class	SimpleStorageService
	A storage service that provides direct access to some storage resources (e.g., one or more disks). An important (configurable) property of the storage service is SimpleStorageServiceProperty::BUFFER_SIZE (see documentation thereof), which defines the buffer size that the storage service uses. Specifically, when the storage service receives/sends data from/to the network, it does so in a loop over data "chunks", with pipelined network and disk I/O operations. The smaller the buffer size the more "fluid" the model, but the more time-consuming the simulation. A large buffer size, however, may lead to less realistic simulations. At the extreme, an infinite buffer size would correspond to fully sequential executions (first a network receive/send, and then a disk write/read). Setting the buffer size to "0" corresponds to a fully fluid model in which individual data chunk operations are not simulated, thus achieving both accuracy (unless one specifically wishes to study the effects of buffering) and quick simulation times. For now, setting the buffer size to "0" is not implemented. The default buffer size is 10 MiB (note that the user can always declare a disk with arbitrary bandwidth in the platform description XML).

Function Documentation

◆ compare_last_access()

bool wrench::compare_last_access	(	Block *	blk1,
		Block *	blk2
	)

Helper function to compare block by last access.

Parameters

blk1	: a block
blk2	: another block

Returns: true if blk1 was accessed before blk2, false otherwise

◆ generateHostUtilizationGraphLayout()

void wrench::generateHostUtilizationGraphLayout ( std::vector< WorkflowTaskExecutionInstance > & data )

Generates graph layout for host utilization and adds that information to the JSON object.

Searches for a possible gantt chart layout to represent host utilization. If a layout is found (no tasks overlap), then information about where to plot what is added to the JSON object. Note that this is a possible layout and does not reflect what task ran on what core specifically. For example, we may hav a task that was allocated 2-cores on a idle 4-core host. The task, when plotted on the gantt chart may end up in 1 of 3 positions (using cores 0 and 1, 1 and 2, or 2 and 3).

Parameters

data	JSON workflow execution data

Exceptions

std::runtime_error

◆ generateRandomUsername()

std::string wrench::generateRandomUsername ( unsigned long userid )

A method to generate a random username, so that generated workload traces look more realistic.

Parameters

userid numerical userid

Returns: a generated alpha userid

◆ isPointOnSegment()

bool wrench::isPointOnSegment	(	std::pair< unsigned long long, unsigned long long >	segment,
		unsigned long long	point
	)

Determines if a point lies on a line segment.

Parameters

segment	pair of start and end points that make up the line segment
point	point on a 1D plane

Returns: bool

◆ isSegmentOverlappingXAxis()

bool wrench::isSegmentOverlappingXAxis	(	std::pair< unsigned long long, unsigned long long >	segment1,
		std::pair< unsigned long long, unsigned long long >	segment2
	)

Determines if two line segments overlap along the x-axis and allows for a slight overlap.

Parameters

segment1	first segment
segment2	second segment

Returns: bool

◆ isSegmentOverlappingYAxis()

bool wrench::isSegmentOverlappingYAxis	(	std::pair< unsigned long long, unsigned long long >	segment1,
		std::pair< unsigned long long, unsigned long long >	segment2
	)

Determines if two line segments overlap along the y-axis using exact values.

Parameters

segment1	first segment
segment2	second segment

Returns: bool

◆ operator==() [1/2]

bool wrench::operator==	(	const BatchJobSet &	left,
		const BatchJobSet &	right
	)

Overloaded operator.

Parameters

left	left-hand side
right	right-hand side

Returns

◆ operator==() [2/2]

bool wrench::operator==	(	const BatchJobSetCoreLevel &	left,
		const BatchJobSetCoreLevel &	right
	)

Overloaded operator.

Parameters

left	left-hand side
right	right-hand side

Returns

◆ parseResourceSpec()

static std::tuple<std::string, unsigned long> wrench::parseResourceSpec ( const std::string & spec )

static

Helper static method to parse resource specifications to the <cores,ram> format.

Parameters

spec	specification string

Returns: a <cores, ram> tuple

Exceptions

std::invalid_argument

◆ searchForLayout()

bool wrench::searchForLayout	(	std::vector< WorkflowTaskExecutionInstance > &	data,
		std::size_t	index
	)

Searches for a possible host utilization gantt chart layout and updates the data to include what vertical position to plot each rectangle.

Recursive backtracking search for a valid gantt chart layout. This algorithm looks for a vertical position to place each task execution event such that it doesn't overlap with any other task.

Parameters

data	JSON workflow execution data
index	the index of the workflow execution data up to where we would like to check for a valid layout

Returns: bool

◆ to_json()

void wrench::to_json	(	nlohmann::json &	j,
		const WorkflowTaskExecutionInstance &	w
	)

Function called by the nlohmann::json constructor when a WorkflowTaskExecutionInstance is passed in as a parameter. This returns the JSON representation of a WorkflowTaskExecutionInstance. The name of this function is important and should not be changed as it is what nlohmann expects (hardcoded in there).

Parameters

j	reference to a JSON object
w	reference to a WorkflowTaskExecutionInstance
