The command-line user interface is a set of ancillary programs (commands) that enable you to do the following tasks:
Manage queues
Submit and delete jobs
Check job status
Suspend or enable queues and jobs
The grid engine system provides the following set of ancillary programs.
qacct – Extracts arbitrary accounting information from the cluster log file.
qalter – Changes the attributes of submitted but pending jobs.
qconf – Provides the user interface for cluster configuration and queue configuration.
qdel – Provides the means for a user, operator, or manager to send signals to jobs or to subsets thereof.
qlogin – Initiates a telnet or similar login session with automatic selection of a low-loaded, suitable host.
qmake – A replacement for the standard UNIX make facility. qmake extends make by its ability to distribute independent make steps across a cluster of suitable machines.
qmod – Enables the owner to suspend or enable a queue. All currently active processes that are associated with this queue are also signaled.
qmon – Provides an X Windows Motif command interface and monitoring facility.
qresub – Creates new jobs by copying running or pending jobs.
qrls – Releases jobs from holds that were previously assigned to them, for example, through qhold.
qrsh – Can be used for various purposes, such as the following:
To provide remote execution of interactive applications through the grid engine system. qrsh is comparable to the standard UNIX facility rsh.
To allow for the submission of batch jobs that, upon execution, support terminal I/O and terminal control. Terminal I/O includes standard output, standard error, and standard input.
To provide a submission client that remains active until the batch job finishes.
To allow for the grid engine software-controlled remote execution of the tasks of parallel jobs.
qselect – Prints a list of queue names corresponding to specified selection criteria. The output of qselect is usually sent to other grid engine system commands to apply actions on a selected set of queues.
qsh – Opens an interactive shell in an xterm on a lightly loaded host. Any kind of interactive jobs can be run in this shell.
qstat – Provides a status listing of all jobs and queues associated with the cluster.
qsub – The user interface for submitting batch jobs to the grid engine system.
qtcsh – A fully compatible replacement for the widely known and used UNIX C shell (csh) derivative, tcsh. qtcsh provides a command shell with the extension of transparently distributing execution of designated applications to suitable and lightly loaded hosts through grid engine software.
