# # IMPORTANT NOTE ABOUT RUNNING CARLSUBTRIG # # Carlsubtrig supports the ability to use late arriving station triggers in the # subnet trigger logic. It maintains an internal clock which is set a fixed # number of seconds (the latency period) behind wall-clock (real, system) # time. This latency period allows for delayed delivery of station trigger # messages. Carlsubtrig uses this internal clock to compare to station # trigger times. Once the station trigger-on or -off time is later than the # internal clock time, this trigger status change is noticed by carlsubtrig. In # order for times to be compared between machines, all machines should # be synchronized within a few seconds or better. Xntp (available with # Solaris2.6 and also public domain) is a good choice for time # synchronization. # Because Carlsubtrig uses both system and data time to perform the # subnet trigger logic, the system time must be set to UTC. If this is # not done, no triggers will occur. # Under NT, TZ must be set to GMT in ew_nt.cmd in order to run under # GMT time. # # # CarlSubTrig's Parameter File # # # Basic Earthworm Setup # MyModuleId MOD_CARLSUBTRIG # Module id for this instance of CarlSubTrig - # (WAS MOD_CSU_TEST) Debug 3 # Write out debug messages?
