Detailed Description

An abstract class that defines a batch scheduler.

Constructor & Destructor Documentation

HomegrownBatchScheduler()

wrench::HomegrownBatchScheduler::HomegrownBatchScheduler ( BatchComputeService *  cs )

inlineexplicit

Constructor.

Parameters

cs	the batch compute service for which this scheduler is operating

Member Function Documentation

init()

void wrench::HomegrownBatchScheduler::init ( )

inlineoverridevirtual

Initialization method.

Virtual methods to override

Implements wrench::BatchScheduler.

processUnknownJobTermination()

void wrench::HomegrownBatchScheduler::processUnknownJobTermination ( std::string  job_id )

inlineoverridevirtual

Method to process a job termination when the job is already forgotten (useful for batsched)

Parameters

job_id

the id of the batch job that was terminated

Implements wrench::BatchScheduler.

scheduleOnHosts()

virtual std::map<std::string, std::tuple<unsigned long, double> > wrench::HomegrownBatchScheduler::scheduleOnHosts ( unsigned long  num_nodes, unsigned long  cores_per_node, double  ram_per_node  )

pure virtual

Virtual method to figure out on which actual resources a job could be scheduled right now.

Parameters

num_nodes	number of nodes
cores_per_node	number of cores per node
ram_per_node	amount of RAM

Returns

a host:<core,RAM> map

Implemented in wrench::FCFSBatchScheduler, wrench::CONSERVATIVEBFBatchScheduler, and wrench::CONSERVATIVEBFBatchSchedulerCoreLevel.
