Important:OpenCL was deprecated in macOS 10.14. To create high-performance code on GPUs, use the Metal framework instead. See Metal.

“OpenCL Programming Guide” was a nice introduction and also included useful summaries of data types and built-in functions that really helped. I started by creating a Mac OS X command line app in Xcode. Then I added the OpenCL framework. The OpenCL documentation on Apple’s developer site is brief and worth reading. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. For more information about OpenCL and how you use it, see OpenCL Programming Guide for Mac OS X. LemmycautioN macrumors member. Sep 29, 2008 84 0 Seattle.

OpenCL™ (Open Computing Language) is an open standard for cross-platform, programming of modern highly-parallel processor architectures. Introduced with OS X v10.6, OpenCL consists of a C99-based programming language designed for parallelism, a powerful scheduling API, and a flexible runtime that executes kernels on the CPU or GPU. OpenCL lets your application harness the computing power of these processors to improve performance and deliver new features based on compute-intensive algorithms.

In addition to support for the OpenCL 1.1 standard, OS X v10.7 adds integration between OpenCL, Grand Central Dispatch (GCD), and Xcode to make it even easier to use OpenCL in your application.

At a Glance

Using OpenCL is easier than ever as of OS X v10.7:

OpenCL is fully supported by Xcode. The Xcode offline compiler removes a configuration step that used to have to be performed before the kernel could be run and facilitates debugging earlier in the development process. See Hello World!.
You can write OpenCL functions in separate files and include them in your Xcode project. You can compile the kernels when your application is built, before it runs. This improves runtime performance.
OpenCL now integrates with GCD, making it easier for you to focus on making your OpenCL kernels more efficient. See Using Grand Central Dispatch With OpenCL.
The autovectorizer compiles and accelerates performance of kernels that run on the CPU up to four times without additional effort. The autovectorizer allows you to write one kernel that runs efficiently on both a CPU and a GPU. You can invoke the autovectorizer regardless of whether you are compiling from Xcode or building the kernels at runtime. Or you can disable the autovectorizer if necessary. See Autovectorizer.

You can, of course, continue to use code you’ve already written to the OpenCL 1.1 standard. But see Binary Compatibility Of OpenCL Kernels for a note about how to handle existing binaries.

Because OpenCL C is based on C99, you are free to process your data in OpenCL C functions as you would in C with few limitations. Aside from support for recursion and function pointers, there are not many language features that C has that OpenCL C doesn’t have. In fact, OpenCL C provides several beneficial features that the C programming language does not offer natively, such as optimized image access functions. OpenCL C has built-in support for vector intrinsics and offers vector data types. The operators in OpenCL C are overloaded, and performing arithmetic between vector data types is syntactically equivalent to performing arithmetic between scalar values. Refer to the The OpenCL Specification for more details on the built-in functions and facilities of the OpenCL C language.

Prerequisites

This guide assumes that you program in C and have access to The OpenCL Specification. Although this guide discusses many key OpenCL API functions, it does not provide detailed information on the OpenCL API or the OpenCL C programming language.

Actually, I primarily want to compile my own applications, and then test BOINC applications. So I started with BOINC itself. For now, I'm not building it from source, so I am using 7,1,17 which is, at the time I'm writing this, the current beta. I attached to a couple reliable + stable projects. So far, so good. :) I noticed that WUProp@Home either doesn't notice my Intel graphics (older server software?) or just doesn't query the onboard chip because there aren't any live applications using the intel_gpu plan class that I know of...yet. No point in collecting and aggregating data in a category for which there IS no data, I suppose. But PrimeGrid sees it! It looks like this, leading me to believe that OpenCL support is present by default in OS X 10,9. Perhaps that's because it's a development build? Before I even ask about applications in testing for Intel HD Graphics 4000/5000, I want to know if OpenCL is even a thing for OS X besides AMD GPUs. I've crunched tons of Collatz in the past on a farm of iMacs with AMD 6750Ms running OS X 10,7,5, but have had a very difficult time running NViDIA OpenCL apps (or cuda_opencl, or opencl_nvidia, or what have you) on this new MacBook Pro. I seem to remember running pure CUDA apps in the recent past, but from what I understand, the driver broke itself around April and there's still not a working version? I looked for OS X OpenCL drivers from/for Intel, but the closest I found was Linux (no specific distro, just 'Linux'). On the PrimeGrid page, where it's seeing Intel HD Graphics 4000 - is that BOINC beta reporting it, or OS X 10.9? Are the drivers even there? I don't see any tangible way to find out, since I don't know of any applications for OS X utilizing Intel graphics, and don't have the time or resources currently to go about trying to port the Linux drivers to OS X! If I'm getting way too ahead of myself, okay, how about this: I've got a 3770K in the mail (supposedly) and plan on building a system around it, even if just temporarily. That would run Windows, for which there are definitely Intel OpenCL drivers available. The only socket 1155 motherboard I have currently is a H67 chipset, and Z77 would probably be the best choice for a 3770K, I guess. (while I have your attention, any clues about NViDIA GT650M CUDA and/or OpenCL on OS X 10,8,4 or 10,9 would be appreciated... :))
