OLA Thread Scheduling
From wiki.openlighting.org
Since 0.9.4, OLA provides options to control the thread scheduling algorithms, when supported by the host kernel.
Besides the default scheduling policy (SCHED_OTHER), OLA supports SCHED_RR and SCHED_FIFO. You can read about the differences on The Linux Journal.
Configuration
If you're on Linux you need to edit /etc/security/limits.conf and add:
<username> hard rtprio 99 <username> soft rtprio 50
Replace <username> with the user you run olad as.
Running OLA
Start olad with --scheduler-policy and --scheduler-priority. You must provide both flags.
$ olad --scheduler-policy fifo --scheduler-priority 10
The --scheduler-priority flag must be a value less than or equal to the soft rtprio limit set in /etc/security/limits.conf.
