Abstract
Further improving the railway innovation capacity and technological strength is the important goal of the 14th Five-Year Plan for railway scientific and technological Innovation, which includes a comprehensive breakthrough in intelligent railway technology, a marked improvement in safety security technology, and a wide application of green and low-carbon technology. The high-speed rail system tasks need to process huge amounts of data and heavy workload with the requirement of ultra-fast response. Therefore, it is of great necessity to promote computation efficiency by applying High Performance Computing (HPC) to high-speed rail systems. The HPC technique is a nice solution for improving the performance, efficiency, and safety of high-speed rail systems. In this study, through analysis, a comprehensive survey for introducing HPC techniques in high-speed rail systems is reported. These HPC applications are cataloged into four broad categories, namely: fault diagnosis, network and communication, management system, and simulations. Moreover, challenges and issues to be addressed are discussed and further directions are suggested.
