It isalso quite technical question. I remember that older version of IPL detected AMD Athlon as Pentium III and used PIII optimizations. Thanks for your help. That seems like the only responsible thing to do, rather than trusting strangers on the internet ;) Apart from that, I believe part of AMD's lawsuit against Intel is based on the claim that Intel's compiler specifically produces code that runs inefficiently on AMD processors. Doyou have any plans to support Opteron and AMD64 architecture natively? It's the PX code that should be dispatched on all non-Intel processor-based systems. Overview. The second problem is that buyers of AMD products demand that Intel would release their software optimized for AMD products as well, which is just nonsensical. Thanks for all your tricks. As a matter of fact, IPL version 3.0 with Pentium III optimizations is running perfectly on my Athlon. The article indicates a fair handling of non-Intel processors in the IPP library. Overall speed isnotworse than on a comparable Pentium III.Based onthis practical experience, it is hard toacceptswitching to PX. Core math functions include BLAS, LAPACK, ScaLAPACK, sparse solvers, fast Fourier transforms, and vector math.. I see, I have to repeat it again. 2.8K views View 24 Upvoters What favor is to be used for AMD processors? I tried everything and it's working fine, even if I'm not that satisfied with that method (calling IPP's that way is fully unsupported, I suppose !). The Intel vs AMD rivalry isn’t exclusive to the desktop space, as it also continues over to the laptop market. Using generic code is more safe. Yes, IPP does contain optimized code for Intel micro architecture. So you don't have to rewrite or recompile anything if you are using it on AMD system. I sent this question to AMD tech support's "CPU … If yourcpu don't support SSE2, thenthe general otpimzed code for all IA32-processors will be used. Yes, as shyaki said, the current AMD processor areat least support SSE2 and support same intruction set as Intel Processor, soIPP will use at least "w7" codeon such kind of cpus. YES, other features such as cache properties, branch prediction etccan be important. OpenCV can be compiled statically with IPP libraries from Intel also which can speed up some function. Message Edited by ZXS on 06-04-2004 04:41 PM. The library supports Intel processors and is available for Windows, Linux and macOS operating systems. OpenCV is well-optimized for Intel platforms, in particular: A […] Becausethe answermay depend on the things not known at compile time likepatterns of input, CPU load (other apps running in background and polluting cache), L2 cache size, type and speed of main RAM,etc. By the way, thank you very much for having taking time answering to me, that's great . In processor market, Intel is the most famous, but AMD processors are also at a level that provides a tight competition for Intel. My CPU is Athlon 64. Historically IPP works on AMD chips as most AMD chips is Intel compatible. you can't call Advapi's Registry functions - quite disappointing, isn't it?). It means exactly what it is - for Intel microarchitecture, not for others. Let us be honest, very fast program doing wrong calculations makes no sense for anyone. AMD and Intel are both American Companies where they manufacture silicon-based products such as processors, chipsets, etc. My work pc is an AMD Phenom X4, 3.8GHz. manufacturers supporting the same instruction set. Guys, you are doing great job with IPP library.The only doubt I have is the futuresupport for AMD processors. These functions (ippStaticInit, ippStaticInitCpu, ippStaticFree) do nothing when they called from DLLs. Intel’s products and software are intended only to be used in applications that do not cause or contribute to a violation of an internationally recognized human right. This is in accordance with my test results. Because Intel has dominant position on CPU market, other vendors do mimic behaviour of Intel CPUs for software compatibility (though internal design of"other" CPUs can be quite different) - so machine code optimized for Intel CPUsis also pretty efficient on other processors. Unfortunately, software compiled with the Intel compiler or the Intelfunction libraries has inferior performance on AMD and VIA processors. The other features of architecture is also important, like cache features, branch prediction features and so on. AMD has this problem when competing against nvidia in the GPU space, and against intel in the CPU space. For more complete information about compiler optimizations, see our Optimization Notice. IPP only works on desktop processors. However, they are reported to be slower on AMDs). We do very thin optimization for Intel architecture, and we can't guarantee any resultsfor this optimized codeon other architecture. Certain DSP type workloads seem to show very significant performance improvement on Intel x86 x86_64 processors, when linked against Intel IPP library. But, at least, if some third party CPU supports compatible SIMD instruction set (MMX,SSE,SSE2,SSE3)then it isreasonable to load"right'DLLs i.e. Yes, "generic" code can't provide you the best performance and it was not dedicated for that. Of course I have to declare and export them but Do you think it will work ? One thing I forgot to mention. Hello, I am trying to use IPP to compute dot product of two 16-bit integer vectors. Guys, you are doing great job with IPP library.The only doubt I have is the futuresupport for AMD processors. Intel Math Kernel Library (Intel MKL) is a library of optimized math routines for science, engineering, and financial applications. Let us be honest, "generic"performance library makes no sense