No. The DIRSIG model has been developed with a significant amount of investment by Rochester Institute of Technology. The model represents an important piece of intellectual property that allows the University to obtain grants and contracts to fund student educations and research programs in a wide variety of topic areas. Forfeiting the monopoly on developing the model would jeopardize this advantage and the ability to maintain a healthy graduate program.
Furthermore, making the model open-source would most likely result in numerous corporate and organization variants of the model rather than one single, reference model. With a single version of the model, the computed results can be reproduced by anyone.
The DIRSIG software is distributed as binary executables only for the following supported architectures:
Sun Microsystems UltraSparc Servers and Workstations running Solaris 2.9+ (machine must be up-to-date with all patches)
Silicon Graphics (SGI) Servers and Workstations running IRIX 6.X
Intel Pentium and AMD Athlon Workstations running the Linux 2.4+ Kernel and Glibc 2.0+ (for example, RedHat 8+, Suse 8+, etc.).
Unfortunately, the answer is usually "No". We provide the software as a service to the community. The software is maintained and distributed free of charge and without any support contract in place to do so. The types of machines that we currently provide executables for are the machines we use on a daily basis and have access to. From time to time we do add another machine type, so always check back.
As a reminder, RIT provides the software as a service to the community. The software is maintained and distributed free of charge and without any support contract in place to do so. We attempt to distribute new versions quarterly or as dictated by bug fixes or new features being completed.
We maintain a mailing list of all current users. When a new release
of the software is available, we announce it via the mailing list.
If you do not think you are on this mailing list, send an email to
<dirsig@cis.rit.edu>. Also, always check the website
for new release announcements.
