Release Note 2016

DHI Remote Simulation

Introduction

Welcome to DHI Remote Simulation Release 2016.

With this release, DHI offers access to remote simulation for corporate clients. The idea is that a user from a client computer is able to start a simulation remotely on a corporate hosted heavy duty computer. The remote simulation installation components are divided into a client component and a server component. Please consult the installation section of this Release Note, or the DHI Remote Simulation User Guide to get familiar with the solution.

System requirements

The recommended minimum system requirements are:

Operating systems Fully supported operating systems *
Windows 7 Professional Service Pack 1 (32 and 64 bit), Windows 8.1 Pro (64 bit), Windows 10 Pro (64 bit) and Windows Server 2012 R2 Standard (64 bit).

Non-supported but partially tested operating systems **
Windows 8.1 Pro (32 bit), Windows 10 Pro (32 bit) and Windows Server 2008 R2 Standard Service Pack 1 (64 bit).
Note that Release 2016 is the last release supporting 32 bit operating systems.
Processor x86 or x64, 2.2 GHz (or higher)
Memory (RAM) 2 GB (or higher)
Hard disk 40 GB (or higher)
Monitor SVGA, resolution 1024x768 in 16 bit colour
Graphics adapter 64 MB RAM (256 MB RAM or higher recommended), 24 bit true colour
File system NTFS
Software requirements .NET Framework 3.5 SP1 and .NET Framework 4.0 (Full Profile)

* Fully supported operating systems are systems that have been tested in accordance with MIKE's Quality Assurance procedures and where warranty and software maintenance agreement conditions apply.

** Non-supported but partially tested operating systems are systems, which are not officially supported by the MIKE software products. These operating systems have only undergone very limited testing for the purpose of MIKE software, but the software and key features are likely to work. Installation of MIKE software on a non-supported operating system is done so at the user's own risk. The MIKE software warranty and software maintenance agreement conditions do not apply for unsupported operating systems and DHI is under no obligation to provide assistance or troubleshooting for cases where the software is being used on a non-supported operating system.

Please note that single user installations are not allowed on server operating systems. Also, when running a fully supported operating system as a 'guest operating system' on a virtualisation platform, it is automatically downgraded to a non-supported operating system under the conditions provided above.

Installation

^ top

DHI remote simulation consists of a client part and a server part. The client part is by default always installed when installing any of the MIKE Zero based products and MIKE URBAN.

To install the server components, choose a custom installation and select the Remote Simulation Server Components during the installation process. The server components should not be installed on client PCs, unless it is the intention to also use the PC as a server environment. The setup programme automatically installs all necessary remote simulation files and folders on your PC.

Licence file and dongle

^ top

DHI Remote Simulation requires a network licence management scheme. To use DHI Remote Simulation in licenced mode, please follow these steps:

  1. A DHI Network License Manager must be installed and configured on a system in your network. Please refer to the relevant documentation for the DHI Network License Manager.
  2. During installation of MIKE Zero or MIKE URBAN, choose 'Network mode' and configure the installation to point to the machine hosting the DHI Network License Manager, or:
  3. After completed installation, start the DHI License Administration tool from the Windows Start menu, go to the 'license mode control' tab, and configure your system to run in network mode with the designated DHI Network License Manager.

Product invocation

^ top

Launch the DHI Remote Simulation from the Windows Start menu and select 'DHI Remote Simulation Console'. Starting DHI Remote Simulation without a valid licence will cause the programme to abort as demo mode is not supported.

When the 'DHI Remote Simulation Console' is running, you need to configure the connection to the server components of remote simulation. This requires the system administrator to have configured the server components. For details on setting up and configuring DHI Remote Simulation, consult the User Guide.

New features

^ top

Every new release of DHI Remote Simulation consists of new modules, new features or corrections to problems or significant inconsistencies discovered in previous releases. Please find short descriptions of the most significant news in Release 2016 below.

Module/type

New feature

User/Group management

The Remote Simulation framework now supports management of users and groups, allowing groups of users to share simulations while shielding these from other users. This feature is essential in multi-user environments where security is a concern.

Server file management

The Remote Simulation framework now supports management of files on the server, allowing users to perform basic file functions such as deletion or up- and download of individual setup or data files. This is as opposed to uploading an entire setup, thus facilitating multi-scenario runs.

Control of computational resources

Users of the Remote Simulation framework are now able to control the computational resources used for a simulation (i.e. how many nodes and cores). Availability of resources depend on server and simulation engine.

Basic Queue

The Remote Simulation framework now supports a basic queuing mechanism, allowing simulations to be uploaded and queued until the required computational resources are available.

Minor features and improvements

In addition a number of minor features and other improvements have been implemented, such as improved view of simulation properties.

Known defects and workarounds

^ top

Module/type

Known defect or workaround

Default file location

The model definition needs to use default file location for the output. Typically this is in a folder called '<model filename> - Result Files'.

You may be able to upload and start simulations without following this scheme, but the results may not be downloadable. This is especially important to ensure when using a coupled model setup. All simulations must use the default simulation folder.

'Save Output Files' in AUTOCAL

Using the 'Save Output Files' table in AUTOCAL, the Remote Simulation Client requires that a copy of the file exists before uploading the simulation to the server.

Specifcation of files in 'Save Output Files'

If res11read.exe is used in AUTOCAL to extract data from a res11 file, and the '-someres' or the '-compare' option is used in the setup file, then the files mentioned in these options must be specified in the 'Save Output Files' table.

Use of mpi adaptor

By default, the services installed as part of the server components use the system account of the server. Running DHI Remote Simulation using the mpi adaptor requires the application, data, and feature services to be changed to run in a domain account. The domain account needs to have access to the shared 'basedatastorageurl' (see table 4.4 in the manual).

Fixed issues

^ top

A service pack includes fixes to inconveniences and errors and minor modifications to the official release.
Please note that the service packs are accumulative, i.e. corrections and fixes released with a previous service pack are included in the newest service pack as well.
