Your resource usage is determined by the cumulative amount of AUs, CPUs, and RAM, or a combination of the three. One AU is roughly equivalent to one CPU-hour, or to using one CPU core for one hour. For example, a 16-core instance running for one hour uses 16 AUs.


The default new user resource allocation is 168 AUs (Atmosphere Units), 16 CPUs, 128GB RAM. For more information on allocations for each provider, see Allocation Policies on the CyVerse website.

Instances are available on a first-come-first-served basis. Depending on Atmosphere's capacity, you may be unable to launch an instance even though you have sufficient allocation.

You can reuse your resources only after you have terminated or suspended an instance, and it has either changed to Suspended status or disappeared from your My Instances list.

A CPU hour is a CPU core used for one hour. For example, an instance that uses four CPU cores will consume four CPU hours for every hour that it is running. When your instance is stopped or paused, it will not contribute to the number of CPU hours your instances have used.

The default instance size is the smallest amount for the cloud provider, which is sufficient for the majority of uses. You may request more resources by submitting the request form, as outlined below.
