Distributed Training

Frameworks and libraries for distributed training

Overview from lambdalabs

  • multi gpu using parameter server: reduce and broadcast done on CPU
  • multi gpu all-reduce in one one, using nccl
  • asynchronous distributed SGD
  • synchronous distributed SGD
  • multiple parameter servers
  • ring all reduce distributed training
