Tasks
Tasks¶
Each task is defined by a tool definition and is the smallest entity to process input.
Definition of a Task consists of a tool specification and relevant parameters:
{
"tool": "<tool>",
"parameters": {
"<param1>": "<value1>",
"<param2>": "<value2>",
[...]
}
}
A complete list of available tools and their parameters is available in Tools section.
Parallel Task Execution¶
Usually steps in the execution of a job depend on the previous step and will be executed sequentially by default, for example:
the 2nd pass of a H.264 encoding is dependent on the 1st pass
the processing of a file depends on the download to be completed
But some steps might not be depending on each other and can be executed in parallel such as:
the download of a file from source S2 does not depend on the successful download of a file from S1
no H.264 2nd pass depends on the result of another 2nd pass
By adding ‘|p’ to a tool name the execution engine will be made aware that the suffixed tool is not depending on the result of the previous tool.
