Workflows template

Workflow are defined using a YAML manifest with the following structure:

name: "insert_workflow_name_here"
tasks:
# these are the tasks that will be executed sequentially to complete a trial (configure the system under tests with the parameters optimized by Akamas )
- name: "insert_here_name_of_task"
  # an operator specifies which type of task should be used
  operator: "insert_here_which_operator_to_use_for_the_task"
  # each operator accepts different arguments necessary to specify how it should behave
  arguments:
	...

with the following properties:

Name

Type

Value Restrictions

Required

Default

Description

name

string

yes

The name of the task.

operator

string

yes

The operator the task implements: the chosen operator affects available arguments.

critical

boolean

true

When set to true, task failure will determine workflow failure.

alwaysRun

boolean

false

When set to true, task will be executed regardless of workflow failure.

collectMetricsOnFailure

boolean

false

When set to true, failure of the task will not prevent metrics collection.

arguments

list

Determined by operator choice

yes

Arguments list required by operators to run.

The full list of Operators and related options is provided on the Workflow Operators pages.

Example

A workflow for the java-based renaissance benchmark application

name: renaissance-optimize

tasks:
- name: Configure Benchmark
  operator: FileConfigurator
  arguments:
    source:
      hostname: benchmark
      username: akamas

      path: launch_benchmark.sh.templ
    target:
      hostname: benchmark
      username: akamas
      password: akamas
      path: launch_benchmark.sh

- name: Launch Benchmark
  operator: Executor
  arguments:
    command: "bash launch_benchmark.sh"
    host:
      hostname: benchmark
      username: akamas
      password: akamas

- name: Parse Output
  operator: Executor
  arguments:
    command: "bash parse_output.sh"
    host:
      hostname: benchmark
      username: akamas
