- 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 2003 / 2008 / Vista / 7 / 8 / 10, 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
- a master-controller can use Windows and linux forecasting shells simultaneously
...
- advised internal memory and CPU: 1 GB RAM per MC instance. CPU typically Intel Xeon 2.33 GHz or equivalent.
- operating system: Windows 2003 / 2008 / Vista / 7 / 8 / 10, Linux RedHat / CentOS / SUSE, Other Unix-like operating systems possible (e.g. HP-UX, Solaris), as long as there is a JDK with the correct version 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 recommended to have one machine per master-controller.
