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


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

FairRoot/ALFA

Improve modularity

  • New installation option for FairRoot

    • Cmake-DRECO_ONLY=1

  • Exclude simulation and event generators

M. Al-Turany, ALICE offline week


Currently implemented and ready to use transport formats

  • Boost serialization

  • Protocol buffers

  • Root serialization

M. Al-Turany, ALICE offline week


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


Current status of tests

  • Different scenarios can be tested by changing the configuration

  • Documentation for the configuration are available:

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

Next steps:

  • Port code from the HLT to O2 prototype

  • Test different scenarios for the FLP/EPN configurations.

  • Use the HLT dev Cluster for testing
