Non-uniform memory access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory (memory local to another processor or memory shared between processors). [ 1 ]
learn.microsoft.com /en-us /windows-hardware /test /hlk / The Windows Hardware Lab Kit ( Windows HLK ) is a test automation framework provided by Microsoft to certify devices for Windows. Earlier similarly released frameworks were called Windows Hardware Certification Kit (Windows HCK) and Windows Logo Kit (WLK).
Typically multiple examinations were required to obtain either a hardware centered certification such as the MCSE (Microsoft Certified Systems Engineer) or a more software orientated offering such as the MCSD (Microsoft Certified Solutions Developer). The process of earning certification has changed multiple times since its initial inception.
Directory-based coherence is a mechanism to handle cache coherence problem in distributed shared memory (DSM) a.k.a. non-uniform memory access (NUMA). Another popular way is to use a special type of computer bus between all the nodes as a "shared bus" (a.k.a. system bus). [1]
Modern desktop and server CPUs integrate the EDAC circuit into the CPU, [22] even before the shift toward CPU-integrated memory controllers, which are related to the NUMA architecture. CPU integration enables a zero-penalty EDAC system during error-free operation.
Certified for Vista Logo Warning for uncertified hardware drivers on Windows XP The "Found New Hardware Wizard" of Windows XP. Products that pass the WHQL tests get to use a "Certified for Windows" logo, which certifies that the hardware or software has had some share of testing by Microsoft to ensure compatibility.
Includes enhanced support for Non-Uniform Memory Access (NUMA) and systems with large memory pages. Windows Vista also exposes APIs for accessing the NUMA features. Memory pages can be marked as read-only, to prevent data corruption. New address mapping scheme called Rotate Virtual Address Descriptors (VAD). It is used for the advanced Video ...
Uniform memory access (UMA) is a shared memory architecture used in parallel computers.All the processors in the UMA model share the physical memory uniformly. In an UMA architecture, access time to a memory location is independent of which processor makes the request or which memory chip contains the transferred data.
