System Architecture Blueprint

Stage 01

Dynamic Entropy & Memory Hole Detection

  • Continuously tracking GPU physical memory block allocation entropy across tenant request streams
  • Identifying non-contiguous 2MB physical pages released by finished generation sequences
  • Triggering asynchronous compaction when external fragmentation crosses threshold limits
Engineered Stack: CUDA 12.4 • vLLM • C++20 • PyTorch 2.4
Stage 02

Zero-Copy CUDA cuMemMap Virtual Remapping

  • Leveraging CUDA Virtual Memory Management APIs to reserve and map virtual address descriptors
  • Coalescing physical HBM memory pages without performing blocking host-to-device or device-to-device copies
  • Preserving active attention tensor pointers with zero CUDA kernel invalidation
Engineered Stack: CUDA Driver APIs • TensorRT-LLM • SGLang • Custom Kernels
Stage 03

Sovereign Enterprise FinOps Governance

  • Maximizing multi-tenant request density on sovereign private on-premise H100 clusters
  • Enforcing strict statutory memory isolation compliant with Indian DPDP Act 2023
  • Deploying within sovereign tier-4 datacenter VPCs in Mumbai and Bangalore
Engineered Stack: FastAPI • Prometheus • OpenTelemetry • Sovereign VPC
