Euroball III Data Acquisition
Histogram Server
The Histogram Server is based on a set of workstations connected to the FCS switch. It receives output from the processor farm and constructs histograms as requested by the analysis program running on the farm. Histograms are initially cached in RAM and then from time to time dumped to disk. The histograms can be retrieved at any time for viewing.
The same access method as used for the hardware histogrammer will be used thus enabling the histogram viewer and analysis codes to freely mix online hardware and software histograms with offline histograms.
