It seems that you could discuss that, at least on RTEMS, the scan threads might run above the RTEMS network threads in priority because the EPICS scan threads do not call directly into the network stack, and their periodicity should perhaps not be disturbed by network loading.
Good point.This would make the scan threads applicable to harder real-time applications -- assuming that the iocsh thread priority was reduced, too.
Of course the issue of starvation of network/iocsh threads again arises. This is tricky stuff.... -- Eric Norum <[email protected]> Department of Electrical Engineering University of Saskatchewan Saskatoon, Canada. Phone: (306) 966-5394 FAX: (306) 966-5407
