How to Access GPU Instance

Once the instance is created, access the instance using the credential.

How to access Linux GPU Instance

After creating the instance, access it using SSH. The instance must have a Floating IP connected and TCP port 22 (SSH) allowed for the security group. Access the instance using the SSH client and the configured key pair.

For more information on connecting to SSH, see How to Access Linux Instance.

How to Access Windows GPU Instance

To access a Windows server, select a Windows instance to access from the NHN Cloud console. Click the Confirm Password button on the Access Instance tab of Instance Details to confirm the password configured in the Windows server.

Click the Connect button next to Confirm Password to download the .rdp file containing the configurations for accessing remote desktop and run it to access the Windows server. The ID of the Windows server is Administrator and the password is the one checked by the NHN Cloud console.

For more information on connecting to RDP, see How to Access Windows Instance.

Checking GPU Information

Access the instance, execute the nvidia-smi command, and check the GPU information.
