Hardware Recommendations

How to Choose Hardware for your Simulation

  • The number of cores are generally decided based on the model size, model fidelity and expense.

    • Model size: Cells, grid points, nodes, elements, degrees of freedom
    • Model fidelity: Time accurate, Single vs Double precision and Solver
    • Cost focus: Minimize dollar cost per solution
    • Cost-performance focus: Good balance between time to solution and computing cost
  • For example, CFD generally start with 75K - 100K cells per core

  • A good rule of thumb is to initially utilize a smaller number of cores to test your model before running the full intended core count

For CFD/FEA based simulations

  • Onyx
  • Emerald
  • Amber

For FEA codes with higher memory requirements

  • Melanite
  • Zinc
  • Topaz (for higher memory requirements)
