Hello,

we would like to generate and solve a large number of similar MIP-models in parallel on the different processor cores using Java. Can anybody provide a simple coding example?

Thank you and kind regards

Achim

  Hi Achim,

  There are multiple different packages for multi-processing in Java. I think it is best to ask in a Java dedicated forum for which of these package to use.

  Regarding Gurobi, you have to define a separate Environment for each MIP model you want to solve in paralell. It is not safe to solve models in parallel within the same Environment.

  Best regards, 
  Jaromił
