Platform Overview

The control plane your GPU infrastructure has been missing

SPARK-XC is a patent-pending GPU infrastructure control plane — governing power limits, safety policies, and fleet state through five independent enforcement layers, with cryptographic proof of every decision.

Core Capabilities

Everything your GPU fleet needs to stay safe

🔩
Hardware-Level Clamping
Enforces power limits directly at the register level — below the operating system. Remains active even when drivers or software stacks fail.
🌡️
Thermal Emergency Response
Real-time sensor polling with sub-2ms response. Triggers immediate power reduction on threshold breach — faster than any software watchdog can react.
⚖️
Governance Gates
A configurable policy engine evaluates every power request against your ruleset before execution is permitted. No request bypasses the gate.
✅
Execute and Verify
After every power limit change, SPARK-XC reads back the hardware register to confirm the intended state was actually applied. Zero silent failures.
🔐
Cryptographic Audit Logging
Every action is HMAC-SHA256 signed and chained to its predecessor. A forensically complete, tamper-evident record of every power management decision — ever.
⚡
Independent Failure Isolation
Each layer operates in isolation. A fault in any one layer cannot cascade. The remaining layers continue enforcing safety without interruption.
How It Works

From request to enforced

Every GPU power limit request flows through the full SPARK-XC pipeline — intercepted, validated, executed, and permanently recorded.

1
Request Arrives
A user application, scheduler, or operator submits a power limit request via the standard driver interface.
2
Hardware Clamp Applies
Layer 1 enforces the absolute hardware-registered ceiling — no request can exceed it, regardless of what software asks.
3
Thermal Check
Layer 2 evaluates current sensor readings. If thermal limits are approaching, an emergency reduction is triggered immediately.
4
Policy Gate Evaluated
Layer 3 runs the request against your governance ruleset. The request is either approved, modified, or rejected.
5
Applied and Verified
Layer 4 executes the approved change and reads back the register to confirm the new state was applied correctly.
6
Logged and Chained
Layer 5 appends a cryptographically signed, chained audit entry — immutable, tamper-evident, always available.

Why SPARK-XC

Traditional GPU safety vs. defense-in-depth

⚠️ Traditional Approach
  • Single software layer — one failure = no protection
  • Driver or OS fault exposes hardware
  • No hardware register verification
  • Logs are mutable and often incomplete
  • No policy engine — any request is honored
  • Silent failures go undetected
⚡ SPARK-XC
  • Five independent layers — each sufficient on its own
  • Hardware clamping survives driver/OS failure
  • Register readback verifies every action
  • HMAC-SHA256 chained, tamper-evident audit log
  • Configurable governance rules — every request evaluated
  • Verification layer catches and logs all failures
