将深度学习模型的训练从单GPU扩展到多GPU主要面临以下问题:(1)训练框架必须支持GPU间的通信,(2)用户必须更改大量代码以使用多GPU进行训练.为了克服这些问题,本文提出了Horovod,它通过Ring Allreduce实现高效的GPU间通信,而且仅仅更改少量代码就可以实现多GPU训练. TensorFlow中提供了一些分布式训练的API,这些API适用于不同的环境.这就导致用户往往不知道如何更改代码以进行分布式训练,而且debug也很困难.再者,TensorFlow的分布式训练性能与理…

在深度神经网络的分布式训练中,梯度和参数同步时的网络开销是一个瓶颈.本文提出了一个名为TernGrad梯度量化的方法,通过将梯度三值化为\({-1, 0, 1}\)来减少通信量.此外,本文还使用逐层三值化和梯度裁剪加速算法的收敛. 在传统的数据并行SGD的每次迭代\(t\)中,训练数据会被分成\(N\)份以供\(N\)个工作节点进行训练.工作节点\(i\)根据输入样本\(z_t^{(i)}\)计算参数的梯度\(\boldsymbol{g}_t^{(i)}\),之后,工作节点将梯度发送给参数服务器…
