RE: [Help-glpk] memory usage seems very high

[Meketon, Marc]

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.

Hmm... I successfully run that big.mod model under cygwin on a machine
having 2GB of RAM (unfortunately the url is broken now, so I cannot run
it once again).

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.)
