The openSUSE Slowroll distribution is a middle-ground between the rolling-release openSUSE Tumbleweed Linux distribution and the SUSE Linux Enterprise aligned openSUSE Leap with its fixed releases. The new openSUSE Slowroll is a rolling-release-like distribution with updates “every one or two months” but with constant bug/security fixes…

Sub-NUMA Clustering with Intel Xeon processors allows for splitting up the CPU cores, cache, and memory into multiple NUMA domains for enhancing the performance of NUMA-aware applications. While SNC can help in a number of cases especially plenty of HPC and server workloads, currently it’s not properly supported if making use of Resource Director Technology (RDT) on modern Intel CPUs. That is in the process of changing with new Linux kernel patches being worked on by Intel…
