Name
migration_factor — Multiply or divide the migration costs.
Synopsis
migration_factor=
percent
Description
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.
