NAME

       nqs2pbs - convert NQS job scripts to PBS

SYNOPSIS

       nqs2pbs nqs_script [pbs_script]

DESCRIPTION

       This  utility  converts	a  existing NQS job script to work with PBS and NQS.  The existing script is copied and PBS directives, #PBS , are
       inserted prior to each NQS directive #QSUB or #@$ , in the original script.

       Certain NQS date specification and options are not supported by PBS.  A warning message will be displayed indicating the  problem  and  the
       line of the script on which it occurred.

       If  any	unrecognizable	NQS  directives  are encountered, an error message is displayed.  The new PBS script will be deleted if any errors
       occur.

OPERANDS

       nqs_script
	      Specifies the file name of the NQS script to convert.  This file is not changed.

       pbs_script
	      If specified, it is the name of the new PBS script.   If not specified, the new file name is nqs_script.new .

NOTES

       Converting NQS date specifications to the PBS form may result in a warning message and an incompleted converted date.  PBS does not support
       date  specifications  of  "today",  "tomorrow", or the name of the days of the week such as "Monday".  If any of these are encountered in a
       script, the PBS specification will contain only the time portion of the NQS specification, i.e. #PBS -a hhmm[.ss].   It is  suggested  that
       you specify the execution time on the qsub command line rather than in the script.

       Note that PBS will interpret a time specification without a date in the following way:

       -  If the time specified has not yet been reached, the job will become eligible to run at that time today.

       -  If the specified time has already passed when the job is submitted, the job will become eligible to run at that time tomorrow.

       PBS does not support time zone identifiers.  All times are taken as local time.

NAME

       pbs - general information on pbs

DESCRIPTION

       PBS stands for Portable Batch System.  It is a networked subsystem for submitting, monitoring, and controlling a work load of batch jobs on
       one or more systems.  More information about PBS is available in the PBS Users Guide.

       Batch means that the job will be scheduled for execution at a time chosen by the subsystem according to a defined policy and the availabil-
       ity  of	resources.   For  a normal batch job, the standard output and standard error of the job will be returned to files available to the
       user when the job is complete.	This differs from an interactive session where commands are executed when entered  via	the  terminal  and
       output  is  returned directly to the terminal.	PBS also supports an interactive batch mode where the input and output is connected to the
       user's terminal, but the scheduling of the job is still under control of the batch system.

       A job is typically a shell script and a set of attributes which provide resource and control information about the job.	 A  job  does  not
       have  to  be submitted on the system where it will run, tt can be submitted on any system with the PBS commands and access to the execution
       system, see qsub(1B).  Output will be returned to the system from which the job was submitted unless directed otherwise.

       Attributes offer control over when a job is eligible to be run, what happens to the output when it is completed and how the user  is  noti-
       fied  when  it  completes.   The attributes of the job may be specified on the command line or in the job script when the job is submitted.
       For information about job attributes, see qsub(1B) and pbs_job_attributes(7B).

       One important attribute is the resource list.  The list specifies the amount and type of resources needed by the job in order  to  execute.
       The  list  also	implies  a  hard upper limit on usage of those resources.  When the limit is reached, the job is terminated.  The types of
       resources available to a job vary with  the  system  architecture.   For  a  list  of  resources  supported  on	the  default  system,  see
       pbs_resources(7B).   There  are	man  pages  for  other	systems  types	as  well,  see	pbs_resources_aix4(7B), pbs_resources_fujitsu(7B),
       pbs_resources_irix5(7B), pbs_resources_solaris5(7B), pbs_resources_sp2(7B), pbs_resources_sunos4(7B), or pbs_resources_unicos8(7B).

       Once a job has been submitted, it may be monitored by use of the qstat(1B) command.  Two forms of output are available with the qstat  com-
       mand.   The  default form is the short display.	 Information about a job is limited to a single line.	Complete information about the job
       or jobs is available through qstat with the -f option.  Information will be given about all jobs in  the  system,  all  jobs  in  specified
       queues, or only specified jobs.

       When  displaying  status of jobs, you will see in which queue the job resides.  In PBS a queue is just a collection point for jobs, it does
       not imply any execution ordering.  That ordering is determined by a scheduling policy implemented by the system administration.

       Other commands of interest which have man pages of their own are:

       qalter  Alter a job's attributes.

       qdel    Delete a job.

       qhold   Place a hold on a job to keep it from being scheduled for running.

       qmove   Move a job to a different queue or server.

       qmsg    Append a message to the output of an executing job.

       qrerun  Terminate an executing job and return it to a queue.

       qrls    Remove a hold from a job.

       qselect Obtain a list of jobs that met certain criteria.

       qsig    Send a signal to an executing job.
