class accasim.utils.visualization_class.SystemUtilization(datasource, system_info, min_time=600, max_time=1800)

Bases: object

Using the matplotlib animation feature, this class will create a plot and update it during the simulation execution.

create_empty_map()

Creates the empty matplotlib figure.

job_draw(i)

Using the matplotlib animation the new jobs are draw into the plot. Besides previous jobs, axis info, legends are updated.

job_normalization(current_time, job)

Jobs are normalized in terms of the current visualization, setting as min and max the maximum width of the patch :param current_time: Current time of the simulation. :param job: Job object.

Returns:Return the min and max positions of the patch

load_new_jobs(current_time, running_jobs, _resources)

Loads new jobs into the jobs that are “running” in the plot. Checks first if it is already in the plot, if not it is added. The jobs are sorted in regards of the resource utilization. :param current_time: Current simulation time. :param running_jobs: list of running jobs. :param _resources:

modify_legend(ax, res, legend_size=10)

Modify the lenged of the resource type in regards of the jobs that use most the resources. Only a subset of jobs will be in the legend. By default 10.

Parameters:

• ax – Axis object
• res – Axis resource name
• legend_size – Default 10. Size of the legend.

next_color()

Moves for all available matplotlib colors

Returns:Return an specific color to represent a job.

set_colors()

Sets the available colors

start()

Initialize the plot

start_line_draw(current_time)

Draws the current time line and add the corresponding text :param current_time: Current simulation time

stop()

Stops the animation and close the figure.

update_finished_jobs(_finished_jobs)

Patches of completed jobs are removed from the chart :param _finished_jobs: Array list of job’s Id

update_running_job(_patches, _res, _used)

Updates the position of the patch in regards of the utilization of the resource

Parameters:

• _patches – Patch objects corresponding to a job.
• _res – Name of the resource type
• _used – How much the job uses of the resoure type.

update_ylabel(_ax, _res, _used)

Update the usage in the corresponding label of the resource type.

Parameters:

• _ax – Axis object
• _res – Axis resource name
• _used – Current usage of the resource type.

xlimit(current_time, ax=None)

Limit of the X Axis :param current_time: Current simulation time :param ax: None for all axis (there is one axis for each resource type) updates. Specify axis for a single update.
