  1. Status of the ALFA/FairRoot Mohammad Al-Turany

  2. ALFA/FairRootactivites • Framework level • Modularity • Serialization • DDS and Topology • Prototypes and benchmarks • New Prototype for CBM FLES • Benchmarks with O2 on the DAQ test cluster • Benchmarks with O2on the GSI test cluster • Parameter management in ALFA M. Al-Turany, ALICE offline week

  3. FairSoft Improve modularity • New installation option for FairSoft • ./configure mqonly • Only CMake, BOOST, ROOT, ZMQ, gtest , gsl are build • Exclude Geant3/4, Millepede, VMC, VGM, pluto, HEPMC, Pythia6/8 > git clone https://github.com/MohammadAlTurany/FairSoft/ > git checkout MQ_only M. Al-Turany, ALICE offline week

  4. FairRoot/ALFA Improve modularity • New installation option for FairRoot • Cmake-DRECO_ONLY=1 • Exclude simulation and event generators M. Al-Turany, ALICE offline week

  5. Currently implemented and ready to use transport formats • Boost serialization • Protocol buffers • Root serialization M. Al-Turany, ALICE offline week

  6. Current status of tests • Examples are installed on the test cluster • Example scripts are available on the gateway machine : • /local/home/cwg13/new_test_21.05.2014/single/ • Message (part) size can be set from script • Message part size = 40 x eventSize (Bytes) M. Al-Turany, ALICE offline week

  7. Current status of tests • Different scenarios can be tested by changing the configuration • Documentation for the configuration are available: https://github.com/FairRootGroup/FairRoot/tree/dev/example/Tutorial3/macro M. Al-Turany, ALICE offline week

  8. Nicolas Winkler Proto type for CBM FLES • A Prototype which read simulated data, fill the RAW data format and send it on the wire is implemented for the CBM experiment • BOOST serialization is used • Sampler: • which read the root files produced by the cbmroot simulation and convert the data in the FLES format and fill the STS microslices • Processor: • which get the STS microslicesand merge them into one timeslice • Filesink: • which get the timeslices M. Al-Turany, ALICE offline week
