Hi,

I am trying to run 50 gurobi tasks simultaneously on cluster. This is what my batch file looks like:

#!/bin/bash
#SBATCH --partition common   
#SBATCH --mem=8G     # Memory limit for each tasks (in GBs)
#SBATCH --array=1-50
#SBATCH -o outfile_%j.out    # File to which STDOUT will be written
#SBATCH -e errfile_%j.err    # File to which STDERR will be written

python run.py  $SLURM_ARRAY_TASK_ID

Gurobi optimization is used in python file "run.py". However, I kept encountering this error "

gurobipy.GurobiError: Too many sessions, 5 active sessions for a baseline of 2"

How do I make it run 50 tasks simultaneously? I am using a free academic license (WLS).

Thanks!

  Hi,

  I will create a ticket for you.
  For the future: How do I obtain a free academic license for a cluster or a shared computer lab?
  The cluster admin can set up an appropriate license.

  Cheers, 
  David
