Online Integration 1-Nov-99 Milestone

This document provides a detailed milestone checklist for the online integration process, focusing on key steps in data taking, event data flow management, and component configuration. It outlines sections on documentation, creating expert guides, startup procedures, and the sequence of operations from initializing applications to halting data taking. Each stage includes checklists for components, including TAKER, EXAMINE, COOR, and DSM, ensuring comprehensive tracking of configuration statuses and event processing for efficient and organized data management.

  1. Online Integration1-Nov-99 Milestone Checklist Last revision: 29-Oct-99 9 AM Send updates to fuess@fnal.gov

  2. Sections • Documentation • Create expert guides • Startup • Applications proceed to initialized state • User interface • TAKER • EXAMINE • Configuration • Sample configuration selected • Begin Run • Data taking initiated • Event data flow • Complete event path • End Run • Data taking halted • SDAQ • Repeat process for SDAQ

  3. Startup • Checklist: • L3 • COOR • COOR connects to L3 • COMICS • COMICS connects to COOR • DSM • DSM connects to COOR • C/R • C/R connects to DSM • DL • DL connects to DSM, C/R • DD • DD connects to DSM, C/R

  4. User Interface • Checklist: • TAKER connects to COOR • COOR assigns Client ID to this connection • EXAMINE connects to DD

  5. Configuration • Checklist: • Define test configuration: • Single Calorimeter crate • Free-run trigger • Single mark and pass trigger • Single stream • Single instances of C/R, DL, DD • TAKER requests, views, and selects a specific configuration from COOR • COOR relays configuration request to COMICS

  6. Configuration (cont’d) • COOR relays configuration request to L3 • COOR relays configuration request to DSM • DSM relays configuration request to C/R • DSM relays configuration request to DL • DSM relays configuration request to DD • DD reports configuration status to DSM • DL reports configuration status to DSM • C/R reports configuration status to DSM

  7. Configuration (cont’d) • DSM reports configuration status to COOR • COMICS reports configuration status to COOR • COOR reports configuration status to TAKER • EXAMINE configuration • Request configuration from DD • Select Trigger, Stream

  8. Begin Run • Checklist: • TAKER sends Begin Run request to COOR • COOR sets run number • COOR sends Begin Run to DSM • Status returned • DSM sends Begin Run to C/R • Status returned • DSM sends Begin Run to DL • Status returned • DSM sends Begin Run to DD • Status returned • DD sends Begin Run to EXAMINE • COOR sends Begin Run to L3 • Status returned • COOR sends Begin Run reply to TAKER

  9. Event Data Flow • Checklist: • Calorimeter crate in free-run mode • L3 processes event • Receives • Puts in EVPACK format • Puts Run, Event, Trigger, Stream numbers in ITC header (fake, where needed) • Sends via ITC to C/R • C/R processes event • Receives • Routes to DL, DD based on Stream number • DL processes event • Receives • Writes to file • Closes file at size limit

  10. Event Data Flow (cont’d) • DD processes event • Receives • Routes to EXAMINE based on Trigger and Stream number • EXAMINE processes event • Receives • Processes • Displays

  11. End Run • Checklist: • TAKER sends End Run request to COOR • COOR sends End Run to L3 • Status returned • COOR sends End Run to DSM • Status returned • DSM sends End Run to C/R • Status returned • DSM sends End Run to DL • Status returned • DSM sends End Run to DD • Status returned • DD sends End Run to EXAMINE • COOR sends End Run reply to TAKER

  12. Pause, Resume Run • Checklist: • much the same as Begin/End

  13. SDAQ • Startup: • Front end processes • Data Merge • Configuration • TAKER selects SDAQ configuration • COOR relays configuration request • Begin Run • TAKER requests Begin Run • COOR relays Begin Run to various elements • Event Data Flow • Front end transmits events to Data Merge • Data Merge transmits events to C/R

  14. SDAQ (cont’d) • End Run • TAKER sends End Run request to COOR • COOR sends End Run to various elements
