This list of responsible being attached to alarm message strings will be great for the
mmessenger, however, perhaps its going to generate very long messages for the speaker programs

At DANCE we have a similar issue. We are still doing "software

At Los Alamos, we have 15+1 frontends - the 15 between them read about 2 or 3
TB/hour and reduce it to 1 to 5 GB/hour which is then sent to the mevb on a 17th
computer. The 16th frontend handles deadtime issues and scalers (small data rate).
