ConcurrentSettings

Create concurrent environments from a set of .prm files

Type: string
Default value: ""

This command-line only parameter allows you to specify a comma-separated list of .prm files that are used to set parameters for the different instances in a concurrent MIP run.

To give an example, you could create two .prm files with the following contents...

s0.prm:

MIPFocus 0

s1.prm:

MIPFocus 1

Issuing the command gurobi_cl ConcurrentSettings=s0.prm,s1.prm model.mps would invoke the concurrent MIP solver, using parameter setting MIPFocus=0 in one of the two concurrent solves and MIPFocus=1 in the other.

Note that if you want to run concurrent MIP on multiple machines, you must also set the ConcurrentMIPJobs parameter. The command for running distributed concurrent MIP using the two example files on two machines would be

> gurobi_cl ConcurrentMIPJobs=2 ConcurrentSettings=s0.prm,s1.prm model.mps

Note: Command-line only
