Large scale LP model

[A S]

Dear Pyomo Experts, 
Do you have any suggestion for solving large scale LP problems ? 

I am looking for open source solvers (not Gurobi or CPLEX) 

Is opensolver a good option ? if yes , do you have any toy example on how to use it ? 
Thanks in advance

Alireza,

hi! Given the benchmarks by Hans Mittelman (http://plato.asu.edu/bench.html) CLP is still the leading completely open-source alternative, followed by SCIP's SOPLEX. I have heard really good things about HiGHS recently (https://github.com/ERGO-Code/HiGHS) so you might want to give it a try.

Cheers,
