Many of MIOpen kernels have parameters which affect their performance. Setting these parameters to optimal values allows reaching the best possible throughput. These optimal values depend on many things, including network configuration, GPU type, clock frequencies, ROCm version etc. Because of these dependencies and also due to enormous number of possible network configurations, it is virtually impossible to supply all values that users may need together with the library.
Instead, MIOpen provides a set of pre-tuned values for the most applicable network configurations, and also means for expanding the set of optimized values.
MIOpen's performance database contains these pre-tuned parameter values as well as optimized parameters tuned by users. MIOpen also has auto-tuning functionality, which is able to find optimized kernel parameter values for a specific configuration.Blat egger
The auto-tune process may take a substantial amount of time, however, once the optimized values are found, they are stored in the User PerfDb. MIOpen then will automatically read and use these parameter values when needed again instead of running the expensive auto-tuning search. See Setting up locations for more information. During the call, auto-tuning is performed only for one problem configuration implicitly defined by the tensor descriptors passed to API function.
The latter two conditions may be overridden by enforcing the search by means of the following environment variables:. Setting the value to "NONE", or "1" will have no change in the default behavior. Auto-tune will not be skipped even if PerfDb already contains optimized values. This mode can be used for fine-tuning the MIOpen installation on the user's system. When MIOpen is in this mode, the applications that use it may take quite long to finish.
In other words, the library will behave as if exhaustiveSearch parameter set to true even this is not really so. If optimized values already reside in PerfDb, then auto-tune will not be performed. This mode allows for tuning the apps that do not anticipate means for getting the best performance from MIOpen. When MIOpen is in this mode, the first run of the user's app may take substantially longer time than expected.
It is not recommended to use this mode except for debugging purposes. Use with care. Auto-tune is blocked, even if it is explicitly requested. System PerfDb left intact. Both symbolic case-insensitive and numeric values are supported, as shown below. This is the default. WRW convolutions. It is important to note that if the user installs a new version of MIOpen, it is recommended that the user move, or delete their old user performance database file.
This will prevent older database entries from poluting the configurations shipped with the newer system database. The user perf db is named miopen. MIOpen 2. The performance database consists of two parts: System Performance Databasea system-wide storage which holds the pre-tuned values for the most applicable configurations, User Performance Databasea per-user storage which is intended to hold optimized values for arbitrary configurations.
Auto-tuning the kernels.

The following conditions must be met for the auto-tune to begin: The applicable kernel s has tuning parameters.
The passed value of exhaustiveSearch parameter is trueand Both System and User PerfDb do not yet contain values for the relevant problem configuration.Advanced Micro Devices Inc. The three-year-old library contains more than 3, software routines that focus on specific functions, such as handling audio and video data, according to Margaret Lewis, director of commercial solutions at AMD. This is the first time that AMD has released a proprietary library set and released it as open source.
Since the routines are focused on x86 machines, that means they should work for both AMD-based and Intel-based systems. Multimedia workloads will particularly benefit as they can be extremely power hungry in terms of processing cycles.
Moving this code to open source makes it easy for developers. It might also help them win more developer fans — developers who say that their products work on both AMD and Intel, but might perform better on AMD processors. Skip to content. CDN is produced by.

This is the first time that AMD has released a proprietary library set and released it as open source. We've spent a lot of time tuning [these routines] so the code runs faster and the developer doesn't have to write the routine and then optimize it himself. It's immediately available for download at this site. Since the routines are focused on x86 machines, that means they should work for both AMD-based and Intel-based systems.

It isalso quite technical question. We can't guarantee the performance benefits of code which was tightly optimized for Intel architecture when it will run on other architecture.
And of course, we do not guaranteethe compatibility of third party processors with Intel architecture. Using generic code is more safe.Radeon Boost Analysis: A Free Performance Boost For AMD Graphics Cards?
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 closedespite all its "safety".
Let us be honest, "generic"performance library makes no sense whatsoever Isit documented somewhere? Yes, IPP does contain optimized code for Intel micro architecture. It means exactly what it is - for Intel microarchitecture, not for others. One note about the "right" DLL. Not only instruction set is taken into account here. The other features of architecture is also important, like cache features, branch prediction features and so on.
It's the PX code that should be dispatched on all non-Intel processor-based systems. 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.
Since you have complete control on this DLL you can write your own functions to select the best optimizations W7, T7, A6, PX depending on cpuid or configuration file. You can load them. Also, you can plug your own implementations.
My practice shows that it's not impossible to beat IPP. You will probably need a small script that parses IPP headers and creates all-inclusive header file and export. The resulting library will be a bit bulky around 40MB in my case but you will have a benefit of worrying about just a single file. I prefer to work with DLL rather than with static lib because of better compatibility among other reasons.
Thanks for your help. The point is that I also have size constraints, i. Of course I have to declare and export them but Do you think it will work?
Why not? You can even tweak custom DLL to export all possible functions: 1.They have a simple interface to take advantage of the latest hardware innovations.
The tuned implementations of industry standard math libraries enable fast development of scientific and high-performance computing projects. For any issues or queries regarding the libraries, please contact toolchainsupport amd. The framework was designed to isolate essential kernels of computation that, when optimized, immediately enable optimized implementations of most of its commonly used and computationally intensive operations.
It is an open-source implementation of the Fast Fourier transform algorithm. It can compute transforms of real and complex-values arrays of arbitrary size and dimension.
AMD LibM is a software library containing a collection of basic math functions optimized for x processor-based machines. It provides many routines from the list of standard C99 math functions. The library provides scientific and numerical computing communities with a modern, high-performance dense linear algebra library that is extensible, easy to use, and available under an open source license.
It provides a comprehensive set of statistical distribution functions and various uniform distribution generators base generators including Wichmann-Hill and Mersenne Twister. The library contains five base generators and twenty-three distribution generators, in addition to hooks for user provided base generator.
