The implementation of the machine learning system in the academic and commercial domains has been accelerated by basic models in the domains of natural language processing and computer vision. Researchers have suggested increasing the parameter count by orders of magnitude to extract additional capabilities from these models and train on vast corpora of data. Its main features of self-regulation and adaptability allow a wide range of applications to be developed to address particular problems, including text production, sentiment analysis, image segmentation, and image recognition.
Due to physical and power limitations, the underlying hardware used to train such huge models must scale proportionally to the model parameters. Various techniques have been investigated to overcome this computational challenge, including network restructuring, network pruning, network quantization, distillation of low-rank decomposition knowledge, model scattering, etc. Different types of sparse approaches have been proposed to reduce computation intensity and mimic connections. between neurons in the human brain. The underlying hardware architecture presents new difficulties as scattering methods advance and is widely used in training and inference applications.
A well-balanced system must tolerate fluctuations between a model implementation that is typically very computationally dense and very sparse memory. Because there are so many potential patterns and training streams, sparse computations require the flexibility, programmability, and efficiency of next-generation hardware rather than just adding Tera-FLOPs and memory bandwidth to meet computational demands. of machine learning. A good implementation of lightweight methods in a friendly architecture can effectively help overcome current barriers such as huge power, high machine costs, and long training times.
Numerous computational frameworks have been proposed in response to the growth of machine learning and artificial intelligence applications and their inherent properties. In addition to conventional CPU-based architectures, some examples are Google TPU, NVIDIA A100 Nvidia, Cerebras CS-2, Graphcore IPU, and SambaNova RDU. The full extent of the capabilities of these hardware and software systems remains to be discovered, particularly in handling a wide spectrum of sparse and dense applications, despite some attempts to evaluate and compare these systems. Furthermore, many of these frameworks remain privately owned and are not accessible for public research in the public domain. Although promising, the sparse approaches have additional difficulties in addition to architectural compatibility.
The accuracy of a particular model, as opposed to a dense-only baseline, depends on a wide range of factors, including structured, semi-structured, and unstructured scarcity, percentage scarcity/scarcity activation weights, and schedule. of training. These decision factors must be determined to get the most up-to-date metrics on a particular model, which requires time and effort. Large language models, which can be adapted to a variety of language applications, are popular basic models in the NLP industry, such as the 13B GPT parameter. The SambaNova Systems researchers in this study use this model to demonstrate how scarcity can be successfully included in an end-to-end training loop to achieve equivalent accuracy metrics.
They contribute in the following significant ways:
• A comprehensive examination of how data scattering, merging, and flow capabilities interact.
• A demonstration of speedups on A100 using sparse GPT 13B on SambaNova RDU.
• Analysis of the 13B GPT sparse model’s sparse model 13B GPT stall, zero shot, and undershot statistics compared to its dense baseline.
