The GDP is no longer supported by the Accessors Framework. This page exists as a historical reference.

https://gdp.cs.berkeley.edu/redmine/ describes the The Global Data Plane (GDP):

"The GDP is a middleware that provides a data-centric glue for swarm applications. The basic primitive is that of a secure single-writer append-only log stored on potentially untrusted distributed infrastructure. Logs natively support a publish-subscribe mode, making GDP a communication tool. At the same time, data in a GDP log can be stored for long-term in a fault-tolerant manner, thus making it an ideal tool for data-storage."

To use the GDP Acessors, you must have certain packages installed on your local machine.

The best way to do that is to run the script:

   accessors/web/gdp/adm/gdp-setup.sh

The idea is to use the GDP Java interface to insulate accessor development from changes to the GDP wire protocol. An alternative would be to write a GDP JavaScript Interface that uses the GDP wire protocol.

Cape Code and the GDP

$PTII/lib/gdp-X.Y-Z.jar - The Java/GDP interface jar file, which is included in the classpath by running (cd $PTII; ./configure)
- GDP Java Interface -> Update Ptolemy
$PTII/ptolemy/actor/lib/jjs/modules/gdp - The Cape Code Host implementation of the gdp accessor module.
- GDPHelper (JavaDoc) - Downloads and builds the gdp.
Tests
- $PTII/ptolemy/actor/lib/jjs/modules/gdp/test/GDPManager.tcl - Downloads and build the GDP, starts up the daemons and creates a few logs
- $PTII/ptolemy/actor/lib/jjs/modules/gdp/test/ | $PTII/ptolemy/actor/lib/jjs/modules/gdp/test/auto - Ptolemy models that test the GDP. To run these tests, install Ptolemy II, install the gdp libraries by running gdp/adm/gdp-setup.sh and then run $PTII/bin/capecode ptolemy/actor/lib/jjs/modules/gdp/test/auto/*.xml
- http://terra.eecs.berkeley.edu:8080/job/ptII/ - The PtII Jenkins nightly build which runs the above tests
- GDPTestGenerator - a model that is deployed on terra that generates regular test data.
