Skymont in Gaming Workloads

E-Cores are central in Intel’s CPU strategy. Their small area footprint helps Intel achieve high multithreaded performance in a low area footprint. But E-Cores don’t derive their strength from numbers alone, because they still have significant per-core performance.…

Predictable memory accesses are much faster

Loading data from memory often takes several nanoseconds. While the processor waits for the data, it may be forced to wait without performing useful work. Hardware prefetchers in modern processors anticipate memory accesses by loading data into the cache…

Arch Linux: Recent news updates
zabbix >= 7.4.1-2 may require manual intervention

Starting with 7.4.1-2, the following Zabbix system user accounts (previously shipped by their related packages) will no longer be used. Instead, all Zabbix components will now rely on a shared zabbix user account (as originally intended by upstream and done by other distributions):

● zabbix-server
● zabbix-proxy
● zabbix-agent (also used by the zabbix-agent2 package)
● zabbix-web-service

This shared zabbix user account is provided by the newly introduced zabbix-common split package, which is now a dependency for all relevant zabbix-* packages.

The switch to the new user account is handled automatically for the corresponding main configuration files and systemd service units.

However, manual intervention may be required if you created custom files or configurations referencing to and / or being owned by the above deprecated users accounts, for example:

● PSK files used for encrypted communication
● Custom scripts for metrics collections or report generations
● sudoers rules for metrics requiring elevated privileges to be collected
● ...

Those should therefore be updated to refer to and / or be owned by the new zabbix user account, otherwise some services or user parameters may fail to work properly, or not at all.

Once migrated, you may remove the obsolete user accounts from your system.

Running Gaming Workloads through AMD’s Zen 5

Zen 5 is AMD’s newest core architecture. Compared to Zen 4, Zen 5 brings more reordering capacity, a reorganized execution engine, and numerous enhancements throughout its pipeline. In short, Zen 5 is wider and deeper than Zen 4. Like Lion Cove, Zen 5 delivers…
