OpenCL on Intel HD / Iris graphics on Linux

Brian Kloppenborg OpenCL 17 Comments

Under Windows and Mac the Intel GPU drivers include OpenCL support; however, on Linux OpenCL on Intel GPUs is implemented through an open source project called Beignet (pronnounced like "ben-yay", a type of French pastry akin to a what we would call a "fritter" in English). Below I have written a step-by-step guide on how you can get Beignet running on an Ubuntu 14.10 system which has an Intel 3rd, 4th, or 5th generation Intel processor. Instructions for other variants of Linux will be similar, except for the commands to install the prerequisite packages. There are several little caveats which need to be discussed up front. Foremost, the Beignet project supports the following hardware: 3rd Generation Intel Core Processors Intel ...

ArrayFire Reception in France

As an engineers company, we spend a lot of time wrestling in the weeds of low-level GPU and accelerator codes. This is our battleground, and it can often be dizzying in its complexity. Our whole purpose is to hide that mess and tame those low-level beasts so that ArrayFire users get better performance than anyone else. The joy of ArrayFire comes when we get feedback from ArrayFire users, often from different parts of the world. For instance, the week I share excerpts from two recent emails we received in France: 1) From Barep, a French manufacturing company:  "I think ArrayFire is a 'must have' library. It's very easy to use and can be used under Linux and Windows. Personally, I'm happy ...
