客来到公共汽车站，等待公共汽车。当公共汽车到达...，
This problem was originally based on the Senate bus at Wellesley College. Riders come to a bus stop and wait for a bus. When the bus arrives, all the waiting riders invoke boardBus, but anyone who arrives while the bus is boarding has to wait for the next bus. The capacity of the bus is 50 people.

使用CUDA并行语言编写的矩阵乘法，与串行语句的对比试验，主要检测出CPU与GPU运行的时间，通过比较时间，达到比较效果。另外此程序可以随意更改矩阵的维数，增强程序的移植性。
CUDA parallel language use matrix multiplication, and serial statement comparison test, the main test of CPU and GPU to run time, by comparing the time, to compare results. Also this program can change the dimension of the matrix, and enhanced portability of the program. (2014-12-09, Visual C++, 1KB, 下载20次)

利用CUDA实现了遥感数字影像处理基本算法中的拉普拉斯算子，并分别实现了采用Globalmemory、Sharedmemory，Texturememory进行数据传输，还同CPU中的串行代码进行了时间比较和误差分析。为了方便在服务器环境下测试运行，我们去掉了在Windows环境下对第三方库遥感影像库GDAL的依赖，而将遥感影像数据转成了二进制图像格式，对于输出影像也以同样的二进制格式存储。图像效果图通过专业遥感软件PCI或通用图像处理软件PhotoshopCS4打开。最后我们对计算结果进行了误差分析和加速比分析。
CUDA enables the use of remote sensing digital image processing the basic algorithm in the Laplace operator, and were achieved using Globalmemory, Sharedmemory, Texturememory data transmission, but also with the serial code CPU time comparison and error analysis. In order to facilitate the test run in the server environment, we have removed in the Windows environment for third-party remote-sensing image library GDAL library dependencies, but will switch to remote sensing image data into a binary image format, for the output images are also stored in the same binary format . Image Effect Picture through professional remote-sensing software, PCI or universal image processing software PhotoshopCS4 open. Finally, we calculated the results of the error analysis and speedup analysis. (2010-02-04, Unix_Linux, 3KB, 下载5次)
并行加法器是一种数位电路，其可进行数字的加法计算。在现代的电脑中，加法器存在于算术逻辑单元（ALU）之中。 加法器可以用来表示各种数值，如：BCD、加三码，主要的加法器是以二进制作运算。
Parallel adder is a digital circuit, which can be calculated the number of addition. In the modern computer, adder exists in the arithmetic logic unit (ALU) into. Adder can be used to express a variety of values, such as: BCD, plus three yards, the major is based on a binary adder for computing. (2010-01-13, VHDL, 3KB, 下载6次)

一个命令行运算器源代码
用C++写的命令行运算器，支持加、减、乘、除、乘方和小括号（可嵌套），乘方的符号是^^，因为在WINDOWS的命令行模式下^是一个连接符。
用法：cal expression
expression = expression op expression
expression = (expression)
op = + | - | * | / | ^^
a command line computing devices with source code written in C command line computing, and support for addition, subtraction, multiplication and addition. involution and small brackets (available nested), the involution is the symbol ^ ^. because of the Windows command line mode ^ website is a link. Usage : cal expression expression expression op = expr 34th expression = (expression) op = |- |* |/| ^ ^ (2006-06-18, C++, 162KB, 下载223次)
