DAQ Status Report GlueX Collaboration – Jan , 2009 – Jefferson Lab David Abbott (In lieu of Graham) GlueX Collaboration Meeting - Jan Jefferson Lab

Introduction Projects Hardware/Electronics Front end Back end - Event builder, EMU, etc… Experiment Control and messaging Administrative news etc… GlueX Collaboration Meeting - Jan Jefferson Lab

Hardware/Electronics Reported on elsewhere Highlights: TI Prototype testing – proof of trigger/clock distribution design principle Final TI (v3 this year) will be used with existing experimental program (2.6) as well as support 3.0 DAQ readout. Trigger supervisor has preliminary design but main work not started yet (Note: 128 crate limit) PCI Based TI board - Available with software library support FADC tirgger/readout at 160 KHz. Both FADC, F1TDC revision 2 designs are underway. GlueX Collaboration Meeting - Jan Jefferson Lab

Front end Becoming clear that Intel/Linux is viable for CODA front end. Main effort is rewriting the PPC/VxWorks drivers to for Intel/linux. Currently have a CODA 2.6 ROC running on Linux with VME TI and PCI TI based readout. Can use 6 GeV program and development setups for a “testbed”. Beginning on framework of the CODA 3 ROC and how it communicates with Run Control and Back end (EMU). Increased data rate requirement (3 GB/s) should not be a showstopper.

Front End System FADCF1TDC CPU - GE 7865 Intel Core 2 Duo (2.1GHz) Dual GigE TI (ver 3) CODA 2 & 3 support SD Clock/Trigger Distribution CTP L1 Trigger (optional) VXS Crate 110 MB/s off the CPU on a single GigE link uses only 6% of a single CPU and minimal jitter on front-end response. Linux on the Front End

Back End Prototype parallel EB using EMU framework. Prototype parallel Event Recorder using EMU. EMU control and monitoring now uses cMsg. interface to Run Control (AFECS) started. Start to convert prototypes into something that can be used in a real experiment. Event format decoding/encoding (EVIO). True event building. Look at viable DAQ architectures for staged/parallel event building and future L3 farm. GlueX Collaboration Meeting - Jan Jefferson Lab

Event Format Event recorder (EMU) Has to decode event blocks from EB. has to write data files in EVIO format. Event Builder (EMU) must be able to decode events coming from ROCS or other stages of EB. Must be able to encode headers for full/partial events. GlueX Collaboration Meeting - Jan Jefferson Lab

GLUEX DAQ ACHITECTURE OPTIONS GlueX Collaboration Meeting - Jan Jefferson Lab

Experiment Control AFECS - Java based framework for designing and implementing hierarchical, distributed control systems with intelligent agents. Replaces classic Run Control in CODA 2.6 AFECS now uses cMsg for all internal communication (No JADE left). New “plug-in” support for agent component communication (including EPICS-CA and SNMP). Standardizing component data format for monitoring/display GlueX Collaboration Meeting - Jan Jefferson Lab

Messaging cMsg now mature and being actively used (AFECS, CODA 2.6, Codalite). Version 3.0 released. Internal changes - Bugs being found and fixed More robust handling of lost connections New “payload” support EMU using cMsg for control, monitoring and message logging. GlueX Collaboration Meeting - Jan Jefferson Lab

The good and the bad CODA version 3 is now a BIA Activity: CODA now “critical” to lab operations. More work than people. Downside - Much more paperwork. Upside - Some of the paperwork is actually useful! Have a budget that includes funding to increase DAQ staff – by two scientists. We finally got approval to hire one!! GlueX Collaboration Meeting - Jan Jefferson Lab

The ugly Despite BIA status and full funding lab level management is not approving posting of new positions (“replacements” only). Without extra help projects are slipping relative to the current baseline. Should be further along on several projects, but dealing with 6 GeV operation issues and increasing administrative responsibilities have slowed progress. GlueX Collaboration Meeting - Jan Jefferson Lab

Summary DAQ group is hiring!! BIA funding is a good thing. More formal project management is good. All projects ARE progressing… Those that do not depend on new hires progressing well. Not yet exhausted the “wiggle room” in the schedule Interest outside the lab in CODA related projects could provide additional support/development. E906 experiment at Fermilab plan to use CODA PANDA, NuSTAR, CBM interest in AFECS as control system GlueX Collaboration Meeting - Jan Jefferson Lab
