The China Spallation Neutron Source (CSNS) accelerators consist of an 80 MeV H− linac and a 1.6 GeV proton rapid cycling synchrotron (RCS), which provides beam to the target at repetition rate 25 Hz. commissioning CSNS had been started since April 2017, end February 2020, reached design power 100 kW. most important issue in high-power is loss control, as well control induced activities, meet requirement manual maintenance. A series optimization work done reduce uncontrolled loss. Transverse...

Vision Transformers are being increasingly deployed in safety-critical applications that demand high reliability.Ensuring the correct execution of these models GPUs is critical, despite potential for transient hardware errors.We propose a novel algorithm-based resilience framework called ALBERTA allows us to perform end-to-end analysis and protection transformer-based architectures.First, our work develops an efficient process computing ranking transformers layers.Due large size transformer...
