Tuned
The roller can be applied with osism apply tuned. The role is applied to all
compute nodes by default. This can be changed via the hosts_tuned parameter.
The profile to be used can be set via tuned_profile. By default, virtual-host
is used.
The following profiles are available:
| Profile | Description |
|---|---|
| accelerator-performance | Throughput performance based tuning with disabled higher latency STOP states |
| atomic-guest | Optimize virtual guests based on the Atomic variant |
| atomic-host | Optimize bare metal systems running the Atomic variant |
| balanced | General non-specialized tuned profile |
| cpu-partitioning | Optimize for CPU partitioning |
| default | Legacy default tuned profile |
| desktop | Optimize for the desktop use-case |
| desktop-powersave | Optmize for the desktop use-case with power saving |
| enterprise-storage | Legacy profile for RHEL6, for RHEL7, please use throughput-performance profile |
| hpc-compute | Optimize for HPC compute workloads |
| intel-sst | Configure for Intel Speed Select Base Frequency |
| laptop-ac-powersave | Optimize for laptop with power savings |
| laptop-battery-powersave | Optimize laptop profile with more aggressive power saving |
| latency-performance | Optimize for deterministic performance at the cost of increased power consumption |
| mssql | Optimize for MS SQL Server |
| network-latency | Optimize for deterministic performance at the cost of increased power consumption, focused on low latency network performance |
