A question for Julia community.  
The problem I have has:  
\_nvars = 2483610  
\_ncons = 1269620  
\_total\_solve\_time = 91.625 sec  
Solver is AMPL+CPLEX.  
Is this a feasible problem for JuMP + GLPK? Anybody compared performances of JuMP + GLPK vs. GMPL+GLPK?  
Thanks!!  
Marco

This should be fine in JuMP. GLPK depends. But you can also use CPLEX via JuMP.

I suggest you just try it out and see what happens.

Thanks odow. I would like to try it with a free solver.
