FairSoft

• 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

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)

Current status of tests

• Different scenarios can be tested by changing the configuration

• Documentation for the configuration are available:

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 microslices and 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
