When should I use Flood Cloud

You should use Flood Cloud when time is critical and you have lots of simulations to undertake. It’s also useful when you don’t have enough software licences and/or hardware resources. Flood Cloud enables you to rapidly run all your simulations at once. 

​You can also use Flood Cloud to undertake more detailed analysis. With access to unlimited computing resources you can run many more simulations to help with model calibration, understand climate change impacts or improve designs.


What software can I run in Flood Cloud?

Flood Cloud allows you to run Jacobs’ Flood Modeller, BMT’s TUFLOW, US EPA’s SWMM and USACE’s HEC-RAS software.

In most cases, Flood Cloud supports the most recent versions of these solvers. In addition, it allows the user can select from a list of available versions for each solver type – for example, Flood Modeller simulations could be run on version 4.6 instead of 5.0 if required.

It is capable of running 1D, 2D and 1D-2D linked simulations, and can also integrate different software, such as Flood Modeller (1D)-TUFLOW (2D).

It provides CPU and GPU processing capabilities, allowing you to run TUFLOW HPC using your preferred solution. It will also be capable of running Flood Modeller GPU (coming soon).

Various modules are also provided, such as Flood Modeller’s 1D Urban Solver and TUFLOW’s Multiple Domain/Quadtree functionality. 

Contact us to find out whether we can support your model configuration.


What does Flood Cloud cost?

Flood Cloud is a pay as you go service. You are charged by the simulation minute.

Contact us for further information.


What's included in the price?

Everything! Computing infrastructure, any specific software licensing (if applicable) and technical support.  


Are simulations run on the CPU or GPU?

Both! For software which is capable of running on a GPU, such as TUFLOW HPC, you have the option to run it using CPU or GPU. Flood Cloud will use your current model configuration to decide which platform to run the simulations on.


What's the compute type used within Flood Cloud?

For our default compute type, we use compute optimized machines based on the latest generation Intel Scalable Processors (Cascade Lake), They offer up to 3.8 GHz sustained all-core turbo performance. These machine types offer much more computing power, run on a newer platform, and are generally more robust for compute-intensive workloads than standard machines. The machines have 4 CPUs and 16GB of memory.

For users wishing to run TUFLOW HPC on a GPU, Flood Cloud uses a NVIDIA Tesla V100 GPU, which is #1 on the TUFLOW benchmarking results.


Who is providing the underlying cloud infrastructure?

We currently use Google Cloud.


How do I access Flood Cloud?

First, install the Flood Cloud desktop application (see Downloads page). Contact our sales team to purchase credits. We will then provide you with a username and password. 

Within Flood Cloud, enter your login details, select which runs you wish to undertake, and press Run – it’s that simple! 


How many runs can I undertake at any one time?

Flood Cloud does not impose any restrictions. As long as you have credits in your account you can run as many simulations, at the same time, as you need to. 


How secure is Flood Cloud?

Flood Cloud is extremely secure, is end-to-end encrypted, and leverages Google’s state of the art cloud infrastructure. Flood Cloud protects cloud resources from unauthorized access, and from any un-intentional access to or destruction of user data.

Each Flood Cloud user has their own private cloud-based file storage area, not accessible to any other users. Each execution takes place in a private directory on a cloud computing node. This directory cannot be accessed by any other cloud user and is destroyed when the model execution is completed.

Google’s data centers are built with custom-designed servers, running our own operating system for security and performance. They use custom hardware running a custom hardened operating system and file system. Each of these systems has been optimized for security and performance. Since Google controls the entire hardware stack, they are able to quickly respond to any threats or weaknesses that may emerge.


What model files will be stored within the 'cloud'?

This is for you to decide. You have control over what is stored on the cloud. You have access to an amount of persistent cloud storage for input files and results you want to keep in the cloud. Results can be download and saved once the run has taken place. 


How much storage space is provided within Flood Cloud?

Flood Cloud provides 50GB of storage space per account. The storage space limit applies to model input data and not results. 


How will I know if there are any problems with the simulation?

Selected diagnostic information is streamed back to you in real-time in order to determine if a run is proceeding as expected or should be terminated and resubmitted to address an error. The returned data from a cloud simulation will contain all output and log files produced by the software.


Will I be able to stop a simulation once it has started?

Yes, you can terminate a run at any time.


Do all runs start simultaneously?

As soon as your model data files are uploaded, runs will start immediately. You have the option to run all the simulations simultaneously on different compute nodes or to queue your model simulations across multiple compute nodes.


What real-time updates will I receive during a simulation?

In the main Flood Cloud dashboard there are progress bars showing the status of each run that you have sent to Flood Cloud. In addition, in real time you can view the detailed runtime diagnostics for each run.
