high-level editing tools for the documentation page | 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.

Converting CGNSTalk archive to Github Discussion Posts | Hope to be completed by the next meeting. No updates | |||||||||
Coupled fluid-structure standard addition | Proposal to standardize fluid-structure simulations submitted, no updates. | |||||||||
Discussion Topic | 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.
This work is a low priority for the majority of the past interested parties, this CPEX will be tabled

Status update on Accepted CPEX #0045
| The branch CPEX45_high_order has not been updated since Feb 25, 2020. An update from Koen Hillewaert on the status is needed. Regarding the two topics that I might want to say something on I have collected some input – feel free to use it (or not):
There is currently no one actively working on this, we will keep the project on the meeting agenda but we don’t expect any updates. | |||||||||
Open Discussion about backward compatibility issues | Discussion about backward compatibility issues discovered recently. Ansys, and others, has encountered backward compatibility issues with 4.3.0. All issues with backward compatibility will try to be addressed and fixed before the 4.4.0 release. All interested parties should either create an issue or contact the CGNS developers to ensure their issue has been addressed.
| |||||||||
Discussion Topic | 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.
| |||||||||
Status update on Accepted CPEX #0047 Proposed Data integration Points | 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) No new updates. Still in progress. | |||||||||
prioritization, review and attribution of JIRA bugs/issues | Next release 4.4.0, Kanban: https://github.com/orgs/CGNS/projects/2 Current status for Ansys: No issues that are urgent. 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. Scot Breitenfeld Can the APIs default to writing one dataset at a time if CGNS was not built with HDF5 1.14.0?
Scot Breitenfeld Is completing the option of using subfiling for CGNS. Perlmutter, write times: 65,536 ranks, benchmark_hdf5.c, 1 billion elements Independent, single-shared-failfile: 553.4 s Subfiling: 56.4 s Feature is scheduled for the next release, currently in the subfiling branch. |
