The ECOSIM SERVER requires a UNIX workstation with a high-resolution
graphics system (1280 by 1024), 256 simultaneous colors, i.e., an 8 bit
graphics frame buffer) with 32 MB RAM and, depending on the application,
1 GB of (data) disk space or more.
The ECOSIM SERVER will be supported on SUN Sparc architectures,
under SUN Solaris 2.5 or higher.
Support for alternative architectures and operating systems (HP UX,
IBM AIX, Intel Linux) can be arranged, but would require additional
resources not foreseen in the project.
In addition to the operating system, X Windows run-time libraries (usually
part of the basic systems software. Under SUN Solaris, the necessary libraries
and tools are available under /usr/openwin/lib and
Window Manager: Common Desktop Environment (CDE)
The system will also require a http demon (httpd)
for the client-server integration and Internet access.
For more information on http and setting up a local Web server,

The host of the ECOSIM SERVER will require Internet access
for some of its intended functionality.
To access remote computing and data resources, a minimum of 64Kb/s
will be required (e.g., through an ISDN phone line).
As external tools for data preparation, editing etc, the following tools
graphical editors and image conversion programs, including
xv, xpaint, giftrans
a standard GIS for geographical data capture and editing,
