'''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
 
−
** Currently VTP test setup provides 300MByte/sec/link data rate.
 
−
** Able to get 1% deadtime fairly quickly with multiple threads. For 600MByte/sec aggregated (2 VTP streams) stream processing 2.5 cores are used for aggregation and 4 cores are used for hit finder.
 
−
** 1% dead time that was also present during the beam test was due to the disruptor ring-buffer tuning. Problem solved, but expected to be optimized again for the large data volumes (will see). in coming week/s an additional splitter will be installed to provide ~900MByte/s/link.
 
−
** Aggregate rate of ~600MB/s with no loss of the VTP frames was achieved.
 
−
* 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)
 
−
 
 
−
'''Publications'''
 
−
* Everyone was encouraged to add their most recent publications (including proceedings) to the EPSCI publications page so we can fill in the blank section of the home page.
