Re: [SOSlib-devel] [SOSlib-discuss] Is sbmlsolver thread safe? (fwd)

Dear Liu Zhicong,

First I must say that unfortunately Andrew, our only Windows developer, is 
currently occupied in other projects. Personally I can not interpret  your 
error messages. I will try to contact Andrew about it and hope that he has some 
idea. In the meantime I will try my best to help you out:

Could you give some details on which functions of SOSlib you are using?

(Maybe you could also try to use the sourceforge CVS version of SOSlib and see 
whether your error still occurs - some bugs have been fixed there, see bug list 
at sourceforge). However, due to above situation, the windows directories are 
probably be up-to-date, in case you use this.)

In principle it is quite easy to run multiple integrations based on the same 
input model. You can create as many integrator instance as your system can 
manage, based on one ode model structure. SOSlib will actually handle memory 
errors and report according errors via its error management system and just 
return NULL instead of a new integrator Instance if the system is out of 
memory.

See the examples directory e.g. the file ChangingIntegratorInstance.c
(executable changeIntInst if you use the Makefile in this directory, don't know 
how that works on Windows) to learn about usage of SOSlib at the level of 
odeModel_t  and integratorInstance_t.

Using several integratorInstance_t instances created from one odeModel_t should 
be no problem and work without any memory loss.

Did this help you?

I am very sorry that we currently have no good support for Windows users. We 
would appreciate any contributions from this side. In general it would be great 
to get some feedback on problems and experiences you had with using SOSlib 
under Windows!

Rainer
