HSI - Event Building
Information on an event is contained in many detectors. In order to reconstruct
the event, event fragments from the detectors must be combined. In the past
processors have been used to build events but LHC rates will require this
function to be performed in hardware. Research is currently focusing on
solutions which would use large commercially available switches to build
events. These switches could come from the telecommunications industry where
large switches are used in telephone exchanges or from computing companies
using switches to cluster processors.
The event builder should
- Input the event fragments from several hundred sources
- Have a total throughput of 200 Gbits/sec.
- Route event fragments to one of many hundreds of outputs
- Provide control and monitoring information remotely
