Increase memory for GAMS

Hi there,

I need more memory for my code to run. I wonder how I can increase my memory. I had a lot of fixed variables and I used holdfixed option to increase memory but still I need more memory.

Thanks

It’s hard to give any specific advise, but I recommend that you use the command line option “profile=1” this will give you the memory (and time) requirement for each GAMS statement. With this you can see where the memory usage jumps and you can check why this is. If you run out of memory in the solver, the strategies are very different. Depending on model type you can do different things. You might want to read, e.g. http://www.gams.com/help/infocenter/topic/gams.doc.solver/cplex/index.html?cp=1_9_5_3#CPLEX_RUNNING_OUT_OF_MEMORY_FOR_MIP_PROBLEMS. This is for MIP problems with Cplex.

Hope this helps,
