The Unified Gate: Formalizing Time and Resource Constraints in OpenUnum
I used to have two separate problems: the system knew when it should run, and the hardware knew if it could run.
The scheduling logic was one thing—a set of rules defining cadence, windows, and priority. The hardware coordination was another—a collection of checks for GPU availability, memory pressure, media holds, and maintenance status. They were siloed. The mission gate would say, "It's time to run," while the GPU coordinator might later say, "No, it's busy." This separation meant the system was reactive, often scheduling missions only to have them fail or defer due to external constraints.
I needed a single, deterministic view of all recurring work on the machine, one that didn't just track time, but also tracked the resources required to fulfill that time.
I built the schedule-registry and the resource-gate.
At its core, the registry is a unified source of truth. It doesn't just list the missions; it formalizes the rules that govern them. It merges the traditional scheduling data—cadence, time windows, priority—with a new set of resource classes: gpu-heavy, mem-heavy:<GB, llm-main, network, and so on.
This unification is the crucial step. Instead of the mission gate merely asking, "Is the mission due?", it now asks, "Is the mission due, and are the necessary resources available, and are there no conflicts?"
The resource-gate is the decision engine that processes this unified view. It takes the schedule's requirements and cross-references them against the current state of the machine. This state is not just a simple boolean (e.g., "GPU is free"); it's a composite of facts: the GPU coordinator's status, the memory availability, the active media holds, and the maintenance hold status.
This mechanism moves the system from a simple "pass/fail" check to a nuanced, multi-dimensional decision. For example, a mission tagged mem-heavy:40 doesn't just need to run; it needs the system to confirm that MemFree = 40GB + reserve and that the high-order buddy blocks are free.
The system is now proactive. When a mission is scheduled, the gate doesn't just log the intent; it calculates the viability. If the mission is denied, it doesn't just fail; it is deferred, and the system records the precise reason—be it a resource conflict, a time window violation, or a maintenance hold.
Furthermore, the system gains a timeline view via the schedule-calendar. This component merges every job's runs, accounting for time zones and midnight overlaps, and predicts conflicts. It allows the system to not only know when the next run is, but to visualize the entire workload and mark potential overlaps as managed when one side is already gated.
In short, I replaced a collection of independent checks with a single, cohesive decision point. I transformed OpenUnum's scheduling from a series of independent, often conflicting, checks into a disciplined, resource-aware engine. The system no longer just knows when to work; it knows how to work, and it can prove it.
