Introduction

These pages help with the overview of the code itself and more detailed documentation of the code itself.

There is Java Documentation that is generated automatically by the code.  This is only as useful as the comments the coder added.

Profiler Output

The output of JProfiler gives a good idea of what is going on in the code. The following profiles are available:

 The two different files were profiled with different methods.
The first one by "sampling", the second one "dynamically", by automatically inserting marker code into the Java for each method.
Sampling is supposed to give a more accurate reflection of the fraction of time spend in a particular method. Dynamic gives the call counts and will include every method, even those that completed quickly. 

Benchmark performed on the first 10,000 events of run 5772 (file 0), on a 2.6 GHz Intel Core i7 laptop.

Documentation 

ComponentMaintainerLocationBrief Description
EvioToLcioJeremy McCormickorg.hps.evioThe main program that converts EVIO to LCIO, performing an LCSim job in the same session. The processed events are then (optionally) written to disk using an LCIOWriter.
LCSimEngRunEventBuilderJeremy McCormickorg.hps.evioThis is the LCSimEventBuilder implementation for the Engineering Run and the Commissioning Run.
EcalEvioReaderSho Uemuraorg.hps.evioConverts various modes of EVIO TDC information into LCSim hit collections.
SvtEvioReaderOmar Morenoorg.hps.evioConverts EVIO SVT data to LCSim hit collections.
