Bladed Cloud

Features

• Bladed Cloud allows up to 300 parallel jobs per unique cloud environment.
• The cost is based entirely on compute hours used. Details of the cost/hour and available bundles are provided below.
• No inputs or results data is permanently stored in Bladed Cloud - data is saved temporarily in the cloud environment for each run, and the client machine controlling the batch downloads the data and deletes it from the cloud once the run has been completed.
• Bladed Cloud is primarily intended for wind file generation, and for running dtbladed calculations/simulations (it is not possible to run post-processing jobs).

Requirements & Restrictions

• A Base module license on a standalone or network dongle / cloud license server is required.
• A valid Bladed support agreement must be in place for Bladed Cloud to be used.
• Jobs targetting Bladed versions older than 4.3.0.85 cannot be run in Bladed Cloud.
• It is highly recommended that the latest version of Batch (currently v1.6, at March 2024) is used for running jobs in Bladed Cloud.
• Jobs that require special setup cannot be run in Bladed Cloud. For example, if the job has a controller that requires communication with another program on the computer that models a subsystem or needs to check for a special licence key, or a controller with runtime dependencies that cannot be satisfied by the cloud compute node.
• Bladed Cloud is available from data centers in Ireland, Germany or Japan. Unfortunately, the service is not available for users in China.

Security

The security of your data is of primary importance:

• Bladed Cloud uses an encrypted workflow to ensure that customer data is protected, both in storage and in transit.
• Any time that input data or results data is stored in the cloud, it is encrypted.
• Only the Batch instance that submitted the job can decrypt results data after it has been downloaded from the cloud environment.

Cost

Compute hours can either be purchased up-front in a Pre-Pay bundle (consisting of 10,000, 50,000 or 200,000 hours), or they can invoiced afterwards (Post-Pay). Pricing is available on request, and will be confirmed at the time of order.

For clarity, a "compute hour" refers to the compute resource required for running a single calculation. i.e. a 10,000 compute hour bundle would allow you to run e.g. 10,000 separate calculations each lasting 1 hour, or 20,000 separate calculations each lasting 30 minutes, etc.

Further Information

Further information about the practical use of the Bladed Cloud platform (including security considerations) can be found in the Batch Framework User Manual, which can be found in the Batch program folder, e.g. C:\Program Files (x86)\DNV\Batch 1.6 (search for "cloud" in the document).

Free Trial

If you would like to evaluate the Bladed Cloud platform, please contact us to arrange a free no-obligation trial:

• If desired, DNV can first provide a presentation and demo over Teams at a mutually convenient time, to demonstrate the features and usage of the platform.
• You will be required to review and sign a SaaS (Software as a Service) trial agreement.
• Access will then be provided to a trial Bladed Cloud environment.
• The free trial period will run for the duration agreed at the time of order, or until 1,000 compute hours have been used (whichever occurs first).

After the trial, you can choose to purchase a Pre-Pay bundle of compute hours, or use Bladed Cloud on a pay-as-you-go basis with Post-Pay invoicing.
