Re: [SOSlib-discuss] Model compiling on AIX now working and some questions

[Rainer M. <ra...@tb...>]

Hi Eric,

yes to both questions: an odeModel_t structure is only compiled once, 
and is reused for subsequent integrations (or for all 
integratorInstances which are based on this model!) and setVariableValue 
can be used as normal.

sensModel_t is independent from odeModel_t, and the corresponding 
functions are compiled when sensitivity is activated. I am not sure 
about recompilation of these, i.e. to which extend it is recognized that 
a specific sensitivity structure is already existing. It might be that 
this is still on the todo list and sensitivity is recompiled on every 
run. Let me know if this should be done sooner.

Thanks for all the AIX patches. We would probably like to contact to you 
before the next official release to check whether we made all changes 
correctly for AIX.

BTW, we are currently working on an internal compiler for the functions, 
but for now it only works on 32bit architectures and is not implemented 
in CVS yet.

Thanks,
Rainer
