System Architecture Blueprint

Stage 01

Uniform Sequence Sharding & Local Query Partitioning

  • Partitioning token sequence length S uniformly into S/N chunks across N distributed GPUs
  • Bounding per-GPU activation and key-value memory allocations linearly
  • Holding invariant local query projections Q_i throughout ring shift iterations
Engineered Stack: PyTorch 2.4 • CUDA 12.4 • Megatron-LM • FlashAttention-3
Stage 02

Asynchronous Ring Self-Attention P2P Streaming

  • Streaming Key-Value blocks (K_j, V_j) in a logical peer-to-peer ring across neighbor ranks
  • Overlapping non-blocking NCCL P2P communication with local chunked GEMM attention compute
  • Achieving over 96% communication overlap ratio on high-speed fabrics
Engineered Stack: NCCL 2.21 • CUDA P2P Streams • RingAttention Kernel
Stage 03

Sovereign Private Cloud & High-Bandwidth Fabric

  • Deploying over 900 GB/s NVLink intra-node meshes and 400 GB/s InfiniBand NDR inter-node fabrics
  • Sustaining continuous multi-hour 1M+ context reasoning without accuracy degradation
  • Deploying inside sovereign air-gapped private VPCs compliant with Indian DPDP Act 2023
Engineered Stack: NVLink 4 900 GB/s • InfiniBand NDR 400 GB/s • Sovereign VPC
