9 # This script contains the ancillary classes and functions used in the
10 # GaudiPython Parallel model
11 #
12 # Classes :
13 # - HistoAgent : In charge of extracting Histograms from their Transient Store
14 # on a reader/worker, communicating them to the writer, and on
15 # the writer receiving them and rebuilding a single store
16 #
17 # - FileRecordsAgent : Similar to HistoAgent, but for FileRecords Data
18 #
19 # - LumiFSR : FSR data from different workers needs to be carefully merged to
20 # replicate the serial version; this class aids in that task by
21 # representing an LHCb LumiFSR object as a python class
22 #
23 # - PackedCaloHypos : Pythonization of an LHCb class, used for inspecting some
24 # differences in serial and parallel output
25 #
26 # - Syncer : This class is responsible for syncing processes for a specified
27 # section of execution. For example, one Syncer object might be
28 # syncing Initialisation, one for Running, one for Finalisation.
29 # Syncer uses multiprocessing.Event() objects as flags which are
30 # visible across the N processes sharing them.
31 # IMPORTANT : The Syncer objects in the GaudiPython Parallel model
32 # ensure that there is no hanging; they in effect, allow a timeout
33 # for Initialisation, Run, Finalise on all processes
34 #
35 # - SyncMini : A class wrapper for a multiprocessing.Event() object
36 #
37 # Methods :
38 # - getEventNumber(evt) : pass a valid instance of the GaudiPython TES
39 # ( AppMgr().evtsvc() ) to this to get the current
40 # Event Number as an integer (even from RawEvents!)
