PARALOOP::SCHEDULER::SGE - Scheduler object for use with SGE
PARALOOP::SCHEDULER::Scheduler
This scheduler is used for a cluster, equipped with the batch system SGE. I just hope it will work with other batch systems.
PARALOOP_Scheduler SGE PARALOOP_error_directory The name of the error directory PARALOOP_qsub_params String to pass to qsub PARALOOP_account String to pass to the -A switch of SGE
WhatParaloopScheduler my $msg=$obj->WhatParaloopScheduler()
Parameters my $msg=$obj->Parameters()
New my $obj = PARALOOP::Dummy->New(-params => $params, -log => $log);
IsSelfPossible If (&$obj->IsSelPossible()==1)...
Submit my $job_id = $obj->Submit();
RemTime my $rem_time = $obj->RemTime();
JobId my $job_id = $obj->JobId();
Usage: my $msg = PARALOOP::SCHEDULER::SGE::WhatParaloopScheduler() or my $msg = $obj->WhatParaloopScheduler() Function: Return some information (2 lines max) on the scheduler An object is NOT considered as a scheduler if this function is not implemented Arg: none ($self is ignored) Return: A message describing the plugin (1 or 2 lines)
Usage: my $msg = PARALOOP::SCHEDULER::SGE::Parameters() or my $msg = $obj->Parameters() Function: Return the list of allowed parameters for this scheduler If your scheduler defines some parameters, it is good pratice adding this function, to display those parameters when the --parameters switch of paraloop.pl is used. However, this is not mandatory Arg: none ($self is ignored) Return: A message describing the scheduler parameters (1 line / parameter)
Usage: &$obj->Submit() Function: Call a qsub. Arg : none Return: the job Id
Usage: my $job_id = $obj->JobId() Function: Ask the system for the job id The environment variable JOB_ID is returned Arg : none Return : the job Id
Usage: my $rem_time = &$obj->RemTime(); Function: Asks the system for the number of seconds remainig before a kill Arg: none Return: $rem_time = The number of seconds remaining (in fact subtract 5% for security)
Usage: If (&$obj->IsLaunched($job_id)==1)... Function: Check the presence of the job in the system Call qstat $job_id Arg: job_id: the job Id to check Return: 0 ==> The job is not known by the system 1 ==> The job is known (may be in different states: Run, Queue, etc)
Usage: $obj->KillJob($job_id); Function: Kill the job passed by parameter Call qdel $job_id Arg: job_id: the job Id to kill Return: none
Usage: if ($obj->IsSelfPossible()) ... Access: public (use New instead) function: return 1 if this scheduler accepts to submit himself, 0 if it doesn't Return: 0/1 Args: none globals: none