whatsoever... Howdoes IPP libraryselect a version of optimizations (PX,A6,W7,T7) to be loaded? BTW, it would be interesting to take a look atthe non kosher MMX instruction producing wrong resultson Athlon. It would be hard to expect that IPP supported all existing CPU microarchitectures. Intel IPP doesn't support GPUs. I discovered that IPP function ippsDotProd_16s64s does not use SSE[1,2,3] instructions if 64-bit version is used, while32-bit version does employ SSE3 ones. Isit documented somewhere? There are other architectures, but they're niche, and you would probably know if you had a CPU with one of those niche architectures because you would have bought the CPU with a particular goal in mind. 1. Intel integrated graphics is supported only by OpenCL. Intel IPP library (when linked with OpenCV) will provide some speedup due to intensive use of SIMD instruction set. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Its royalty-free APIs help developers: Take advantage of Single Instruction Multiple Data (SIMD) instructions It was kind of "preview" product - Intel 8.0 Preview, which was discontinued. It provides you working solution whichgives the same results in terms of accuracy on other than Intel but 100% compatible architecture. Thanks for the replies, its all clear now. The library supports Intel and compatible processors and is available for Linux, macOS, Windows and Android operating systems.It is available separately or as a part of Intel Parallel Studio. As a workaround, currently one can get away with forcing PIII optimizations on Athlon. For non-Intel based processors support, please see the article titled Use Intel® IPP on Intel or Compatible AMD* Processors. Most CPUs that people buy for workstations, gaming PCs, etc., use amd64 architecture. IPP doesn't disable any optimizations for AMD CPUs - IPP dispatching mechanism is based on features supported by current CPU, so as Phenom II supports SSE2 and SSE3 - w7 code should be dispatched for ia32 mode and m7 for x64. Many software programmers consider Intel's compiler the best optimizingcompiler on the market, and it is often the preferred compiler for the mostcritical applications. There are certain limitations on functions to be called inside DLL intialisation routine (e.g. (like, instead of calling ippiCopyBlock_H263_8u, calling a6_ippiCopyBlock_H263_8u or something like that ?). Intel IPP is … One note about the "right" DLL.In IPP"right" DLL is DLL which was designed forappropriate processor.Not only instruction set is taken into account here. It is like this. We have "generic" code, which should work on 100% compatible architecture. Thereason … P8/Y8 Internal Run-Time Dispatcher Within the 32-bit 'p8' and equivalent 64-bit 'y8' architectures there is an additional "run-time" dispatching mechanism, a kind of mini-dispatcher. OpenCV project has been started at Intel back in 1998, with the first public release in 2000. The compilers generate optimized code for IA-32 and Intel 64 architectures, and non-optimized code for non-Intel but compatible processors, such as certain AMD processors. Hi, we are developing an image/signal processing application that need to work without a processor-brand constraint. Although, the latest Intel 2-nd generation Core 2 processors have an additional 256-bit AVX instructions (not available yet on AMD). Difference between AMD and Intel products are observable in their performance and features. OpenCV and Intel have a long history of fruitful collaboration. Intel Integrated Performance Primitives (Intel IPP) is a multi-threaded software library of functions for multimedia and data processing applications, produced by Intel.. I develop an IPP custom dll with a subset of IPP, enabling OpenMP, compiled with Intel C++ 10.2. We are glad to have pleasant feedback:). But usually they are less important than ability to process several values at once (SIMD).I believe that impact of differences in these featuresis not so critical. is there a strict constraint to use Intel C++ compiler for optimized solution? What about AMD processors support, it is not only political question. Yes, both AMD and Intel processors fully implement the IA-32 and x86–64 instruction sets, and can execute the same software. AMD's own stats, shown above, suggest this is the direction it deliberately opted to take: prioritize operating time over performance. DLLs designed for this instruction set. Inmany cases, there are no good alternatives to Intel's function libraries. The point is that I also have size constraints, i.e a dll more than a few hundreds kilobytes is not acceptable to me. These appear to be very well engineered at the lowest levels, but the packaging is a mess, as I’ll describe below. No, there is no way to dispatch "Intel cpu specific" code on non-Intel processors. Will youNOT implement "special measures" to prevent using your libraryon AMD processors? Buy an AMD box and run it on that. Among other features, the library includes: I am simply interested whether my "ready to deploy" application will run on either systems. What weguarantee"generic" code of IPP will correctlywork on processors which is 100% compatible with Intel. For more complete information about compiler optimizations, see our Optimization Notice. Lastrelease of IPP detects exactly same Athlon as a generic Pentium and basically disables all optimizations on this CPU. I'm using a machine with AMD processor for upgrading IPP 3.0 to 5.0. Is it possible toaddkeyto the Windows registry which would allow to configure IPP to load the user-selected version of the library, or tosetitto AUTO-DETECT(by default)? Last week, Apple launched its M1 SoC. My specific immediate question is whether the AMD