Previous Meeting
- SoLID
- Carl reached out to Zhiwen who responded that they would be having a simulation meeting, but no general software meeting. No other info given.
- DAQ system for SoLID will be different than others at JLab and will likely require our input. Carl will look into who is designing that.
Announcements
- Streaming Readout Workshop VII is happening this week. EPSCI SRO meeting for this afternoon cancelled
SPACK
- Nathan contacted Thomas, but not much movement yet
- David will see about helping.
EVIO-6
- Difficult part of documentation is done.
- Dave A. requested C-API be maintained as is.
- Carl will look at this and make sure documentation and source is updated where needed. Not expected to be a significant amount of work.
JANA2
- GlueX Port progressing. Some issues with factory calls that seem to be unresolved, causing stop conditions. Working trough them.
- ACTS + EIC
- Met with EIC group last week and Nathan updated on current work.
- Path is clear on what is needed next.
- Agreed to meet again in ~3 weeks
AI
- Kishan posted another page on SciComp to describe installing custom kernels for Jupyter. Still a few things to finalize, but mostly there.
- Some new updates posted to JLab AI pages for review (David needs to approve)
- Hydra
- Code jam week before last successful
- The major refactoring of the hydra code is largely done and the system was running
- Some issue with web page updating, but not considered a major problem and should be easily fixed
- Experimental Controls: Two positions entered into Peoplefluent but have not yet been approved
CLARA Support
- Some confusion on how conflicts with parameter names in global and local levels are handled. Some options discussed with Hall-B and it was decided the priorities in the existing code should be left.
SRO
- Indra lab test setup
- Ben R. and Dave A. solved issue with Indra test setup where no hits were being seen in Vardan's testing the previous week
- Testing this week was able to get ~260MB/s or about 1/4 of 10Gbit/s link. Not clear why it wasso limited
- Able to get 1% deadtime fairly quickly with multiple threads, but took several tweaks to get to << 1%
- Aggregate rate of ~600MB/s
- TriDAS
- Sergey B. presented estimation of data rates at HAll-B SRO meeting last week.
- Suggested the current design spec should be for 5GB/s streams with the ability to scale to multiple 5GB/s streams
Offsite
- Production running still at NERSC, PSC, IU. Documentation still needed for new NERSC and IU workflows so it can be handed over to Hall-D postdoc
- OSG sent first jobs into JLab
- Jobs started but had issues running
- May well have fully running jobs by end of week (depends on vacation schedule of key OSG personnel)
