1. Global memory In cuda, the general data is copied to the memory of the video card, which is called global memory. These memories do not have cache, And the latency required for accessing global memory is very long, usually hundreds of cycles. Because global memory does not have a cache, a large number of threads must be used to avoid latency. Assuming that a large number of threads are executed simultaneously, when a thread reads the memory and starts waiting for the results, the

Ubuntu16.04 ultra-low graphics card GTX730 configuration pytorch-gpu + cuda9.0 + cudnn tutorial, gtx730cudnnI. Preface Today, I have nothing to do with the configuration of the ultra-low-configuration graphics card GTX730. I think it may be possible to use cuda + cudnn for all the graphics cards. As a result, I checked it on the nvidia official website. It's a pity that I have a large GTX730 ^, so I can use cuda for 730. There are many blog posts abou

When I went to the bookstore today to issue an invoice, I accidentally found that the GPU gems 2 Chinese version was released. This time, it was published by Tsinghua University Press, with full-color printing. Of course, the price is expensive. The price for 565 pages is 128 RMB ~~ I bought the product at a discount of 100 yuan, but I cannot report it to you ~~~ I opened it and looked at it. The books of Tsinghua University Press are really not aver

Welcome¶Theano is a Python library that allows your to define, optimize, and evaluate mathematical expressions involving multi-dime Nsional arrays efficiently. Theano Features: tight integration with NumPy –use numpy.ndarray in theano-compiled functions. Transparent use of the A GPU –perform data-intensive calculations up to 140x faster than with CPU. (float32 only) Efficient symbolic differentiation –theano Does your der

Caffe allows parallel computing between multiple GPU, and multi-GPU mode is "not sharing data, but sharing network". When the number of GPU on the target machine is greater than 1 o'clock, Caffe will allow multiple solver to exist and be applied to different GPU. Vector The first solver will become Root_solver_, and

in the game Bull quiz often ask questions about the shader programming aspects of unity, GPU programming is to put the fixed pipeline of various matrix transformation into the GPU.

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
