Platform For AI:Create and manage slots

Create a slot

1. Log on to the PAI console. Choose AI Acceleration > Dataset Accelerator in the left-side navigation pane.

2. Open the creation panel.

   • Method 1: On the Acceleration Slots tab, click Create Acceleration Slot.

   • Method 2: Create from instance details page.

     Note

     With this method, the Instance parameter is automatically set to current instance and cannot be changed.

     1. On the Acceleration Instances tab, click the target instance name to open its details page.

     2. On the Dataset Acceleration Slots tab, click Create Acceleration Slot.

3. Configure key parameters in the Create Acceleration Slot panel.

   Parameter	Description
   Instance	Existing acceleration instance.
   Bind Cloud Product	Cloud product matching the data source type configured for the acceleration instance. Object Storage Service (OSS) Read/Write Permissions: Read and write permissions for OSS. Options: Read-only or Read/Write. Select OSS Path: Storage folder for the dataset in OSS. General-purpose NAS, Extreme NAS Select File System: ID of an existing file system. File System Mount Target: Mount target to access the file system. File System Path: Existing storage path in NAS. Default: /.
   Maximum Capacity	Capacity for the acceleration slot. Must be greater than or equal to the dataset size. Configure based on the dataset size to accelerate.
   Mount Target	Configurable only for Alibaba Cloud Object Storage Service (OSS). Mount target attaches Dataset Accelerator to training cluster. Training tasks access acceleration slots through mount targets to read datasets with improved efficiency. Two configuration methods: Select Mount Target: Existing mount target. Create Mount Target: Configure parameters to create a mount target. Mount Target Type: Only VPC is supported. VPC Network: Existing VPC. If none available, click Create VPC to create one. vSwitch: Existing vSwitch. If none available, click Create vSwitch to create one. Note Dataset Accelerator supports only VPC mount targets. VPC mount target can be used by training clusters in the same VPC with different vSwitches. File system uses one IP address when adding a mount target. Select a vSwitch with many available private IP addresses. Mount target can be attached only by training clusters in the same VPC network.
   Enable Automatic Recycling	Turn on Enable Automatic Recycling to configure runtime or stop time for the acceleration slot.

4. Click Submit.

   System initializes the acceleration slot. Use the slot after its Status changes to Running.
