Abstract: ACSIS is the Auto-Correlation Spectrometer Imaging System being developed for the James Clerk Maxwell Telescope and the B-band Heterodyne Array Receiver Project (HARPB). The system has an overall processing rate of 10 MB/sec, with a parallel data-flow architecture, consisting of over 25 processors and 50 real-time tasks that are organized in a distributed concurrent and pipeline fashion. We describe the scheme used by ACSIS, and the JCMT observing system, to co-ordinate these tasks for the collection and reduction of data in real-time.
