Manual Reference Pages - SCRIPTINGSERVICEEXAMPLE (1)
- Example client script for the Scripting Service
is a small shell script providing an example of how to use the scripting
service PU and PE: it first creates a temporary directory with a name created
from the given unique ID. In this directory, an input directory is created
containing two files: an example input file "my-input.data" and a run
script "ssrun" (the run script is written by echo commands within
scriptingserviceexample). The input directory is archived by Tar/GZip and
provided to scriptingclient as input file. scriptingclient distributes the
input to a Scripting PE, which unpacks the archive and executes "ssrun".
"ssrun" gets the name of an output archive as its first argument; this archive
is created by the example script and contains an example output file
"my-output.data". The output archive is transferred back to the PU. Finally,
scriptingserviceexample dumps the content of "my-output.data".
can be taken as an example to do something more useful with the scripting
service: for example, simulation input could be packaged with a script actually
executing a simulation program on the input and archiving the results. Then,
the scripting service can be used to distribute a set of simulation runs to a
pool of processing nodes.
Important note on security: the scripting service does not include any
security features yet. That is, arbitrary scripts will be executed. Without
modifications (for example signatures), do NOT use it outside of a controlled
The following options are available:
Gives an unique identifier for the example run, for example: 1234.
