Sage+Gurobi: Can I control how many processors vertex_coloring uses?
I am using Sage to color some graphs, using a 32-processor Linux server. I am using the vertex_coloring command, with Gurobi as the LP solver.
I've noticed that for graphs that take more than a few minutes, the program seems to eventually settle on using 16 processors. It would be nice if I could tell Sage (or Gurobi?) to allow more or fewer processors. Is this possible?
