I have been trying to read this article before. I have read it today and I have had some gains: 1. After clustering documents by similar terms, Delta is small, which can improve the compression ratio (similarity graph) 1. GPUs generally have hundreds of cores, including shared memory and global memory. Shared Memory is equivalent to the Register speed, and global memory is slow. 2. Search Algorithms on Ordered arrays include binary search and interplation search (Interpolation Search). The av

Users who do not support OpenCL graphics cards can use multi-core CPUs for OpenCL computing, which is still faster than the original C # version.

At today's Microsoft developers conference (Microsoft PDC 2009), Microsoft demonstrated the next version of IE-ie9. One of the highlights of ie9 is thatDirectX(Direct2d, directwrite) andGPU hardware accelerationTo create a revolutionary browser rendering engine ). Its advantages are obvious: SpeedFast, HD. 1. Fast As we all know, DirectX and GPU hardware acceleration have been used for high-performance, high-complexity game engines. Ie9 revolut

previous firegun, it takes a shot to charge a gun before it can be shot. Each access time is-clock (core clock) latency. In Cuda programming, memory access is one of the bottlenecks. The bandwidthtest provided by the SDK can be used to test the transmission performance from the host to the device, from the device to the host, and from the device to the device. Although PCIe has a theoretical value of 3.2 Gbit/s, it does not actually reach that much. Device to device transmission can reach about

anti-tooth (fast approximate anti-aliasing) It is a high-performance approximation of the traditional msaa (Multi-sample anti-aliasing) effect.. It is a one-way pixel coloring tool that runs in the post-processing stage of the rendering pipeline of the Target game like MLAA, but does not use directcompute as the latter, but simply a post-processing coloring tool, does not rely on any GPU computing API. Because of this, fxaa technology has no special

GPU deep mining (II): OpenGL framebuffer object 101Author: by Rob 'phantom '; Jones Translator: 文 updated: 2007/6/1IntroductionFrame Buffer object (FBO) extension, which is recommended for rendering data to a texture object. Compared with other similar technologies, such as data copy or swap buffer, using FBO technology is more efficient and easier to implement.In this article, I will quickly explain how to use this extension, and introduce some thing

A server is loaded with multiple GPUs, and by default, when a deep learning training task is started, this task fills up almost all of the storage space for each GPU. This results in the fact that a server can only perform a single task, while the task may not require so many resources, which is tantamount to a waste of resources.The following solutions are available for this issue.First, directly set the visible GPUWrite a script that sets environmen
