Raw event size study

Short instructions

• Run rawStudy.py in CMSSW (eg. CMSSW_13_2_6_patch2) to get as output several RAW files containing each of them one detector (eg. RawStudy_BPIXp.root). These files will be used to measure the contribution of each detector to the total event size.
• Use makeCircleJSON.py to make an events.json which can be used in Circles (link)

Long instructions

• Make FEDlist.txt from OMS
• Create FEDlist.py using convertFedList.py
• FEDlist.py will be used in rawStudy.py through getFEDList.py
• Run rawStudy.py selecting a proper RAW root file
• You should get files like this

edmEventSize -v RawStudy_BPIXp.root

File RawStudy_BPIXp.root Events 100

• Run makeCircleJSON.py > events.json to create the events.json
• Load events.json in circles/web/data in your Circles website (see (link).
• Copy eventSize.json in your circles/web/groups
• Adapt circle/web/piechart.html and circle/web/piechart.php as follow

         if (config.resource.startsWith("time_")) {
           current.unit = " ms";
           current.title = "Time";
+        } else if (config.resource.startsWith("size_")) {
+          current.unit = " kB";
+          current.title = "Size";
         } else if (config.resource.startsWith("mem_")) {
           current.unit = " kB";
           current.title = "Memory";
