基于CUDA的多GPU加速SART迭代重建算法
High Power Laser and Particle Beams（2013）
Abstract
为解决SART迭代重建算法计算耗时的问题,在单GPU基础上,利用多块GPU的并行计算能力,提出了一种多GPU加速迭代重建算法。实验结果表明,与CPU重建相比,在不影响重建图像质量的情况下,采用GPU重建速度有明显提高,且增加GPU数量可以进一步提高重建速度。

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
