Cplex out of memory

I suspect there may be something unusual about your model, because I think your size should fit well in 16 Gb. I'd say the first things to try would be using names no and maybe barorder 3 in cplex.opt. If that does not help, you can also try using memoryemphasis 1, but that may slow down the solution considerably. As far as I can tell, the more threads are used, the more memory is needed, and so increasing the number of threads should not help. Also, just in case: make sure you are using 64-bit GAMS/Cplex.
