TIBCO GridServer® 7.1.0

# Binary-level Integration

PDriver, or the Parametric Job Driver, is a Driver that executes existing command-line programs as a parallel processing Service using the GridServer environment without using the API, taking full advantage of the parallelism and fault tolerance of GridServer.

PDriver achieves parallelism by running the same program on Engines several times with different parameters. A script is used to define how these parameters change. For example, a distributed search mechanism using the `grep` command could conduct a brute-force search of a network-attached file system, with each task in the Service being given a different directory or piece of the file system to search.

PDriver uses its scripting language, PDS, to define Services. PDS scripts can also set options for a PDriver Service, such as remote logging and exit code checking.

For more information about PDriver, see the TIBCO GridServer® Developer's Guide.
