    Abstract
    During 2017, the CERN Large Hadron Collider (LHC) delivered luminosity for different physics configuration in addition to the nominal 6.5 TeV proton-proton run. About 18.5 days were dedicated to commissioning and delivering special physics configurations to the experiments. VdM runs at 6.5 TeV with high beta-star of 19 m and 24 m for luminosity calibration took place. A dedicated p–p run at 2.5 TeV that provides reference collision data to the experiments for heavy ion (Pb–Pb, p–Pb) collisions at the same energy also took place during the last weeks of November. A very short (0.5 days) but effective ion run was scheduled where the LHC had the first Xe beams colliding and delivering about 3 μb−1 to ATLAS and CMS. The run finished with a low pile-up run at 6.5 TeV. This contribution summarises the operational aspects and delivered targets for the different configurations.

    • 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
