Name
migration_factor — Multiply or divide the migration costs.
Synopsis
migration_factor=
percent
Modify the default migration costs by the specified
percentage
. This is a debugging option
that can be used to proportionally increase or decrease the
auto-detected migration costs for all entries of the migration
matrix. For example, migration_factor=150
increases migration
costs by 50%, so the scheduler will be less eager to migrate
cache-hot tasks. migration_factor=80
decreases migration
costs by 20%, thus making the scheduler will be more eager to
migrate tasks.
Warning
Incorrect values can severely degrade scheduler performance, so this option should be used only for scheduler development, never for production environments.
