EC Strategy Update 2013

“CERN should undertake design

studies for accelerator projects in a

global context, with emphasis on

proton-proton and electron-positron

high-energy frontier machines.”

Conceptual Design Study

• Form global collaboration
• Study pp/ion collider (FCC-hh)
• Infrastructure driven by FCC-hh
• Study e+e- collider (FCC-ee)
• Understand pe option (FCC-he)

Strategic Goals

• Make funding bodies aware of

strategic needs for research community

• Provide sound basis to policy bodies

to establish long-range plans in European interest

• Strengthen capacity and effectiveness

in high-tech domains

• Provide a basis for long-term

attractiveness of Europe as research area

Fast & Scalable COTS

IO Module IO Module IO Module IO Module IO Module IO Module IO Module IO Module CPU/FPGA chassis CPU/FPGA chassis Frontend Controller

< 5 µsec, > 200 kHz Digital IO:

< 200 nsec 64-128 channels

> 100 k channels, > 10 k modules, > 1 k processors < 5 µsec per value, > 100 values/chassis, > 100 k values 2 k channels / chassis 1 k rules / chassis Analogue IO:

Configurable buffer depths, isochronous data provision, threshold, trending, deadband

Configurable vs. Programmable

• IEC 61131-3 limited for large systems
• Any programming language challenging

for safety-related systems

• Hard-wired functions do not scale
• Configurable model permits concentrating
• n problem domain

– Simple rules, which can be analysed – Parallel processing for highest performance – Automatic distribution

Local Intelligence
