Program Independent Jobs for a Generic Scheduler
7-23
testlocation = 'Plant30'
c.IndependentSubmitFcn = {@mysubmitfunc, time_limit, testlocation}
In this example, the submit function requires five arguments: the three defaults, along
with the numeric value of time_limit and the string value of testlocation. The
function's declaration line might look like this:
function mysubmitfunc(cluster, job, props, localtimeout, plant)
The following discussion focuses primarily on the minimum requirements of the submit
and decode functions.
This submit function has three main purposes:
• To identify the decode function that MATLAB workers run when they start
• To make information about job and task data locations available to the workers via
their decode function
• To instruct your scheduler how to start a MATLAB worker on the cluster for each
task of your job

Identify the Decode Function
The client’s submit function and the worker’s decode function work together as a pair.
Therefore, the submit function must identify its corresponding decode function. The
submit function does this by setting the environment variable MDCE_DECODE_FUNCTION.
The value of this variable is a string identifying the name of the decode function
on the path of the MATLAB worker. Neither the decode function itself nor its
name can be passed to the worker in a job or task property; the file must already
