Dear Contestant,
We decided to allow the use of two processor cores on the contestant VM (where you implement your solutions).
The updated VM is available on the download site. You received the download instructions in our e-mail from July 9th
Note that you need to enable hardware virtualization on your host machine for this to work. This is a BIOS setting and may be hidden somewhere where you would not expect it. On our evaluation machine, we found it under "system security".
You can enable two processors in your existing VM according to the attached screenshot. The VM needs to be shut down for applying the changes. Please do not change any other settings. Only settings that match the settings of the VM available for download are allowed in the final evaluation.
