在Megatron1, 2中,Transformer核的TP通信是由正向两个Allreduce以及后向两个Allreduce组成的。Megatron 3由于对sequence维度进行了划分,Allreduce在这里已经不合适了。为了收集在各个设备上的sequence parallel所产生的结果,需要插入Allgather算子;而为了使得TP所产生的结果可以传入sequence parallel层,需要插入reduce-scatter...
However, each of these do not consider all the parallelism dimensions considered in this paper: pipeline and tensor model parallelism, data parallelism, microbatch size, and the effect of memory-savings optimizations like activation recomputation on the training of models larger than the memory capaci...

The interleaved pipelining schedule (more details in Section 2.2.2 ofour paper) can be enabled using the--num-layers-per-virtual-pipeline-stageargument, which controls the number of transformer layers in a virtual stage (by default with the non-interleaved schedule, each GPU will execute a sing...

the team at DeepMind released a paper detailing the training and performance of their model.The problems with the model are many. One of the biggest issues is that grammatical rules are ambiguous. For example, the phrase ”I came down” could mean I came down from the stairs, or I came ...
