Where could I find OpenCL SDK for intel core 2 due?
Graphic card: mobile intel (r) series express chipset family.
The current intel OpenCL SDK does not support Core 2 Duo Series CPUs. (See release notes)
If, however, you want to use that kind of CPU for OpenCL (development), you can use the AMD APP SDK. It supports all CPUs with at least SSE 2.x, as can be seen here
Works for me (Core2Duo 6750, Ubuntu)

How to check which memory consistency model does Intel i5 have? I have been searching for Macs and Intel, and it seems impossible to find. Any tips on how to search for this information?
Memory ordering rules for different Intel processors are now described in the Intel SDM, volume 3A, chapter 8, section 8.2 "Memory Ordering". There used to be an official whitepaper on the subject, now only available from non-oficial sources.
Note that information published in different revisions of the SDM from 2006 and later had been changing. An overview of what was stated by x86 memory ordering independently by Intel and AMD can be found here.
I am willing to buy a mac mini for developing IOS apps for iphones ( social networking type ) and these are my mac mini information
1.4 GHz dual-core Intel Core i5 processor
4GB memory
500GB hard drive
Intel HD Graphics 5000
OS X Yosemite
please I would like to know if this is good or not and whether I can use it for developing or not and can I use latest xcode on it ?
NOTE :: I am willing mac mini due to budget problems and I will only open xcode on it ( I will not open allot of programs together )
thanks in advance.
It should be okay for Xcode and related stuff, but the processor speed is rather low, and the regular hard drive is slow by today's standards. Also, 4GB RAM is still okay for running Yosemity or Mavericks, but the OS will need to swap or compress memory very soon. You'll probably be able to use this system for what you want, but don't expect it to be too fast, especially the HDD is considered a bottleneck.
It is very likely that you'll be able to improve the speed of that computer a lot by upgrading the HDD to an SSD and the 4GB of RAM to 8GB. Both can be done by any computer store or even by yourself.
I am new to work with Xeon Phi Co-processor and my question is:
Does exists a mechanism like CUDA streams in Xeon Phi ???
That's right, hStreams essentially covers the key features of CUDA Streams and OpenCL, in that several CUDA Streams and OpenCL apps have been ported to hStreams. Users of hStreams, like the OmpSs folks at Barcelona Supercomputing assessed that hStreams was easier to use than CUDA Streams, and offered better support for synchronization, required fewer unique APIs, and fewer lines of code.
For some more documentation, please see http://lotsofcores.com/hStreams, which you can also find a link of where to download MPSS and a blog that offers a few highlights of its features, including hStreams.
Once you've installed hStreams, look in /usr/share/doc/hStreams.
Yes. The Intel Manycore Platform Software Stack (MPSS) provides hStreams, which are designed to be similar to the CUDA streams model.
There is a chapter in High Performance Parallel Programming Pearls II on hStreams, which you can preview in Google Books.
I can't find any detailed documentation on Intel's website, but the release notes say that you can find PDFs in the MPSS distribution, which should be on any Intel Xeon Phi coprocessor system.
BSC has detailed documentation of hStreams here.
I develop an application utilizing D3D11.2 Tiled Resources feature. I have GeForce 780 and some Radeon 7900 series graphics cards, but both support only Tier 1 set.
A year ago, AMD claimed to have a hardware fully supporting Tiled Resources, but Direct3D caps reporting, that only Tier 1 can be used, determined that was a lie (probably they had some issues with conformance, performance or stability and decided to release driver with Tier 2 disabled).
I found some links to articles, that there is a chance, that Tier 2 is supported in the recently released graphics cards, like for example:
The different tier's represent the level of Tiled Resources feature supported under DX 11.2. R7 260X, R9 290 and R9 290X will have the ability to support the entire feature set, both tiers of Tiled Resources under DX 11.2 in Windows 8.1
Source: http://www.hardocp.com/article/2013/10/23/amd_radeon_r9_290x_video_card_review#.U_2OPflByjk
But IT journalist have usually no idea what they are writing about, especially when graphics hardware is concerned, so I'm asking the question here.
Is there any Radeon R7/R9 owner, who can confirm, that Tiled Resources Tier 2 is supported in these graphics cards?
Windows 8.1 SDK has tool called dxcapsviewer. You can check this in DXGI Devices -> (graphics card name) -> Direct3D 11.2 -> D3D_FEATURE_LEVEL_11_1 -> Tiled Resources.
Regards
The R9 290 does indicate support for Tiled Resources Tier 2 in the caps viewer on the latest Catalyst beta driver. It should also be enabled on the latest retail one as well. The R7 should have the same level of support.
Some time ago, I read some rumors on hardware implementation of OpenVG in Intel Atoms of a "new ganeration". Now I cannot find any evidence. So, is there at least some plans to support OpenVG at all?
The answer: Yes.
Announced Intel Atom Z6xx is a SoC (System-on-a-Chip), that includes GMA 600 graphical core. GMA 600 is able to accelerate OpenVG as well as OpenGL. I'm not sure this acceleration makes any sense, but it is supported.
