Both [Tart Virtualization](https://github.com/cirruslabs/tart) and **Orchard Orchestration** (coming soon)
|
|
are licensed under [Fair Source 100 License](https://fair.io/). Usage on personal computers including personal workstations is royalty-free,
|
|
but organizations that exceed a certain number of server installations utilizing 100 CPU cores will be required to obtain a paid sponsorship.
|
|
|
|
??? note "Performance and Efficiency Cores"
|
|
The virtual CPU cores in Tart VMs do not differentiate between the high-performance and high-efficient cores
|
|
of the host CPU. Instead, Tart VMs automatically alternate between these types of cores depending on the workload
|
|
being executed within the virtual machines. As a result, both performance and energy-efficient cores of the host CPU
|
|
are treated equally in terms of licensing.
|
|
|
|
# Sponsorships
|
|
|
|
When an organization surpasses the 100 CPU cores limit, it is required to obtain a Gold Sponsorship, which costs \$1000 per month.
|
|
Upon reaching a limit of 500 CPU cores, a Platinum Sponsorship (\$5000 per month) will be required, and for organizations
|
|
that exceed 5000 CPU cores, a custom Diamond Sponsorship (\$1 per core per month) will be necessary.
|
|
|
|
If your organization is interested in purchasing one of the sponsorships, please email [licensing@cirruslabs.org](mailto:licensing@cirruslabs.org).
|
|
You can see a template of a sponsorship subscription agreement [here](assets/TartSponsorshipSubscriptionTemplate.pdf).
