How VoltGrid 2.0 Operates
01 / INTERPOSITION
Sub-100ns C++ Interceptor
Sits dynamically at the NCCL transport boundary via LD_PRELOAD. Injects hardware CUDA stream barriers without recompiling model code.
02 / SELECTIVITY
Selective Collective Filtering
Inspects buffer sizes to bypass fine-grained layer activations (TP) below 5MB—completely eliminating the latency penalty of naive staggering.
03 / ADAPTABILITY
Residual Jitter Compensation
Measures arrival timing variations and injects only the residual microsecond delay, preventing tail-latency straggler cascade across the cluster.
