System Architecture Blueprint

Stage 01

Sequence Dimension Sharding & Causal Block-Triangular Pruning

  • Partitioning the sequence dimension across CP discrete GPU ranks into equal token chunks
  • Pruning upper-triangular masked blocks dynamically in autoregressive causal decoding
  • Slashing redundant attention FLOPs by up to 55% across multi-GPU clusters
Engineered Stack: FlashAttention-3 • Causal Mask Pruning • Ring Topology
Stage 02

Asynchronous Peer-to-Peer Ring KV Streams

  • Shifting Key-Value chunks sequentially along the logical GPU ring via non-blocking NCCL send/recv
  • Overlapping cross-GPU ring communication on CUDA Stream 2 with local attention GEMMs on Stream 0
  • Absorbing 96%+ of KV transport latency completely behind local computation
Engineered Stack: NCCL P2P • CUDA Stream 2 • Double-Buffered KV Ring
Stage 03

Sovereign High-Bandwidth Interconnect Fabric

  • Saturating 900 GB/s NVLink 4 intra-node meshes and 400 Gbps InfiniBand NDR inter-node fabrics
  • Sustaining continuous multi-hour 2M+ 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
