13 DECEMBER 2022

The Methods & Tools Special Interest Group met today from 4 pm till 5 pm Central European Time.

Agenda:

  • COBIA

Participants
AmsterCHEM (represented by Jasper van BATEN), Bryan Research & Engineering (represented by Michael HLAVINKA), Michel PONS (contractor to CO-LaN as Chief Technology Officer. Apologies received from U.S. Environmental Protection Agency (represented by Bill BARRETT)

Highlights

Methods & Tools SIG progressed the document on COBIA Threading models and worked especially on the diagram explaining the logic applied on COM-COBIA interoperability when threading is considered. The decision tree leading to the creation by COBIA (through COMBIA) of an instance of a COM-based PMC takes into account if and how COM has been initialized on the current thread and what is the threading model of the PMC. As a result only marshaling of calls and data by COM may be needed or marshaling by COBIA may be needed.

Next meeting of Methods & Tools SIG is scheduled for December 20, 2022.
