Colocated infrastructure with MPMD application
Description
In SmartSim, MPMD applications cannot be colocated with an Orchestrator
. An error will be thrown if the RunSettings
associated with the application has been converted to an MPMD application (https://github.com/CrayLabs/SmartSim/blob/fbcc46afe3608a8316f83520217a5856f29d5167/smartsim/entity/model.py#L343). However, users with MPMD applications should be able to launch the colocated Orchestrator.
Justification
This issue was reported by a user constructing online inference workflows with an MPMD application.
