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/2003/2008/Vista/7/8, 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: 1 GB RAM per MC instance. CPU typically Intel Xeon 2.33 GHz or equivalent.
• operating system:Windows 2000/XP/2003/2008/Vista/7/8, Linux RedHat/CentOS/SUSE, Other Unix-like operating systems possible (e.g. HP-UX, Solaris), as long as there is a Sun JDK 1.7 available for the OS. A JMS provider such as JBoss 4 / 5 or activeMQ is required but is allowed to be on a separate server
• amount needed: it is recommened to have one machine per master-controllers

Central Database
This is the central data repository, linked to the master controller. We support Oracle 9, 10, 11. Oracle 12 is being tested. PostgreSQL 8.2 / 9.2 / 9.3, MS SQLServer 2000/2005/2008. 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, MsAccess, Derby or the open source Firebird db.

• advised internal memory and CPU: none, normal pc
• operating system: Windows 2000/XP/2003/2008/Vista/7/8, 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
