# Benchmarks

|

## 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.

# [CC-CEDICT](https://cc-cedict.org/wiki/)
|
||||
|
||||
What is CC-CEDICT?
|
||||
CC-CEDICT is a continuation of the CEDICT project.
|
||||
The objective of the CEDICT project was to create an online, downloadable (as opposed to searchable-only) public-domain Chinese-English dictionary.
|
||||
CEDICT was started by Paul Andrew Denisowski in October 1997.
|
||||
For the most part, the project is modeled on Jim Breen's highly successful EDICT (Japanese-English dictionary) project and is intended to be a collaborative effort,
|
||||
with users providing entries and corrections to the main file.
|
||||
|
||||
|
||||
## Parse CC-CEDICT to Json format
|
||||
|
||||
1. Parse to Json

it is obviously unnecessary for us to point out how luminous these criticisms are how delicate in expression

on the general principles of art mister quilter writes with equal lucidity
