ArrayFire ArrayFire, CUDA Leave a Comment

This is the fourth in a series of posts looking at our current ArrayFire examples. The code can be compiled and run from arrayfire/examples/ when you download and install the ArrayFire library. Today we will discuss the examples found in the image_processing/ directory. In these examples, my machine has the following configuration: ArrayFire v1.9 (build XXXXXXX) by AccelerEyes (64-bit Windows) License: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX CUDA toolkit 5.0, driver 306.94 GPU0 GeForce GT 650M, 2048 MB, Compute 3.0 (single,double) Display Device: GPU0 GeForce GT 650M Memory Usage: 1981 MB free (2048 MB total)... Image Demo The purpose of this example is to show how to do some common image manipulations. The method channel_split shows how easily multi-dimensional arrays can be subdivided: // Split a MxNx3 image into 3 separate channel ...

This is the first in a series of posts looking at our current ArrayFire examples. The code can be compiled and run from arrayfire/examples/ when you download and install the ArrayFire library. Today we will discuss the examples found in the getting_started/ directory. Hello World Of course we start with the classic "Hello World" example, which walks you through the basics of using the ArrayFire library. Running this example will print out system and device information, as well as perform some basic matrix operations. This is a good place to get familiar with the basic data container for ArrayFire - the array.
