The Executable-Image version of GEMPACK runs only on Windows PCs. No Fortran compiler is required.

The Source-Code version of GEMPACK runs on Windows PCs or on other operating systems (eg, Linux). There are no size constraints, and models solve faster than with the Executable-Image version. A suitableFortran compiler is required. All Source-Code licences are multi-user (site).

See this table comparing different versions of GEMPACK.

RunDynam is a Windows program which greatly facilitates running simulations with recursive dynamic models.

Other choices

Some products are available in a Limited version, which will not solve models above a certain size. There are no size restrictions for Unlimited versions.

Site licences cover all employees at the main premises of an organization (more details here). Single-userlicences are also available for some products.

There are two payment schemes:

  • Under the single payment or permanent licence scheme your licence is valid forever, but technical support lasts 6 months only and you must pay to upgrade to new versions.
  • Some products are also offered under a subscription or annual payment scheme, which gives you all benefits (including continuing technical support and free upgrade to new versions). When we receive your annual payment, we send you a new licence, valid for one year.
