L40S (48GB) and H100 (80GB) have plenty of headroom; the 2GB cap was a conservative leftover that tripped on workflow zgjgc with 17.8M imbalance bars (3.2GB). 8GB budget leaves ~28GB free on L40S after model + activations + workspace. Updates both call sites: - DqnGpuData::upload_slices (training data, the failing one on zgjgc) - PpoGpuData::upload (market data, same constant) Error message format strings updated 2.0 GB → 8.0 GB.
