Abstract
HD (Large Helical Device) is a superconducting fusion experimental device which enables steady-state plasma sustainment. Its data system, namely “LABCOM system”, has been fully equipped with high-throughput realtime data acquisition (DAQ), streaming, and archiving capabilities [1][2]. To deal with more than 100 MB/s stream, large shared memory is primarily used for inter-process fast and massive data handlings. Multitasking and multithreaded subtasks are implemented for every I/O device in each DAQ frontend [3].
