+- Observation 2: The coefficient of variation of throughput for the 100 iterations is smallest when batch_size = 128.  
+Benchmarking with batch_size = 128 can be used for node health check. For example, the expected throughput for dim = 2, nodes = 1, gpus = 4, batch_size = 128 would be 2500 ± 200.
