Power governance for neoclouds & GPU-as-a-Service
Neocloud · GPU-as-a-Service
Prove every power action to every tenant — without exposing the others
As a multi-tenant GPU provider, you sell capacity on shared infrastructure — and your tenants increasingly expect proof that power actions on the racks they rent were governed. Spark-XC sits above your multi-tenant scheduler (Run:ai, Slurm, Kubernetes) and NVIDIA Mission Control as a governance layer. Mission Control executes. Spark-XC validates.
Spark-XC ties every governed power action to the tenant and workload that caused it through workload context validation, then commits a per-tenant Power Event Record on an append-only, SHA-256 tamper-evident chain. Chargeback is grounded in measured power deltas, SLA compliance is replayable, and no tenant's evidence is ever visible to another.
- Sits above Run:ai, Slurm, Kubernetes, and Mission Control — no rip-and-replace
- Every action tied to its tenant and workload through workload context validation
- Per-tenant Power Event Records make chargeback provable, not asserted
- SLA compliance is replayable from the evidence chain, not reconstructed
- Evidence is isolated per tenant — zero cross-tenant leakage

Neocloud Scenarios
Real tenant situations, governed and proven
Scenario · Billing
Tenant disputes a chargeback line
A tenant challenges a power-based charge on their monthly invoice, claiming the capping action that drove it never happened. You replay that tenant's Power Event Records for the period — each with the measured power delta, the workload that caused it, and a chained hash — and resolve the dispute from evidence rather than assertion. No other tenant's records are touched or exposed.
Dispute closed by replaying per-tenant PERs. Chargeback defended.
Scenario · Multi-Tenant Operations
Noisy-neighbor power cap authorized and proven
One tenant's runaway job drives a rack toward its power envelope, threatening neighbors on shared infrastructure. The scheduler requests a cap; Spark-XC validates it against GPU telemetry, facility power, and the policy gate, authorizes it, and commits a Power Event Record attributed to the originating tenant — so the protective action is both governed and attributable.
Cap authorized in real time. Attribution recorded to the right tenant.
Scenario · SLA
SLA-breach claim adjudicated from evidence
A gold-tier tenant files an SLA claim, asserting a power action degraded their throughput. You replay the Power Event Records for their workload and show the validated sequence — what was requested, what was applied, the readback, and the workload context — proving whether the SLA was preserved or breached. The adjudication rests on a tamper-evident chain, not on screenshots.
Claim adjudicated from the chain. SLA proof, not SLA argument.
Scenario · Audit
Per-tenant audit export for due diligence
A tenant's compliance team requests an export of every governed power action that touched their allocation. Spark-XC produces a per-tenant, tamper-evident export — scoped strictly to that tenant's Power Event Records — that an auditor can independently replay and verify against the hash chain. Other tenants' data never enters the export.
Scoped, tamper-evident export delivered. Zero cross-tenant exposure.
How It Works
From a shared power action to per-tenant proof
Path 2
Per-Tenant Attribution
Spark-XC validates each governed power action against the workload that caused it — which job, which tenant, which SLA tier. It sits above Run:ai, Slurm, Kubernetes, and Mission Control, so a power action carries the tenant and scheduler context that explains who it belongs to.
Why it matters for neoclouds
On shared infrastructure, the same power action means different things to different tenants. Tying every action to its tenant is what turns a raw watt-figure into a billable, defensible record instead of an unattributed number.
Path 3
Chargeback You Can Defend
Each Power Event Record carries the measured power delta — requested, applied, and read back — correlated to facility power. Chargeback is grounded in what the hardware actually did, not in modeled estimates or after-the-fact allocation.
Why it matters for neoclouds
When a tenant disputes a power-based charge, "the model says so" is not an answer. A measured delta on a tamper-evident chain is. Provable chargeback reduces disputes and protects margin.
Path 1 · 2
SLA Proof
Every governed action is checked against live GPU telemetry and the workload's SLA tier before it is authorized, and the validated sequence is committed as a Power Event Record. SLA compliance is replayable from the chain — not reconstructed from fragmented logs after a complaint.
Why it matters for neoclouds
SLA disputes are won or lost on evidence. Replaying the exact validated power sequence for a tenant's workload turns a contested claim into a settled fact in minutes.
Path 5
Multi-Tenant Isolation of Evidence
Power Event Records are scoped per tenant on the append-only, SHA-256 hash-chained ledger (ARIV). Replay, export, and audit operations are bounded to a single tenant's records — so proving an action to one tenant never reveals another's workloads, allocations, or power behavior.
Why it matters for neoclouds
Isolation is the product. The ability to prove governance to one tenant with zero leakage to its neighbors is what makes shared infrastructure sellable to security-conscious buyers.
Path 4
Sits Above the Scheduler
Spark-XC is a governance layer above your multi-tenant scheduler and Mission Control — not a replacement for them. Power requests from Run:ai, Slurm, or Kubernetes pass the policy and approval gate before authorization, and out-of-band changes are detected, reconciled, and recorded.
Why it matters for neoclouds
You keep the orchestration stack your tenants already run. Spark-XC adds the validation and per-tenant proof on top, so adopting governance does not mean re-platforming the fleet.
Neocloud
Make per-tenant power provable
Bring a real power action from your multi-tenant fleet and we'll replay its Power Event Record — approved, safe, auditable, financially real, and attributed to the right tenant. We work with neocloud and GPU-as-a-Service operators to fit Spark-XC above the scheduler you already run.
