For Linux, the NUMA platforms of interest are primarily what is known as Cache Coherent NUMA or ccNUMA systems. With ccNUMA systems, all memory is visible to and accessible from any CPU attached to any cell and cache coherency is handled in hardware by the processor caches and/or the syste...
In NUMA systems, memory is not a shared, uniform resource but is segmented and allocated to specific nodes. Each node’s memory serves as the primary storage for the processors within that node. By localizing memory resources, the system reduces the operational overhead associated with a single,...
Scheduler worker migrationWorker migration allows an idle scheduler to migrate a worker from the runnable queue of another scheduler on the same NUMA node and immediately resume the task of the migrated worker. This enhancement provides more balanced CPU usage in situations where long-running tasks ...
Today, with the practical use of the Linux operating system in a wide range of activities on desktops and servers, users have become more interested in learning about Linux distributions. You know that Linux, with its powerful infrastructure, is used for any purpose and activity and has the be...
Because of its small image size, Alpine Linux is widely adopted in cloud deployments, microservices, and container environments. A Docker picture is smaller than 6 MB for Linux. In such environments, letting Java run out-of-the-box will allow Tomcat, Jetty, Spring, and other common frameworks...
What is CC NUMA - CC-NUMA stands for Cache-coherent non-uniform memory access machines. A CC-NUMA machine includes several processing nodes linked through a high-bandwidth low-latency interconnection network. Each processing node includes a high-implemen
Beginning with MySQL 8.4.0, the deprecated mysql_native_password authentication plugin is no longer enabled by default. To enable it, start the server with --mysql-native-password=ON (added in MySQL 8.4.0), or by including mysql_native_password=ON in the [mysqld] section of your MySQL co...

Optimizing workloads with cgroup v2 and NUMA controls Control groups (cgroups) are part of the Linux kernel that help container runtimes isolate processes so they are contained. In addition to Linux containers, cgroups are useful for other services and applications running on RHEL. ...
