Virtual and bare metal cores

Within the platform you can choose to run your cases either on the economical virtual cores or on the fastest state-of-the-art bare metal cores.

Virtual core costs


Most economical

  • 4 GB of memory per virtual core
  • Using one hyper-threaded full bare metal core
  • Average saving potential compared to a bare metal core: ~27%

Bare Metal Core costs


Most powerful

  • 8 GB of memory per bare metal core
  • Running on two virtual cores
  • Roughly 41% faster than virtual CPUs

Virtual vs bare metal core example

Let's make a sample calculation

Let's take a SimpleFoam flow case with around 4 million cells and compare virtual and bare metal cores. The case takes about 5000 iterations to converge. We run it on 8 virtual cores and 8 bare metal cores.
On the virtual cores, the case takes 3460 seconds, whereas the bare metal cores finish the job in 2440 seconds.
This will result in the following times and costs:

Resource CPUh per h Time CPUh used Sum USD
8 vCPUs 8 3460 7.7 0.92
8 bare metal CPUs 16 2440 10.8 1.30
