In DragonFly BSD 3.1 (2012) and later, usched utility can be used for assigning processes to a certain CPU set. [10] On Windows NT and its successors, thread and process CPU affinities can be set separately by using SetThreadAffinityMask [11] and SetProcessAffinityMask [12] API calls or via the Task Manager interface (for process affinity only).
CMake generates configuration files for other build tools based on CMake-specific configuration files. The other tools are responsible for more directly building; using the generated files. A single set of CMake-specific configuration files can be used to build a codebase using the native build tools of multiple platforms. [4]
AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly. [2]
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
AMD K7 Athlon – microarchitecture of the AMD Athlon classic and Athlon XP microprocessors. Was a very advanced design for its day. First generation was built with a separate L2-cache chip on a board inserted into a slot and introduced extended MMX. The second generation returned to the traditional socket form factor with fully integrated L2 ...
Set-associative cache is a trade-off between direct-mapped cache and fully associative cache. A set-associative cache can be imagined as a n × m matrix. The cache is divided into ‘n’ sets and each set contains ‘m’ cache lines. A memory block is first mapped onto a set and then placed into any cache line of the set.
Zen 3 with 3D V-Cache was officially previewed on May 31, 2021. [33] It differs from Zen 3 in that it includes 3D-stacked L3 cache on top of the normal L3 cache in the CCD, providing a total of 96 MB. The first product that uses it, the Ryzen 7 5800X3D, was released on April 20, 2022. The added cache brings an approximately 15% performance ...
The Infinity Cache is made up of two sets of 64 MB cache that can run on its own clock rate independent from the GPU cores. The Infinity Cache has a peak internal transfer bandwidth of 1986.6 GB/s and results in less reliance being placed on the GPU's GDDR6 memory controllers. [8] Each Shader Engine now has two sets of L1 caches.
