Minutes:
Attendees: David L., Carl T., Nathan B., Kishan R., Vardan G., Graham H., Thomas B.
SPACK
- Wouter contacted Thomas recently asking for info. about the latest kernel. Thomas will follow up with him.
- Nathan will work with Thomas to get some momentum on the project
EVIO-6
- Feature implementing dictionaries was not tested before so is being tested now
- Continued minor bug fixes
SOLID
- Carl will contact SoLID folks to find out when they have regular meetings and how we can connect so we can start attending occasionally.
JANA2
- Updated to get janadot feature working
- janadot is mechanism that allows call graph to be recorded along with timing of different algorithms
AI
- SciComp website being updated to include pages on:
- Using sciml nodes with GPUS (will add section on custom kernel)
- Using Jupyterhub (contacted Wes and has notes to start page)
- Hydra
- Code Jam on Friday with Thomas and Kishan (~14hrs)
- Code has been made more modular so different deployment options can be more streamlined
- Version 0.9
- More testing planned for this Friday followed by another week of development
- Expect paper writing to be done in Dec.
CODA/DAQ Support
- Bryan Moffit currently testing fixes to cmsgb implemented by Vardan
- New CODA version 3.10_arm
- Received message from Steve W. about errors on 32-bit systems with rcgui
- Temporary solution applied using the -nofx option which reduced graphics abilities
SRO
- Vardan went to JLab last week to work with Dave A. to get system setup in Indra lab using 8 fADCs
- Small difference in data format used in Indra firmware and format used in Hall-B caused initial crashes, but has now been resolved.
- Systems runs, but no hits are seen in the data stream. Ben may revert to older firmware version to test that. Ben and Dave A. will investigate
- Vardan has obtained access to ALICE code for SAMPA chip
- Vardan will contact Chris L. about him testing his Data Lake software with his software data source soon.
Offsite Computing
- Production of GlueX data offsite continues at PSC, IU, and NERSC
- Some issues with missing output files in few percent of jobs needs workaround
- NERSC multi-task jobs are running but supplementary script must be run by hand at JLab to move files to tape
- May be possible to move that functionality into SWIF2. Will need to meet with Chris to discuss.
- OSG test jobs have been trying to run at JLab.
- Some issues with files not making it to worker nodes.
- Significant progress though on getting this far. JLab SciComp/OSG team actively pushing across finish line.
- Thomas says: failure==progress
