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.

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

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.
