Member Function Documentation

void ebl::job_manager::initialize_other

(

const string &

other

)

[virtual]

Set the weights initialization for each job given corresponding jobs found in 'other' directory.

void ebl::job_manager::jobs_info

(

)

[protected, virtual]

Gather and print information about jobs, such as number of jobs running, number to run left, min/max running time.

list< string > * ebl::job_manager::list_job_dirs

(

const char *

conffname

)

[protected, virtual]

List all job directories found in conf's root directory and return that list. Caller is responsible for delete the list.

void ebl::job_manager::monitor

(

const char *

conffname

)

[virtual]

Monitor progress of jobs given existing directories and progress files ('progress' and 'finished').

void ebl::job_manager::prepare

(

bool

reset_progress = false

)

[virtual]

Prepare all jobs (create folders and copy/create files).

Parameters:

reset_progress

If true, ignore existing progress in target dir.

Reimplemented in ebl::mpijob_manager.

bool ebl::job_manager::read_metaconf	(	const char *	fname,
		const string *	tstamp = NULL,
		const char *	resume_name = NULL,
		bool	resumedir = false,
		bool	nomax = false,
		int	maxjobs = -1
	)		[virtual]

Read meta configuration.

Parameters:

tstamp	An optional timestamp to be used for the job's name instead of the current timestamp.
resume_name	If not null, resume the existing job with this name.
nomax	If true, lift the maximum concurrent jobs limit.
resumedif	If true, resume by reading existing job dirs, use global conf file otherwise.
maxjobs	Limit the number of concurrent jobs to maxjobs. If -1, defaut, use conf's 'meta_max_jobs' instead if defined.

Reimplemented in ebl::mpijob_manager.
