I have run many large models with this particular build that was compiled using Visual Studio 2008 C++ express.
Running Joey's model, I received no error messages - just the first 12 or so "generating Cx" statements, and then the command prompt. -Marc -----Original Message----- From: Andrew Makhorin [mailto:[email protected]] Sent: Wednesday, June 17, 2009 11:27 PM To: Meketon, Marc Cc: Joey Rios; [email protected] Subject: Re: [Help-glpk] memory usage seems very high > After glpsol issued the #8220;generating > CC.. #8221; line, I received the command prompt.

I'm not sure why glpsol does not work for you; there must be at least the message "xmalloc: no memory available". Most likely it is a bug in the C run-time library, *not* in glpk. Which compiler did you use to compile glpk? (For example, Borland C/C++ run-time library crashes at exit from the main program due to segmentation fault when the memory dynamically allocated by the program exceeds 64 Mb.)
