### Git can't do this natively, but you can use git in combination with another command, such as GNU xargs
_First of all, fetching many repos in parallel is likely not worth it._ Git fetch is likely to be limited by network speed or drive IO speed, not single core processing speed. Multiple instances of git will compete with each other for these resources, so running them in parallel could take more total time than running them serially.
With that said, you can use git to quickly get a list of submodules, then pipe that list to another command which can launch many instances of git in parallel. For example:
```
git submodule foreach pwd \
| xargs -I{} --max-procs=8 git -C {} pull
```
