Acceleration with Multi-GPUs
We compare the training time with 1, 2, 4, 8 Tesla V100 GPUs (with a subset of LibriSpeech samples whose audio durations are between 6.0 and 7.0 seconds). And it shows that a near-linear acceleration with multiple GPUs has been achieved. In the following figure, the time (in seconds) cost for training is printed on the blue bars.
| # of GPU | Acceleration Rate |
|---|---|
| 1 | 1.00 X |
| 2 | 1.98 X |
| 4 | 3.73 X |
| 8 | 6.95 X |
