Many clients wish to know what the hardware and operating system requirements are for Delft-FEWS. On this page you can find a list of specifications. If you have any question about the list, or you do not see the operating system of your choice: please contact us. This list is not exhaustive.


Forecasting Shell Server
The forecasting shell server is the server for execution of forecast runs. It contains the modelling software and it's operation is controlled by the Master Controller

  • advised internal memory and CPU: Minimum 2 GB RAM and 1 one CPU core per FSS instance, CPU typically Intel Xeon 2.33 GHz or equivalent.
  • operating system: Windows 2000/XP/2003, Linux RedHat/CentOS/SUSE contains modelling software (incl. licenses), OS usually dependent on 3rd party modules and modelling software
  • amount needed: Minimum 2, more depends on computational load

Master Controller Server
The master controller organises task traffic and scheduling

  • advised internal memory and CPU: 800 MB RAM per MC instance. CPU typically Intel Xeon 2.33 GHz or equivalent.
  • operating system: Linux RedHat/CentOS/SUSE, Windows 2000/2003. Other Unix-like operating systems possible (e.g. HP-UX, Solaris), as long as there is a Sun JDK 1.5 (and 1.6 in the near future) available for the OS. JBoss 4.0.2 or Weblogic 8.1 SP3 (may be on a separate server)
  • amount needed: 1 or 2

Central Database
This is the central data repository, linked to the master controller. We support Oracle 10g (back to Oracle 9 supported), PostgreSQL 8.2, MS SQLServer 2000/2005, MS SQLServer 2008 under investigation (release of this db foreseen in autumn 2008). This list is not exhaustive, so contact us if you are thinking of using a different database or a different type.

  • advised internal memory and CPU: See Database vendor requirements. Typically 1 GB RAM per DB instance and CPU Intel Xeon 2.33 GHz or equivalent.
  • The database instance(s) can be a hosted on an existing database server or cluster.
  • uses 1 instance for each Master controller

Operator clients
The operator client (Gui) is the user end - thick client, multiplied by copying. The operator client uses a local datastore, usually MsAccess or the open source Firebird db.

  • advised internal memory and CPU: none, normal pc
  • operating system: Windows 2000/XP/2003/Windows 7, Linux RedHat/CentOS/SUSE
  • amount needed: as many as there are clients
  • possibilities to use under CITRIX available
  • using a mouse with scroll wheel is recommended

The webserver is an optional server that hosts and distributes the webpages generated by Delft-FEWS. Hardware requirements depend on the intended use.
