pilot_job_schedulera pilot job scheduler implementation (if nullptr then none is used)
compute_servicesa set of compute services available to run jobs (if {} then none is available)
storage_servicesa set of storage services available to the WMS (if {} then none is available)
network_proximity_servicesa set of network proximity services available to the WMS (if {} then none is available)
file_registry_servicea file registry services available to the WMS (if nullptr then none is available)
hostnamethe name of the host on which to run the WMS
suffixa string to append to the WMS process name (useful for debug output)
Exceptions
std::invalid_argument

Member Function Documentation

void wrench::WMS::addDynamicOptimization ( std::unique_ptr< DynamicOptimization optimization)

Add a dynamic optimization to the list of optimizations. Optimizations are executed in order of insertion.

Parameters
optimizationa dynamic optimization implementation
void wrench::WMS::addStaticOptimization ( std::unique_ptr< StaticOptimization optimization)

Parameters
optimizationa static optimization implementation
void wrench::WMS::addWorkflow ( Workflow workflow,
double  start_time = 0 
)

Assign a workflow to the WMS.

Parameters
workflowa workflow to execute
start_timethe simulated time when the WMS should start executed the workflow (0 if not specified)
Exceptions
std::invalid_argument

Set the simulation pointer member variable of the workflow so that the workflow tasks have access to it for creating SimulationTimestamps
