Program name : evg
Author : Enrico Pasqualucci
evg is an event generator for KLOE. This application, written in the standard KLOE online enviroment, is able to randomly generate events (between a minimum and a maximum length) at the begin into a memory accessible via VME and shared by n `level-2' chains or into a fifo. During the run, a data length is generated for each chain at the desired rate to tell the event collectors which is the amount of data to read. A trigger number is generated and written into a shared memory location to allow the dfc to work.
The system is synchronous, in the sense that all the level-2 processors must be able to process events at the required rate; otherwise evg will crash.
Usage:

Program name : dfcd
Author : Enrico Pasqualucci
dfcd is the KLOE Data Flow Control Daemon. It is in charge to receive and log traps from the KLOE event building nodes notifying the changes of status ("almost full" or "available") of their internal buffers and to convert them into commands to the Data Flow Control. dfcd is written in the standard KLOE online environment.
Usage:
dfcd [options] [-n procname]
Options:
[-p]
dump snmp packets
Program name : dfc
Author : Enrico Pasqualucci
dfc is the KLOE Data Flow Control program. At the beginning of the run, it is able to build (using SNMP informations) or to retrieve from another process (i.e. run control) the map of the KLOE network. Using this map a `dfc map' is built, containing all the addresses of the nodes where level-2 sub-events have to be sent, in the right order. The dfc map is written in a VME mirrored memory and shared by all the level-2 CPUs.
A dfc table is generated containing a set of dynamic activation flags, meaning the status of the receivers, and and a validation number, i.e. the last trigger number of validity (initially set to 0 = infinity). When a command is received from the dfcd signalling the change of status of a receiver, a new table is generated with the corresponding activation flag changed and a validity number is generated for the previous dfc table.
Usage:
dfc [options] [-n procname]

VME options:
[-va] add
