Welcome to the Maestro wiki!

Roadmap, path to 2.0+

looping on steps
looping on subgraphs (multiple steps)
looping on specs
chaining specs
dependency types/tokens for managing iterations/prev study workspace accessibility (i.e. $(step.workspace) constructs)
new dependency types for steps meant to be run at the same time
- start steps after an initial step is running instead of completed, and close that initial step upon completion of the others
unified resource spec to enable true system portability
composable specs (reuse batch blocks/env bits/etc): new maestro compose [specs] commmand
orchestration (facilities for bootstrapping allocations to submit work to
sub conductors: better coordinate execution in multipel allocations/across machines
non-scalar variable types
- need formatting options for ensuring token replacement generates strings that are useful on cli's
dynamic graphs
- ability to add parameter combos to in progress workflows
- ability to add new steps to existing workflows? (mindful of the provenance implications)
- executed graph not prescribed up front -> conditional steps/loops/branches changing the path insitu
