Differences between Unlimited Exe-image and Source-code GEMPACK
What are the main differences between the Source-Code and Unlimited Executable-Image
Versions of GEMPACK?
Both of these Versions can solve arbitrarily large models, limited only by the amount
of memory (RAM) on your computer.
The Unlimited Executable-Image Version uses the program GEMSIM to solve models.
With the Source-code Version it is usual to use TABLO-generated programs to solve
models. TABLO-generated programs can only be created with the Source-Code Version - they
cannot be created with Executable-Image Versions.
The main difference between these Versions is that GEMSIM takes noticeably longer to
solve models than a TABLO-generated program. This is especially true for larger models. A
comparison of solving times for some popular models shows the
difference.
A second major difference is that a suitable Fortran compiler is required for a
Source-Code Version but not for an Executable-Image Version.
The Source-Code Version offers more scope for re-distributing your model to others
(more information).
