What Are Sizes of the /cache Directories for Different Notebook Specifications in DevEnviron?

When creating a notebook instance, you can select CPUs or GPUs based on the data volume.

ModelArts mounts disks to /cache. You can use this directory to store temporary files. The /cache directory shares resources with the code directory. The directory size varies depending on resource specifications.

No disks can be mounted to /cache for CPUs. When only one GPU card is used, the /cache directory size is limited to 500 GB. If multiple GPUs cards are used, the /cache directory size is limited to 3 TB and calculated using the following formula: /cache directory size = Number of cards x 500 GB. For details, see Table 1.

Table 1 /cache directory sizes for different notebook specifications

Specification	/cache Directory Size
GPU, 0.25 cards	500 GB x 0.25
GPU, 0.5 cards	500 GB x 0.5
GPU, 1 card	500 GB
GPU, dual cards	500 GB x 2
GPU, four cards	500 GB x 4
GPU, eight cards	3 TB
CPU	N/A
