Data Parallelism示意图 数据并行可以提高训练效率,其过程如下: 将模型参数拷贝至各个显卡上,即上图中各个显卡都拥有相同的模型参数; 将采样的mini-batch数据均等拆分至各个显卡上; 各个显卡独立完成前向传播和反向传播,得到对应的梯度(此时,各个显卡上的梯度并不相同); 通过一次 AllReduce 操作,将各个显卡上的梯度进...
1. GPU与CPU集群上Model/Data Parallelism不存在本质上的区别，更多是存在工程细节上的区别。对这些工程...
Data Parallelism VS Model Parallelism in Distributed Deep Learning Training 分布式训练一(入门介绍) 深度学习中的分布式并行介绍
Then I want to use data parallelism and do not use model parallelism, just like DDP. The load_in_8bit option in .from_pretrained() requires setting device_map option. With device_map='auto', it seems that the model is loaded on several gpus, as in naive model parallelism, which ...
Using .NET4 Parallel Programming Model to Achieve Data Parallelism in Multi-tier ApplicationsOne reoccurring pattern that most application developers encounter is that of applying a set of business rules to large amounts of data. When developing such applications, developers face the ard...
Existing MoE systems support only expert, data, and model parallelism or a subset of them. This leads to three major limitations: i) They replicate the base model (part of the model without expert parameters) across data-parallel GPUs, resulting in wasted memory, (ii) They ne...
Loop unrolling done by the C++ compiler can expose more instruction-level parallelism, but can also create more live variables that the optimizer needs to track for register allocation. The CLR JIT can only track a fixed number of variables for register allocation; once it has to track more th...
It combines model parallelism (tensor slicing) and pipeline parallelism with data parallelism in complex ways to efficiently scale models by fully leveraging the aggregate GPU memory and compute of a cluster. 3D parallelism has been used in DeepSpeed (opens in new tab) and ...

Statecharts: An advanced form of finite state machines (FSMs) that supports complex transitions, parallelism, and hierarchical states. Often used to model reactive systems like embedded devices and user interfaces. Markov Models: Represent probabilistic system behavior where state transitions are governed ...
