| Modern distributed training algorithms are designed for HPC networks with 10-100 gigabit per second bandwidth. | |
| In turn, a typical Internet connection runs at 10-100 megabits per second: that’s three orders of magnitude slower. | |
| To make distributed training efficient, you need to win back these three orders of magnitude. | |
| This may seem daunting at first, but in reality, DL researchers have already made all the necessary pieces for solving this puzzle: | |
