CERC — Environmental Software and Services

System requirements

Computer specifications

CERC's models are highly CPU-intensive. There are very few hard and fast rules for a PC specification to run CERC models, but the following points may be helpful.

  • CPU cores
    • Each run will use a single core
    • Ensure you have sufficient cores for the number of concurrent runs you anticipate
    • The maximum number of concurrent runs is determined by your licence. Please contact us if you want to change this.
    • Some users have found it useful to keep the number of concurrent runs less than or equal to the number of physical cores rather than the number of logical cores.
    • Fast CPU recommended
  • RAM
    • 2GB RAM per core used for model runs
    • Fast RAM recommended
  • Hard disk
    • Plenty of free disk space on the working drives. Typically the amount of space required per run will be tens of MBs, but can vary greatly depending on the output requested, from a few MBs to over a TB.
    • Keep at least 20% free disk space of the Windows drive for a healthy computer
    • Fast hard disk. Generally CPU & RAM speed is more important than hard disk speed.
  • Other
    • Only run on supported operating systems
    • Some products are supplied with a hardware key. The hardware key must be connected to a USB port (standard type A) which is available to the computer where the product is installed.
  • Operational considerations
    • Avoid running files over a network
    • Defragment drives used for model runs, including the Windows drive
    • Use a dedicated runs machine, and avoid doing other work at the same time
    • Use Run Manager to schedule runs
    • Turn off Windows screensaver
    • Run the model minimised

Supported versions

Software Supported versions3
ArcGIS4 Versions 10.1, 10.2, 10.3 and 10.4
Surfer Versions 10, 11, 12, 13 and 14
MapInfo Versions 11, 11.5, 12, 12.5, 15, 15.2 and 16

3 Use of third party software is only supported on those operating systems for which the manufacturer explicitly supports its use.

4 A patch is available from our user area to support ArcGIS 10.4. ArcGIS will also need the ESRI Spatial Analyst component to generate contours in ArcGIS.

Microsoft Office[top]

Current versions of CERC software (including the links to ArcGIS and MapInfo Professional) do not require Microsoft Office to be installed with the following exceptions.

Emission inventories

Users of ADMS-Urban, ADMS-Roads or ADMS-Airport who wish to directly edit an emissions inventory database using the Excel templates, as described in the User Guides, will require Microsoft Access and Excel to be installed. These must be versions supplied with or equivalent to Microsoft Office 2007 or 2010.

Access 2007 and 2010 users should note that each time they open an emissions inventory database in Access, they will be asked whether to upgrade it to the latest format. It is important to always answer No. If the database is upgraded to the latest format it cannot be used.

We do not support the direct editing of data in inventory databases using Access 2013 or later.

Surfer Automation and Slideshow Creator Utilities

These utilities are Microsoft Excel templates that use macros, so in order to use them you need to have a 32 bit version of Excel (2007 or later) installed.