Opteron 2218 HE processor supports Intel Integrated Performance Primitives (IPP libraries), version 5.3. And of course, we do not guaranteethe compatibility of third party processors with Intel architecture. Yes, you can, but we do not provide support for such using of IPP on non-Intel processors. Even now, 20 years later, Intel Corporation still funds the core OpenCV development team and maintains the build farm. We can't guarantee the performance benefits of code which was tightly optimized for Intel architecture when it will run on other architecture. Hello,you may check with IPP Release Notes for supported software. Intel IPP Cryptography is an add-on library that offers Intel IPP users a cross-platform and cross operating system application programming interface (API) for routines commonly used for cryptographic operations. Likewise, Intel is supplying a lot of highly optimizedfunction libraries for many different technical and scientific applications. For more info, see MSDN on DLL_PROCESS_ATTACH. // Intel is committed to respecting human rights and avoiding complicity in human rights abuses. OpenCV is poorly optimized on mobile devices, which use ARM processors, and for now, the best option seems to be the Accelerate framework offered by iOS 4.0 and higher. Of course, the code dispatching is doingwithanother algorithm. See Intel’s Global Human Rights Principles . > The point is that I also have size constraints. Install CD contains multiple flavors of installs, based on processor type. You can live without it if you still have first order optimization i.e. Wondering if there is something similar on ARM side ? SIMD.Also it is really hard to make sure that such fine grained optimizationsare doingmore good thanharm. It is like second order optmization. What if the instruction set is different? Though these companies produce different other products as well, in this article, we mai… I remember that older version of IPL detected AMD Athlon as Pentium III and used PIII optimizations. Could you be more specific and provide an output from ippGetLibVersion … Message Edited by ZXS on 05-12-2004 08:12 PM, Message Edited by ZXS on 05-12-2004 08:13 PM, thank you for high valuation of IPP libraries. On the other hand, OpenCV can sometimes run much faster on Intel processors (and sometimes AMD) because it can take advantage of SSE optimizations. This gives me a small … In 2010, Intel published an article on how the CPU dispatching works in the Intel Performance Primitives (IPP) function library. I can recommend the following workaround. I'd like to get this info for some other processors as well. The performance benefit from using SIMD instruction set avialble on both Intel and AMD systems. Or do we develop the code with IPP support but it won't work optimized if it detects a non-Intel cpu ? It works fine for me... WillI be able to use IPP on AMD processors? Yes, Microsoft compiler can be used with IPP as well as gcc under Linux and Mac OS. How come AMD Phenom II X4 965 Black Edition (4 cores @ 3.4 GHZ) or AMD Phenom II X6 1075T (6 core @ 3.0 GHz) is not sufficient to run PS 2021, while Intel Core i3-2310M (2 core @ 2.1GHz) is considered enough? Or can we compile our IPP codes with any other c-c++ compiler such as MSVC? It needs to run on Intel as well as on AMD processors. I guess that there is a generic version of our IPP code, if the detected cpu is non-Intel, the generic code works. I hope it is not something like this: IFCPUID()= "AuthenticAMD" THENpx(). Modern AMD and Intel CPUs all support the amd64 architecture. Built around the same A14 CPU as the latest iPhone, the M1 is the first non-x86 CPU architecture to challenge companies like AMD and Intel … As Vladimir replied early, the Intel IPP will run on processors that are 100% compatible with Intel Architecture. If a build my own custom dll (that's what I'm doing for the moment), can I call directly targeted functions for PIII or PIV ? Generic code was developed for processors which 100% compatible with Intel architecture. Following are the directoreis I see in the install CD. Hi, I am working on an application that uses the FFT of IPP. Intel vs AMD – Laptop processors. Intel Integrated Performance Primitives Bewilderment I’ve been evaluating Intel’s Integrated Performance Primitives , a set of libraries for low-level signal processing and image manipulation. "Generic" code has no SIMD optimizations.Such codecannot be used as a foundation of cometitive high-perfomance application because it does not take full advantage of available capabilities of modern CPU (not even close), despite all its "safety". Lastrelease of IPP detects exactly same Athlon as a … Should we develop different codes, namely the generic and IPP? (Intel and AMD, x86/64 architectures. So, a generic version of our IPP code is generated automatically by Intel compiler, is it that ? Intel® Integrated Performance Primitives (Intel® IPP) is an extensive library of ready-to-use, domain-specific functions that are highly optimized for diverse Intel® architectures. Looking at some older posts, there is a term called "generic code". I know you don't provide any support when linking statically and "forcing" a processor type using ippStaticInitCpu, but I would like to know if it's possible to do so while linking dynamically ... No, there is no way to force cpu-specific code using for DLLs. Depending on the speed of the CPU, one may execute software more quickly than the other, but both will work. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Q2. Especially that might work accross ARM9, ARM11 and Cortex-A8/A9's (not necessarily with the same level of performance boost). I am not asking for an optimized performance.
