18 | * @defgroup alihlt_system HLT integration into AliRoot | |
19 | * This section describes the HLT integration into AliRoot. | |
fb345ed7 | 20 | * |
21 | * @section alihlt_system_intro General Remarks | |
22 | * The HLT analysis is organized in components which can also be used | |
23 | * in off-line processing. Two different types of off-line applications | |
24 | * can be distinguished: | |
25 | * - AliRoot simulation (AliSimulation) | |
26 | * - AliRoot reconstruction (AliReconstruction) | |
27 | * | |
28 | * The foundation of the off-line applications is a HLT chain described | |
29 | * by the means of AliHLTConfiguration. Special components exist, which | |
30 | * emulate the behavoir of the components of the HLT on-line data | |
31 | * transportation framework. Together with the analysis components, this | |
32 | * allows the full emulation of the behavoir of HLT analysis chain off-line. | |
33 | * | |
34 | * More details how to setup up such a chain can be found: | |
35 | * - The examples page under @ref tut_hltsystem | |
36 | * | |
37 | * @section alihlt_system_simulation AliRoot simulation | |
38 | * HLT has a special role in the normal data flow of simulation and | |
39 | * reconstruction. Since the HLT reconstruction and analysis runs on-line | |
40 | * on the HLT farm, the raw data produced by HLT as a detector contains | |
41 | * already reconstructed events. Consequently, the HLT response has to be | |
42 | * simulated as well as the data of all other detectors. | |
43 | * | |
44 | * Since the detector data is needed, the HLT simulation is run at the | |
45 | * end of AliSimulation. | |
46 | * | |
47 | * As a matter of fact, HLT always reconstructs data, <em><b>HLT simulation | |
48 | * </b></em> means <em><b>HLT reconstruction embedded into AliRoot</b></em>. | |
49 | * | |
50 | * More Details an be found in the module: | |
51 | * - @ref alihlt_aliroot_simulation | |
52 | * | |
53 | * @section alihlt_system_reconstruction AliRoot reconstruction | |
54 | * | |
55 | * Like all other ALICE detectors, HLT utilizes the AliReconstruction interface | |
56 | * to implement a plugin for the AliRoot reconstruction. The reconstructor can be | |
57 | * used to | |
58 | * - run HLT analysis chains in the AliRoot reconstruction <br> | |
59 | * This option is mainly intended for the development and debugging cycle. HLT | |
60 | * chains can be defined by means of AliHLTConfiguration and can be run either | |
61 | * stand-alone or embedded into the AliReconstruction cycle. | |
62 | * - run the default analysis chains <br> | |
63 | * HLT modules can define default analysis chains to be run during AliRoot | |
64 | * reconstruction. | |
65 | * - handle the HLTOUT data<br> | |
66 | * The HLT output stream contains multiple data blocks produced by the various | |
67 | * components of the HLT chain. Each block might need different and even | |
68 | * detector specific processing, like e.g. the processing of ESD objects or the | |
69 | * handling of compressed data. | |
70 | * | |
