System Architecture Blueprint

Stage 01

Top-k Dynamic Gating & Expert Sharding

  • Routing tokens dynamically to top-k active experts using softmax gating with auxiliary balancing loss
  • Sharding feed-forward expert networks across N distributed GPU ranks (EP degree)
  • Enforcing dynamic capacity factor multipliers to eliminate token drop risk under peak concurrency
Engineered Stack: PyTorch 2.4 • CUDA 12.4 • Megatron Core • DeepSeek MoE
Stage 02

Asynchronous All-to-All Dispatch & Combine Streams

  • Pipelining token dispatch into micro-batches over non-blocking NCCL all-to-all streams
  • Overlapping cross-GPU token exchange with self-attention projection GEMM computations
  • Combining expert outputs concurrently with residual stream additions
Engineered Stack: NCCL 2.21 • CUDA Non-Blocking Streams • Pipelined Micro-Batches
Stage 03

Sovereign NVLink 4 & InfiniBand Fabric

  • Saturating 900 GB/s NVLink intra-node meshes and 400 GB/s InfiniBand NDR inter-node networks
  • Slashing cross-rank all-to-all dispatch latency under 1.8ms at wire speed
  • 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
