News / Management
  • June 6/7 : People visiting from U.Wisconsin's Center For High Throughput Computing to make a plan for how CASA (among others) is to use their Open-Source-Grid, the first likely application being VLASS data processing (this plan originates from AUI and is un-related to ongoing CNGI efforts).

  • Infrastructure
    • Several fixes were merged into master ~last couple of weeks. These PRs fix leaks that were hidden all over our infrastructure. The issues fixed explain ~10s GB of leaks, or >110 GB leaked memory for some ALMA pipeline datasets.
    • Our infrastructure (code/stdcasa, gcwrap/tools/StdCasa, gcwrap/tools) had/has issues everywhere, affecting virtually all tasks and tool functions. Examples: misuse of the Xerces API (transcode, etc.) in XML parsing (stdcasaXMLUtil), issues in the conversion between "casac record" and casacore::Record. issues in CASA tool wrappers in general, several tools frequently used in the pipeline severely affected: coordsys, image, regionmanager, imager, etc., issues in MSSelection, in imager and synthesisimager tools, casac.regionmanager, etc. See CAS-10226 for a list of recent (CAS-124XX) tickets.

        • Update the release conversion scripts
  • Unit
    • N/A
  • Verification
    • Currently working on gencal test
    • OSX hardware to support CASA 6 has arrived
