is responsible for scheduling tasks in one or more workers. The workers may be in the same image as the runner, but are typically separate processes, sometimes on different hardware.
Tasks are instances of GtRrTask
Object subclass: #GtRrTask
instanceVariableNames: 'constraint result taskId taskTimeout retryStrategy executionData'
classVariableNames: ''
package: 'RemoteRunner-Tasks'
and are the unit of work handed out to a workers, Examples of tasks include:
Evaluating a script (GtRrScriptTask
GtRrTask subclass: #GtRrScriptTask
instanceVariableNames: 'script'
classVariableNames: ''
package: 'RemoteRunner-Tasks'
).
Synchronising code between the runner and workers (GtRrCodeSyncTask
GtRrTask subclass: #GtRrCodeSyncTask
instanceVariableNames: 'serializedChanges'
classVariableNames: ''
package: 'RemoteRunner-Runner-CodeSync'
).
Running checks, e.g. GtExample

s.
Accessing the default remote runner will start one or more workers on the local machine, based on the amount of free resources (CPU & RAM) (see GtRrResourceWorkerCountCalculator
GtRrWorkerCountCalculator subclass: #GtRrResourceWorkerCountCalculator
instanceVariableNames: 'minWorkers maxWorkers memorySizeMultiplier algorithm'
classVariableNames: 'DefaultAlgorithm DefaultMaxWorkers DefaultMemorySizeMultiplier DefaultMinWorkers'
package: 'RemoteRunner-Runner'
).
The default worker has code synchronisation enabled, allowing tasks to be run in the workers with the same code base as the runner, i.e. what is desired for a typical development environment.
The summary view of the runner shows the number of workers and current activity.
As an example, running a cript in a worker may be performed with:
GtRemoteRunner default submitJob:
(GtRrJob script: 'GtOsSystemInfo current currentProcessId')
