英特尔® 资源调配技术 (英特尔® rdt) 框架. 英特尔® rdt 提供了一个由多个组件功能（包括 cmt、cat、cdp、mbm 和 mba）组成的框架，用于缓存和内存监控及分配功能。

Oct 2, 2020 · MBA can be also configured using rdtset utility instead of pqos. rdtset is a taskset-like application that provides easy to use interface for running applications and configuring RDT for them. Once the application is no longer running, rdtset …

Mar 12, 2019 · The Intel® Xeon® Scalable processors introduce Memory Bandwidth Allocation (MBA), which provides new levels of control over how memory bandwidth is distributed across running applications. MBA enables improved prioritization, bandwidth management and is a valuable tool to help control data center noisy neighbors.

Intel® RDT provides a framework with several component features for cache and memory monitoring and allocation capabilities, including CMT, CAT, CDP, MBM, and MBA. These technologies enable tracking and control of shared resources, such as the Last Level Cache (LLC) and main memory (DRAM) bandwidth, in use by many applications, containers or ...

Mar 25, 2019 · With an Intel RDT enabled system, a system administrator or orchestrator can monitor and allocate memory bandwidth or Last Level Cache (LLC), per application, container, virtual machine (VM), or even per-thread if necessary.

Jan 18, 2024 · 内核中通过 resctrl 文件系统 提供以上能力，4.10 中实现了 L3 CAT、L3 CDP、L2 CAT，4.12 进一步支持了 MBA。 本文主旨在于解析内核 resctrl 文件系统（RDT 框架）对 RDT 底层硬件的抽象及实现。 2. 垫话. 某平台组织过一次关于 PMU 主题的公开课，我对此话题感兴趣的本意是希望能了解内核对 PMU 框架 的抽象及实现（perf_event）。 但当我提出相关问题时，大佬表示看不懂我的问题并直接 pass 了。 一两个小时听下来，记住的信息只有两条：“人类是愚 …

英特尔® 资源控制器技术 (RDT：Resource Director Technology) 提供了一组资源分配（或控制）功能，可控制应用程序如何使用共享资源，例如末级缓存 (LLC) 和内存带宽。RDT 包括缓存分配技术 (CAT：Cache Allocation Technology) 和内存带宽分配 …

Oct 7, 2023 · RDT技术全称 Resource Director Technology，RDT技术提供了LLC（Last Level Cache）以及MB（Memory Bandwidth）内存带宽的分配和监控能力。 RDT的主要功能有以下几个： 在混合部署场景下，cgroup提供了粗粒度的CPU、内存、IO等资源的隔离和分配，但是从软件层面无法对LLC和内存带宽等共享资源进行隔离，离线业务可以通过争抢LLC和内存带宽来干扰在线业务。 RDT从硬件层面提供了细粒度的LLC资源的分配和监控能力，在混部场景运用广泛。

Nov 16, 2022 · Individual Intel(R) RDT features can be enabled/disabled by passing kernel command line parameters at boot. For example, to turn on CMT and turn off MBA, add the following to your kernel command line: rdt=cmt,!mba. The full list of parameters is: cmt, mbmtotal, mbmlocal, l3cat, l3cdp, l2cat, l2cdp, mba.
