Discussion topics
Item | Presenter | Notes |
---|---|---|
Approve 2021/3/29 minutes. | @Scot Breitenfeld | post last meeting’s minutes to CGNS webpage. Approved |
high-level editing tools for the documentation page | @Marc Poinot @Christopher Rumsey | Help needed to divide the remaining tasks: https://github.com/CGNS/cgns.github.io/projects/1 The documentation goes into the source using Doxygen. This work uses the “Doxygen” branch. Examples are given for cg_open and cg_version. The aliases used for repeated variable descriptions are in src/Doxygen/Doxygen.config. We need volunteers to help with translating the remaining APIs to Doxygen.
Still in progress. |
Converting CGNSTalk archive to Github Discussion Posts | @Scot Breitenfeld | Started converting the CGNSTalk archive to GitHub discussion posts. Still in progress, the plan is to have it finished by the next meeting. |
Discussion Topic | @ZJ Wang | Short discussion on past AMR CPEX (0008) and whether AMR should be revisited as a feature supported CGNS. Some groups may be already using CGNS with AMR, but not known for certain. The need for AMR support in CGNS is unknown. @Vicky Moschou @Tobias Leicht @ZJ Wang to discuss progressing CPEX 0008. |
Status update on Accepted CPEX #0045 | @Koen Hillewaert | The branch CPEX45_high_order has not been updated since Feb 25, 2020. An update from @Koen Hillewaert on the status is needed. @Scot Breitenfeld will follow up with @Koen Hillewaert to find out the status. @Scot Breitenfeld will email committee an update, and @Tobias Leicht may take over the discussion if needed. @Koen Hillewaert will start working on it soon, and @Tobias Leicht has offered to help when, or if needed. |
Discussion Topic | @Mickael PHILIT | Proposal to have Monitoring numerical probes description to the standard. Some groups may already use CGNS to do that, but there is a need to have a shared approach. Committee needs to review the proposal and provide feedback. @Scot Breitenfeld to send out a reminder. https://cgnsorg.atlassian.net/browse/CGNS-272 Some feedback received. Did not have time to improve the proposal. Will take feed back from meeting and present an updated CPEX at the next meeting. |
Status update on Accepted CPEX #0047 Proposed Data integration Points | @Mickael PHILIT | Working on the new website before creating a new development branch to prevent duplicating efforts. Started prototyping with python and C and will push a branch on GitHub in the upcoming weeks. (The “C” branch is a slow work in progress) Is now in a branch on GitHub. |
Status of Future CPEX 0046 | @Thomas Hauser | There is no one available to move forward with the CPEX. @Scot Breitenfeld will remove it from the discussion topics. NO UPDATES To be removed from the meeting notes. |
Status of Future CPEX 0044 | @Koen Hillewaert | The current focus is on finishing and implementing CPEX 45. Tabling CPEX 0044 for now. NO UPDATES ON HOLD To be removed from the meeting notes. |
prioritization, review and attribution of JIRA bugs/issues | @Tony Garratt @David Gutzwiller | Next release 4.4.0, Kanban:
General Kanban Board: ISSUE CARRIED OVER: Platform proposals Do we test both 32bit (legacy) and 64bit API? It's a minor point, but it would a good idea to add 32bit to at least one Linux and Windows NEW (June 2021). We need to add Intel OneAPI compilers to the list of supported compilers (note: OneAPI C/C++ compiler is very different to existing legacy one) Bug list: A priority of bugs to fix in next release #1 Crucial to Ansys. Although most HPC is Linux, project set-up often was done on Windows and import/export/sharing of mesh/solution done on Windows, while most runs performed on Linux clusters
#4 #5 #6
@Scot Breitenfeld is working on updating the Multi-dataset APIs in CGNS to use the new array-based API and is testing CGNS with the new HDF5 subfiling feature. |
A reminder that new CPEXs will have to address backward/forward compatibility before being voted on.
