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
