FAST.Farm
This benchmark focuses on FAST.Farm. FAST.Farm is an multiphysics engineering software designed to forecast the power performance and structural loads of wind turbines within a wind farm. It operates using OpenFAST and it is what allows our simulations to run in parallel.
For this benchmark we used the testcase ModAmb_3 that runs a simulation with 4 wind turbines that will be executed in multiple threads.
The original input files can be found here.
Software versions
The software versions used in this benchmark were the following:
| Component | Version |
|---|---|
| OpenMP | 201511 |
| FAST.Farm | v3.5.2 |
| gcc, g++, gfortran | 11.4.0 (Ubuntu 11.4.0-1ubuntu1~22.04) |
| kernel | 6.6.12-linuxkit |
Execution times comparison
Faster execution times are better. Units in seconds.Cost vs Time
The following plot shows how the execution times and costs vary with the number
of cores for each machine family.
For this specific simulation it seems the sweet spot is arround 8 or 16 VCPU's
, with c3 and c3d families being the most cost-effective.
