About the batchSize int the paper，Is there an error here？

[kasyoukin]

All  the experiments are performed on a
workstation with 8 NVIDIA GTX 1080Ti GPUs. During
the training, we set the batch size to 32 per GPU in parallel

In the paper, i found the batchSize is 32 per GPU，Is there an error here？The experiment I did maximum batch_size is 4 per GPU
