System Architecture Blueprint

Stage 01

Multi-Stage Layer Partitioning & Pinned Ring Buffers

  • Partitioning 70B to 405B parameter models across sequential GPU nodes
  • Allocating pinned GPU memory ring buffers to prevent memory fragmentation
  • Balancing layer compute latencies across heterogeneous GPU ranks
Engineered Stack: PyTorch 2.4 • CUDA 12.4 • Megatron-LM • DeepSpeed
Stage 02

1F1B Interleaved Micro-Batch Scheduling

  • Interleaving forward and backward micro-batches to bound peak activation memory
  • Configuring virtual stage multiplier v=2 to shrink idle bubble time by 2x
  • Executing asynchronous steady-state scheduling across all pipeline stages
Engineered Stack: 1F1B Scheduler • Zero-Bubble Micro-Batching • Megatron Core
Stage 03

Sovereign GPUDirect RDMA Activation Streaming

  • Bypassing host CPU memory using RoCE v2 and InfiniBand point-to-point transfers
  • Guaranteeing sub-10ms inter-stage latency across multi-chassis clusters
  • Deploying inside sovereign air-gapped private VPCs compliant with Indian DPDP Act 2023
Engineered Stack: GPUDirect RDMA • UCX • InfiniBand • Sovereign VPC
