Collaborative Computing Frameworks
Atlanta, GA, USA
Do you ever work with someone not in your office and wish that they could
look over your shoulder? Then you might be interested in the alpha
release of our collaboration environment.
The Collaborative Computing Frameworks (CCF) for Natural Sciences Research
is a collection of software tools that enable computer-based collaboration
by constructing a virtual work environment. CCF is an integrated
environment supporting shared X applications, multi-party communication
(audio and chat tools), annotation (via clearboard tool), data/file
sharing and (coming soon) computation sharing. Research methodology in
laboratory and instrument based sciences is increasingly dependent upon
computation, interaction, visualization, and data storage/retrieval. CCF
offers a solution for remote collaboration in this computer age.
We are looking for alpha testers for our collaborative computing
framework. CCF is an integrated environment supporting shared X
applications, multi-party communication, data/file sharing and (coming
soon) computation sharing.

We really want to know what you think of this package. Do you think it
might be useful to you? What did you like about the system? What did you
not like? What worked or didn't work? Did you have any trouble compiling
it? Did the supplied binaries run? Please let us know by sending mail to
ccf at mathcs.emory.edu, or fill out a comment on the download page:
Features of the alpha release:
* Remote users can share applications. All users will see
the application window; input (keyboard,mouse) may be
controlled by any one user at a time.
* Shared virtual desktop. Shared X applications appear in a single
virtual desktop which is WYSIWYS and has window manager functions.
* Audio conferencing tool. Multiuser, multiway internet telephone.
Several people can speak at once. Recording and playback available.
* Text based chat for when bandwidth is limited or audio hardware is
* Annotations of windows. Any shared window can be drawn upon with
"clearboard" tools. All users will see the markings.
* Shared data space. Users can import (upload) files and any user
can export (download). GUI based filespace manager (coming soon).
* Shared computation space (coming soon). Users can share their CPU
cycles with everyone in the group.
* CCF supplies an underlying transport layer for doing reliable
multicast independent of the MBONE. This library is suitable
for other groupware applications.
The current release to runs on IRIX 6.2, Sparc Solaris 5.5 and
higher, and Linux (2.0.xx and probably others, too). You must have
working pthreads to use CCF.
To retrieve the latest source distribution via anonymous ftp or the Web:
CCF is distributed as a compressed (GZIP) tar file
that unpacks as a single source tree (./CCF) containing
C and C++ source files and makefiles. The top-level Makefile
creates architecture specific bin and lib subdirectories
(e.g. bin/SunOS-5.6 and lib/IRIX-6.2).
CCF currently supports three platforms: Linux-2.0, IRIX-6.2, and
SunOS-5.5 and higher. The SunOS-5.6 version is the most thoroughly
Distributions containing only binaries are available as:
You may wish to try installing the binaries before attempting a source
build. Occasionally the binaries fail to execute properly due to
version inconsistencies with dynamically linked libraries.
Unpack the distribution using the GNU gtar utility:
tar xzvf ccfalpha-src-980402.tar.gz
zcat ccfalpha-src-980402.tar.gz | tar xvf
The latest source distribution file is about 1M compressed, unpacks
to 4M and expands by about 15-50M depending on your achitecture.
This can be trimmed in half by running "make clean" after building
to remove .o files.
The CCF Project at Emory University
CCF is a software system that supports collaborative,
distributed, computer-based problem solving in the natural
sciences, business, government, and in educational environments.
The goal is to evolve a virtual environment for distributed
computation that supports integrated human AV communication,
high performance heterogeneous computing and distributed data
management facilities. CCF is a research project at Emory University
involving the Math/Computer Science and Chemistry departments.
