Abstract

This paper presents SOLARIS Edge-to-Cluster Studio, a project in a twenty-project AI infrastructure portfolio. The current repository is an active prototype with implemented behavior, automated correctness tests, and explicit boundaries around unverified hardware or production claims. We describe the system model, current implementation, goals, and evaluation method, then propose five integrations that advance the project toward reproducible system-level validation. A local audit on August 14, 2026 executed 3 project tests successfully. No accelerator, deployment, or performance conclusion is inferred unless a corresponding committed benchmark or profiler artifact exists.

Introduction

SOLARIS Edge-to-Cluster Studio (SOLARIS) addresses a bounded problem within the portfolio’s track-04-robotics-edge track. Its declared status is Active Prototype . The project validates its central mechanism before adding device-specific acceleration, production orchestration, or real-world hardware. This ordering matters because optimization without a trusted reference can make incorrect behavior appear successful.

The project goals are to establish deterministic behavior, encode correctness as tests, create machine-readable evidence, identify limiting resources through measurement, and integrate results with adjacent portfolio systems without losing provenance. The repository contains one paper named exactly after its singular folder: SOLARIS-solaris-edge-to-cluster-studio.tex.

Technical Context

Edge and robotic systems operate under resource, latency, privacy, and safety constraints. Development should progress from deterministic simulation to representative sensors, middleware, and hardware-in-the-loop validation. The portfolio benchmark standard requires environment, workload, method, metric, artifact, reproduction, and limitation fields; unknown values remain explicitly unmeasured .

System Model and Architecture

The prototype is organized around the following domain model:

$$n^*=\arg\min_nL(n,j)\quad\text{s.t.}\quad c_n\geq d_j\land\Pi(n,j)=1$$

The equation is a design and test abstraction rather than a claimed empirical law. It supports invariants and expected-value checks while later implementations replace synthetic inputs with representative workloads or devices.

The software architecture contains an input/configuration layer, a deterministic core, validation and evidence output, and a local visualization. The principal inspected source artifacts are python/placement.py. Unsupported real-world conditions are surfaced as limitations rather than silently simulated.

Detailed Script Operation and Rationale

The placement script models jobs and nodes, filters candidates by capacity and privacy, ranks feasible placements using latency, and explicitly reports unplaceable jobs. It validates orchestration policy before mutable reservations, gateways, cluster adapters, or live workflow state are added.

The execution path is:

1. Construct deterministic job and node models.

2. Reject nodes that violate privacy requirements.

3. Reject nodes without adequate capacity.

4. Rank remaining nodes by latency and select the best feasible target.

5. Return an explicit unplaced result when no safe placement exists.

Implemented Prototype

The metadata and source audit found these completed features :

• Python node/job models

• Capacity, latency, and privacy placement rules

• Unplaceable-job reporting and tests

On August 14, 2026, python3 -m unittest discover -s tests -p ’test_*.py’ completed successfully with 3 tests. The inspected test artifacts are tests/test_placement.py. This is evidence of local correctness for encoded cases, not production scale or hardware performance.

Testing Methodology and Observed Results

Testing uses Python’s standard unittest discovery and exercises the public behavior of the reference implementation. The audit reran the suite from the project folder with python3 -m unittest discover -s tests -p ’test_*.py’. All 3 discovered tests passed. The result establishes correctness only for the encoded local cases; it does not establish accelerator correctness, real-device behavior, production reliability, or benchmark completion.

No numerical performance result is promoted by this test run. Where scripts emit JSON or JSONL, those outputs remain raw or simulation-specific until a reviewed summary includes hardware, software, workload, warm-up, repetition, correctness threshold, Git revision, and limitations.

Claim Boundaries and Risks

The project records these unverified or excluded claims:

• No real edge or cluster orchestration

The main risk is confusing synthetic or modeled behavior with deployed-system behavior. Other risks include incomplete workloads, platform-dependent timing, missing failure injection, and interfaces not yet exercised across device boundaries. Performance claims require a reviewed record meeting the portfolio standard.

Evaluation Plan

Evaluation proceeds through correctness tests, deterministic reproduction with Git and environment metadata, repeated benchmarks reporting latency/throughput/memory/error metrics, and a named profiler capture tied to exact hardware and source revision. Success requires reference equivalence within a documented tolerance, preservation of safety and resource invariants, clear failures, and evidence reproducible from a clean environment.

Goals, Milestones, and Success Criteria

The project goals are staged so that correctness precedes performance and integration. A goal is complete only when its proof artifact is committed or otherwise reviewable; prose or a simulated number alone is insufficient.

Future Work and Integrations

The five project-specific next steps are:

1. Mutable capacity

2. Workflow state view

3. Gateway and cluster adapters

4. Add workflow provenance, retries, reservations, and latency accounting.

5. Use IGNIS as gateway and NEXUS as cluster backend.

The early items complete declared evidence; the later items connect downstream portfolio consumers. Each integration should add tests and a reviewable artifact such as JSONL evidence, a report, profiler capture, deployment manifest, trace, or labeled data set.

Conclusion

SOLARIS Edge-to-Cluster Studio is an evidence-aware active prototype: its implemented behavior and tests are real, while unbuilt hardware, deployment, and performance goals remain labeled. Completing the five integrations in dependency order will advance it from a learning artifact toward a credible portfolio component.
