Abstract

Modeling and analysis play essential parts in a Cyber-Physical Systems (CPS) development, especially for the system of systems (SoS) in CPS applications. Many of today’s proposed CPS models rely on multiple platforms. However, there are massive reusable components or modules in the different platform. And also, the model had to be modied to meet the new system requirements. Nevertheless, existing time model technologies deal with them, but it leads to a massive time consuming and high resource cost. There are two objectives in this paper. One is to propose a new simple and proximate time model (SPTimo) framework to the practical time model of hybrid system modeling and analysis. Another is to present a time task scheduling algorithm, mix time cost and deadline first (MTCDF) based on computation model in the SPTimo framework. Simulation results demonstrate that the MTCDF algorithm achieves the priority the scheduling of tasks with a time deadline, and match with optimal scheduling in time requirement and time cost.

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
