  Hi,

  To determine if Intel or AMD CPUs support the use of the quad parameter in Gurobi, you should check if the processors support quadruple precision computations. According to the Gurobi reference manual:

  - The `quad` parameter in Gurobi controls quad precision computation in the simplex algorithm.
  - Quad precision is only available on processors that support quadruple precision, such as common Intel processors. On other processors, the parameter has no effect.

  This means that to use the `quad` parameter effectively, your CPU must support quadruple precision. Most common Intel processors support this feature, but you should verify this for your specific CPU model. AMD processors may not support this feature uniformly, so it is important to check the specifications of your particular AMD CPU model to see if it supports quadruple precision computations.
