Lab: Symmetric Memory and NVSHMEM Patterns
Show why persistent symmetric buffers matter for GPU-driven communication patterns.
Baseline
Section titled “Baseline”The baseline allocates and registers a transfer buffer for each operation and uses a CPU rendezvous for every exchange.
Optimized
Section titled “Optimized”The optimized path allocates a symmetric pool once and reuses stable offsets for repeated exchanges.
python compare.pyExpected Observation
Section titled “Expected Observation”The optimized path should reduce setup count and per-operation latency while preserving the same payload checksum.
