Next: Slice Test DAQ Setup
Up: l1joint_0301_rcdb
Previous: Crate Controller (1)
Proposed Setup
- ``Local Controller'' for each crate, running on the crate CPU
- Online Software services (eg DB access) required in all crates
- CPUs may be diskless (boot from L1Calo server) or may have
local disks. [To be decided: question of data/software
distribution vs network performance]
Controller Responsibilities
- Read run parameters from IS
- Load hardware configuration and other databases
(some may depend on run type?)
- Implement actions for each state transition
- Separate thread/process for monitoring modules
in the crate (eg link errors, PP rates?)
- Update crate status in IS
