I found this link with drivers and runtimes.
And also as per this , OpenCL codebuilder is now part of INDE/Media server Studio and these are not free (Though they come with trial version)
So my ultimate question is how to get started with OpenCL with Intel HD Graphics?
There is a starter edition of the Intel INDE suite, which is free (and is not just a trial). This contains their core OpenCL SDK. The Media Server Studio may contain some additional tools to aid OpenCL development on Intel HD Graphics, but is certainly not required in order to develop or run OpenCL programs.
You don't actually need any OpenCL SDK to get started with OpenCL development. You need a driver/runtime in order to run OpenCL programs (these are freely available, as per your first link). To develop OpenCL programs you just need the headers and a library to link against, which are both also freely available (more info in this answer).
Which programming language would you like to use? In Java you can start with a simple Java SE application and integrate the JavaCL package. You do not need any further vendor specific drivers.

I have a non-Android Embedded system which uses Embedded Linux based OS. It has a Mali GPU and I need to profile GPU performance. Some options were DS5 Streamline and Mali Graphics debugger, but it seems tailored for Android (with adb). Is there any generic GPU profiling tool which I can use?
Streamline (DS version) does support Linux-based targets. On the Streamline documentation page you'll find near the bottom a link to the doc for setting up a Linux-based target.
I'v been trying for the past day to get Tensorflow built with OpenCL on the Linux Subsystem.
I followed this guide. But when typing clinfo it says
Number of platforms 0
Then typing /usr/local/computecpp/bin/computecpp_info gives me
OpenCL error -1001: Unable to retrieve number of platforms. Device Info:
Cannot find any devices on the system. Please refer to your OpenCL vendor documentation.
Note that OPENCL_VENDOR_PATH is not defined. Some vendors may require this environment variable to be set.
Am I doing anything wrong? Is it even possible to install OpenCL on Windows Linux Subsystem?
Note:
I'm using an AMD R9 390X from MSI, 64bit Windows Home Edition
With the launch of WSL2, CUDA programs are now supported in WSL (more information here), however there is still no support for OpenCL as of this writing: https://github.com/microsoft/WSL/issues/6951.
According to a Microsoft representative in this forum post, Windows Subsystem for Linux does not support OpenCL or CUDA GPU programs, and support is not currently planned. To experiment with TensorFlow/OpenCL it would probably be easiest to install Linux in a dual-boot configuration.
You could use the Intel OpenCL SDK for the CPU, https://software.intel.com/en-us/articles/opencl-drivers.
The reason i am interested is that there is an everlasting problem with linux and proprietary drivers. Why hardware vendors do not ship their drivers in LLVM IR form?
You can write Linux device drivers in user mode code. I have seen demonstrations written in Python (handy for prototyping).
Presumably your idea is that hardware vendors could ship a LLVM IR driver, and then the driver would work with x86, ARM, or anything else? Most hardware vendors are not interested in niche-markets, and only want to support their hardware on particular platforms that they have tested on.
There is very rarely any interesting IPR in a driver (although there may well be in the library on top of the driver). If vendors wanted to support multiple platforms, they could just ship C code with instructions to build, and a restrictive (or even GPL) license.
Using VMware 10 and ubuntu 13.10 as the guest OS.
Installing the guest additions can provide hardware rendering for OpenGL 2.1
For academic purposes, there is a need to develop and run OpenGL 3+ code, preferably in the virtual machine.
I assume that it is not possible to use the host GPU, so I am trying to force software rendering, using an OpenGL 3+ renderer.
Mesa3D + llvmpipe seems promising, but I am unable to find information on whether the software renderer supports OpenGL 3+.
Is there a way to develop OpenGL 3+ under vmware?
EDIT: (For someone who replied and then deleted their post :p)
Yes, I am also seeing OpenGL 2.1 using glxinfo. I removed hardware acceleration in my VM, and am only interested in software rasterization, even if it is really slow. The question is, is there a version of llvmpipe that implements a software rasterizer for OpenGL versions higher than 2.1? I know that mesa3d supports it, albeit only for hardware.
The mesa software renderer (both the "old" pre-gallium swrast and the "new" gallium softpipe/llvmpipe), do support most of GL3.2. The only major thing missing is support for multisampling, hence they are not advertising full 3.0 support.
Update 2017
Current versions of mesa's various software rasterizers now do claim to support up to GL 3.3 in a core profile. (The progress can be tracked on https://mesamatrix.net/). However, there is a caveat, as documented in mesa's feature.txt:
freedreno, llvmpipe, softpipe, and swr have fake Multisample anti-aliasing support
which means they still do not fullfill the requirements of the GL 3.0 spec. However, in most cases, this will not matter in practice. But one should still be aware of that limitiation.
In case anyone is still interested, VMWare Workstation (both Workstation Pro and Workstation Player) have added OpenGL 3.3 support in version 12.
However, at the time of writing, the Linux guest drivers side of the equation has not been available, and is planned for Linux 4.3.
So: Use VMWare Workstation Player (or Pro, if you have it) version 12 or up, and Linux 4.3 or up.
Update: using VirtualBox without any kind of acceleration and Mesa LLVMpipe, I also get OpenGL 3.3 support (Mesa version is 17.1.1)
I have a very simple Toshiba Laptop with i3 processor. Also, I do not have any expensive graphics card. In the display settings, I see Intel(HD) Graphics as display adapter. I am planning to learn some cuda programming. But, I am not sure, if I can do that on my laptop as it does not have any nvidia's cuda enabled GPU.
In fact, I doubt, if I even have a GPU o_o
So, I would appreciate if someone can tell me if I can do CUDA programming with the current configuration and if possible also let me know what does Intel(HD) Graphics mean?
At the present time, Intel graphics chips do not support CUDA. It is possible that, in the nearest future, these chips will support OpenCL (which is a standard that is very similar to CUDA), but this is not guaranteed and their current drivers do not support OpenCL either. (There is an Intel OpenCL SDK available, but, at the present time, it does not give you access to the GPU.)
Newest Intel processors (Sandy Bridge) have a GPU integrated into the CPU core. Your processor may be a previous-generation version, in which case "Intel(HD) graphics" is an independent chip.
Portland group have a commercial product called CUDA x86, it is hybrid compiler which creates CUDA C/ C++ code which can either run on GPU or use SIMD on CPU, this is done fully automated without any intervention for the developer. Hope this helps.

If you're interested in learning a language which supports massive parallelism better go for OpenCL since you don't have an NVIDIA GPU. You can run OpenCL on Intel CPUs, but at best you can learn to program SIMDs.
Optimization on CPU and GPU are different. I really don't think you can use Intel card for GPGPU.
Intel HD Graphics is usually the on-CPU graphics chip in newer Core i3/i5/i7 processors.
As far as I know it doesn't support CUDA (which is a proprietary NVidia technology), but OpenCL is supported by NVidia, ATi and Intel.
in 2020 ZLUDA was created which provides CUDA API for Intel GPUs. It is not production ready yet though.
