We provide a range of simulation template which automate the analysis performed by users in several fields of civil and mechanical engineering. By editing a simple XML file, the user can quickly execute several scenarios and quickly obtain engineering information about the component or structure under investigation.

The pricing scheme is the simplest possible for a cloud HPC application. The base unit is the vCPU/Hour – so a unit which refers to the harware computing power allocated for every hour you use it. There are three standard models that differenciate the vCPU/Hour cost depending on the RAM allocated.

Beyond the vCPU/Hours computation, there are no other costs involved with the cloudHPC: so storage is completely free as well as data transfer (upload/download).

The user can choose between two types of instances: REG or SPOT. SPOT instances are excess power computing to which users may access with discount. While REG instances are exclusively used for the analysis, SPOT machines can be restarted at any time during the calculation (usually 2-3 times every 24 hours). After the machine reboots, the simulation restarts automatically from the last saved restart file. More information available in this tutorial.

Progressive discount

High use discounts are automatic discounts for running specific amounts of use in our cloud HPC platform every single month. Depeding on the montly turnover in terms of €uro spent on the platform, a progressive discount percentage is applied on the total amount. This percentage increases with the turnover on the platform for each moth and ranges from 0% to 30%.

The procedure to evaluate and to apply the discount is the following:

  • Evaluation of turnover of the current month
  • Given the amount the discount percentage is calculated from the following graph (from 0% to 30%)
  • Application of the discount percentage
Discount ranges applied on the montly platform turnover

On demand software licences

For specific software on demand an extra cost is applied to consider the licence cost of the software. These amounts are not considered in computing the turn-over for the progressing discount.

All the software installed on the platform are familiar also to our consultants and support is provided also as far as the case setup is involved in a proportional way to the simulations performed monthly on our platform.

How can I pay?

The free use of the platform does not involves payment and no payment data are required for this. Once the free use terminates, payment informations are mandatory and transaction can be either via debit/credit cards or via SEPA Direct Debit (if you or your company is EU based).

How long does the account generation take?

The account generation is generally quick and takes few minutes since the registration. Since every account has to be verified in order to avoid improper use of the cloudHPC platform, during weekends and bank holidays the account generation process may be slower.
