THE DAQ COMPONENTS

Midas Network Server

The WFD frontend and CAEN frontend send asynchronous buffers of Midas events from the frontend processors across the local network to the backend processors. On the backend processor a corresponding number of mserver sub-processes are listening on specific ports for incoming packets of Midas data from the Midas frontends. On receipt the packets are deposited into corresponding shared memory segments denoted BUF1 for the WFD frontends and BUF7 for the CAEN frontend.

The mserver sub-processes are started by typing mserver. The Midas frontend's identify the destination machine via the "-h be01" argument and the destination experiment via the "-e mulan" argument.
