[Optimizer] SkyPilot does not list GPU instances when large num of CPUs are requested

[romilbhardwaj]

I want to get a 192+ CPU instance through SkyPilot, do not care if it comes with GPU(s). --cpus 192+ does not yield any instance:

$ sky launch --cpus 192+
I 05-26 10:13:04 optimizer.py:1264] No resource satisfying <Cloud>(cpus=150+) on [GCP, AWS, Kubernetes].
sky.exceptions.ResourcesUnavailableError: Catalog and kubernetes cluster does not contain any instances satisfying the request:
Task<name=sky-cmd>(run=<empty>)
  resources: <Cloud>(cpus=150+).

To fix: relax or change the resource requirements.

Hint: sky show-gpus to list available accelerators.
      sky check to check the enabled clouds.

Even though gcp a3-highgpu-8g and AWS p5.48xlarge satisfy this request:

$ sky launch --gpus H100:8
