What Are Sizes of the /cache Directories for Different Resource Specifications in the Training Environment?

When creating a training job, you can select resources based on the size of the training job.

ModelArts mounts a disk to /cache. You can use this directory to store temporary files. The /cache directory shares resources with the code directory. The directory has different capacities for different resource specifications.

  • The eviction policy of Kubernetes disks is 90%. Therefore, the effective size of a disk is 90% of the cache directory capacity.
  • The local disks of BMSs are physical disks that have a fixed capacity. If you need to store a large amount of data, you can use SFS, which provides scalable storage.
