relocatable
- type:
- boolean
- example:
- config relocatable : false;
- description:
- The operator instance can be relocated on a different host. For example, after a failure or for better load balancing that is based on relocation recommendations from the scheduler. The relocatable config implies the restartable config. Furthermore, if an operator A is relocatable and operator B is not, then A and B are partition-exlocated (cannot be in the same partition), unless the compiler option -O, --setRelaxFusionRelocatabilityRestartability is used. Remember from the language specification that a local config overrides a global config; similarly, a local inferred config overrides a global config even if that global config is explicit.
- default:
- true
- where:
- Any operator invocation or composite
operator. Tip: You can set config relocatable on a main composite to make all enclosed PEs relocatable.
