Compute

Compute resource requests in Cortex follow the syntax and meaning of compute resources in Kubernetes.

For example:

- kind: model
  ...
  compute:
    cpu: "2"
    mem: "1Gi"

CPU and memory requests in Cortex correspond to compute resource requests in Kubernetes. In the example above, the training job will only be scheduled once 2 CPUs and 1Gi of memory are available, and the job will be guaranteed to have access to those resources throughout it's execution. In some cases, a Cortex compute resource request can be (or may default to) Null.

CPU

One unit of CPU corresponds to one virtual CPU on AWS. Fractional requests are allowed, and can be specified as a floating point number or via the "m" suffix (0.2 and 200m are equivalent).

Memory

One unit of memory is one byte. Memory can be expressed as an integer or by using one of these suffixes: K, M, G, T (or their power-of two counterparts: Ki, Mi, Gi, Ti). For example, the following values represent roughly the same memory: 128974848, 129e6, 129M, 123Mi.
