Frontend Task

The purpose of a frontend task is to collect data from the hardware and transmit this information to a central place where data logging and analysis can be performed.

A frontend task is built by the user (see Frontend Operation ) and consists of as "user part" and a "system framework"

Arguments

The system framework code (mfe.cxx) has the following arguments:

 [-h hostname ] : host name (see Common Parameters to MIDAS Utilities)
 [-e exptname ] : experiment name (see Common Parameters to MIDAS Utilities)
 [-D ] : Become a Daemon.
 [-O ] : Become a Daemon but keep stdout 
 [-d ] : Used for debugging the frontend
 [-v [level]] : Set verbosity level (as an integer). A bare '-v' implies '-v 1'
 [-i index] : Set frontend index so you can have multiple instances of the same executable running with different names (can be used with Mevb / event builder or standalone).

Usage

Start the application as a daemon, using the default host, experiment and port :

e.g. fevme -D

Start the application superceding the default host, experiment and port:

e.g. fegpib -e exp218 -h isdaq10 -p 7077 -D
