Connect to the head node through NICE DCV

NICE DCV is a remote visualization technology that enables users to securely connect to graphic-intensive 3D applications that are hosted on a remote high-performance server. For more information, see NICE DCV.

NICE DCV software is automatically installed on the head node when using base_os = alinux2, base_os = centos7, base_os = ubuntu1804 or base_os = ubuntu2004.

If the head node is an ARM instance, the NICE DCV software is automatically installed on it when using base_os = alinux2, base_os = centos7, or base_os = ubuntu1804.

To enable NICE DCV on the head node, dcv_settings must contain the name of a [dcv] section that has enable = master and base_os must be set to alinux2, centos7, ubuntu1804, or ubuntu2004. If the head node is an ARM instance, base_os must be set to alinux2, centos7, or ubuntu1804. This way, Amazon ParallelCluster sets the cluster configuration parameter shared_dir to the DCV server storage folder.

[cluster custom-cluster]
...
dcv_settings = custom-dcv
...
[dcv custom-dcv]
enable = master

For more information about NICE DCV configuration parameters, see dcv_settings. To connect to the NICE DCV session, use the pcluster dcv command.

Note

Support for NICE DCV on centos8 was removed in Amazon ParallelCluster version 2.10.4. Support for NICE DCV on centos8 was added in Amazon ParallelCluster version 2.10.0. Support for NICE DCV on Amazon Graviton-based instances was added in Amazon ParallelCluster version 2.9.0. Support for NICE DCV on alinux2 and ubuntu1804 was added in Amazon ParallelCluster version 2.6.0. Support for NICE DCV on centos7 was added in Amazon ParallelCluster version 2.5.0.

Note

NICE DCV is not supported on Amazon Graviton-based instances in Amazon ParallelCluster versions 2.8.0 and 2.8.1.

NICE DCV HTTPS certificate

NICE DCV automatically generates a self-signed certificate to secure traffic between the NICE DCV client and NICE DCV server.

To replace the default self-signed NICE DCV certificate with another certificate, first connect to the head node. Then, copy both the certificate and key to the /etc/dcv folder before running the pcluster dcv command.

For more information, see Changing the TLS certificate in the NICE DCV Administrator Guide.

Licensing NICE DCV

The NICE DCV server doesn't require a license server when running on Amazon EC2 instances. However, the NICE DCV server must periodically connect to an Amazon S3 bucket to determine if a valid license is available.

Amazon ParallelCluster automatically adds the required permissions to the ParallelClusterInstancePolicy. When using a custom IAM Instance Policy, use the permissions described in NICE DCV on Amazon EC2 in the NICE DCV Administrator Guide.
