April 12, 2017 conference call

A new object model, the CAPE-OPEN Binary Interop Architecture (COBIA), has been proposed as a next step in the evolution of CAPE-OPEN. COBIA will include registration components, binary interoperability standards, and middleware that acts as a bridge between software components. Development of COBIA involves a number of tasks, grouped in phases, which can be performed incrementally. This memo is intended to describe these tasks, and provide an overview of the implementation process.

April 12, 2017 conference call

Post by colancto »

The Methods & Tools Special Interest Group from CO-LaN held a conference call on April 12, 2017.

On the agenda was to finalize appendix 1 of the COBIA Phase II contract that CO-LaN is entering with AmsterCHEM. A decision was reached regarding the software tool to be used as IDL parser generator.

Next we discussed how to address quad precision through CAPE-OPEN interfaces in COBIA. Nowadays quad precision is seldom used in process simulation software, at least to our knowledge. There have been here and there usage within a specific component but no export out of the component of values in quad precision. So there is no urgency to provide for quad precision through CAPE-OPEN interfaces. Still what matters is to give to COBIA an architecture that will let address quad precision in some future. Methods & Tools SIG provided its analysis of the possible solutions to CO-LaN Management Board for consideration.

Last some progress was made on a document developed within M&T SIG and meant to describe the changes induced by COBIA in the CAPE-OPEN specifications. VARIANTs are replaced by a CapeValue type and its equivalent for arrays. Seems necessary to look some more in consequences for thermodynamic methods such as GetSinglePhaseProp. Thermo SIG will address that as soon as possible.
