Member Function Documentation

getStartTimeEstimates()

std::map< std::string, double > wrench::ConservativeBackfillingBatchScheduler::getStartTimeEstimates ( std::set< std::tuple< std::string, unsigned long, unsigned long, double >>  set_of_jobs )

overridevirtual

Method to obtain start time estimates.

Parameters

set_of_jobs

a set of job specs

Returns

map of estimates

Implements wrench::BatchScheduler.

processJobCompletion()

void wrench::ConservativeBackfillingBatchScheduler::processJobCompletion ( std::shared_ptr< BatchJob >  batch_job )

overridevirtual

Method to process a job completion.

Parameters

batch_job

the job that completed

Implements wrench::BatchScheduler.

processJobFailure()

void wrench::ConservativeBackfillingBatchScheduler::processJobFailure ( std::shared_ptr< BatchJob >  batch_job )

overridevirtual

Method to process a job failure.

Parameters

batch_job

the job that failed

Implements wrench::BatchScheduler.

processJobSubmission()

void wrench::ConservativeBackfillingBatchScheduler::processJobSubmission ( std::shared_ptr< BatchJob >  batch_job )

overridevirtual

Method to process a job submission.

Parameters

batch_job

the newly submitted BatchComputeService job

Implements wrench::BatchScheduler.

processJobTermination()

void wrench::ConservativeBackfillingBatchScheduler::processJobTermination ( std::shared_ptr< BatchJob >  batch_job )

overridevirtual

Method to process a job termination.

Parameters

batch_job

the job that was terminated

Implements wrench::BatchScheduler.

scheduleOnHosts()
