在深度学习训练中,随着模型复杂度和数据集大小的增加,单个GPU或CPU的计算能力可能无法满足训练需求。为了加速训练过程和提高模型的准确性,可以采用模型并行处理(Model Parallel Processing)的方法。模型并行处理是一种将模型分散到多个GPU或CPU上进行计算的技术,可以实现并行计算,提高计算效率和模型训练速度。模型并行
MPP的编程模型可以是SIMD,SMM/NUMA,DMM(Distributed Memory Model)等。 然后总结了下第二波浪潮中的创新,包括VLIW,多处理器间的同步(如DOACROSS的loop sync),SMT(Simultaneous Multithreading),NUMA和COMA。关于这些创新点具体些的讨论可以看原文,都挺有意思的。总结地,这些start-up的许多非凡实验都使用了如今可见的...

1.1The Missing Parallel Computation Model The goal of a computation model is to establish an abstract and theoretical framework for describing and evaluating algorithms in a way that predicts their performance on real computers. Moreover, the main role of acomputational modelis to serve as a bridgi...
Parallel-computer models that are used for correctness and performance analysis are simple extensions of stored-program models. The two models that are used are the shared-memory model and the distributed-memory model (Figure 1). In the first model, a common memory is shared by all processors;...
Our application operates on a file directory structure and loads each file’s content into memory. Thus, we need the following classes to represent this model. A document is represented as a list of lines: Copy Copied to Clipboard Error: Could not Copy class Document { private final List<Str...

A parallel computer is a group of homogeneous processing units that solve large computational problems more quickly through communication and collaboration. Common parallel computer architecture includes a shared memory symmetric multiprocessor, a distributed memory massively parallel machines, and a loosely ...
