Common DSRC Commands and Tools

BC Project: FY10-06
Date of Policy: 23 Mar 2011
Last Updated: 02 Feb 2026 (see Revision Log)

This policy brings together common commands and tools initiated or developed by the Baseline Configuration Team. The commands are available in the default $PATH on all allocated HPCMP systems.

bcmodule

The bcmodule command works with modules on the HPC systems. The command executes like the standard module command, but has numerous improvements and new features. Since bcmodule does everything module does, users can think of it as a total replacement, though technically it is a "wrapper" which calls module. The bcmodule command makes compiler and MPI modulefile names more consistent, finds modules, searches for strings in modulefiles, and makes output easier to read. The bcmodule adds new features to the module command but does not replace it. For more details, click on additional information.

check_license

This command checks the status of HPCMP shared applications grouped into two distinct categories: Software License Buffer (SLB) applications and non-SLB applications. For more details, click on additional information.

cqstat

This command displays information about jobs in the batch queueing system. Fields displayed include job number and name, user name, subproject, cores/nodes requested, status, and queue, as well as several time settings. In addition, estimated job start time (when available) and relative job priority are displayed in the Waiting Jobs section. For more details, click on additional information.

node_use

This command displays memory-use and load-average information for all login nodes of the system on which it is executed. Information on memory-use and load average may help users choose a specific node on which they wish to do their interactive work. For more details, click on additional information.

qflag

The utility qflag collects information about the user and the user's jobs and sends a message about the reported problem without any need to leave the HPC system. For more details, click on additional information.

qhist

This command prints a full report on a running or completed batch job with an option to include chronological log file entries for the job from the batch queueing system. The command can also list all completed jobs for a given user over a specified number of days in the past.

qpeek

This batch job monitoring command returns the standard output (STDOUT) and standard error (STDERR) messages for any submitted batch job from the start of execution until the job run is complete.

qview

This command displays various reports about jobs in the batch queuing system. Among the attributes that are displayed are: job number, user name, queue name, job name, cores requested, wall time requested and used, and job status. The command can also display the reason jobs are in a Queued state, the maximum wall time remaining for running jobs, and a "load percentage" based on cores requested versus cores available. Finally, the reports can be filtered according to queue name, user name, status, and job number. For more details, click on additional information.

show_queues

This command displays current batch queuing system information. Attributes included in the queuing information are: queue name, maximum wall time, maximum cores, jobs (running and pending), cores (running and pending) and queue status. The command also displays node usage information (cores available, cores running, and cores free). For more details, click on additional information.

show_storage

This command produces a report on a user's file system quota limit and usage information for the storage areas in which the user owns data on the current system. For more details, click on additional information.

show_usage

This command produces two reports on the allocation and utilization of a user's subprojects. The default report provides this information for all subprojects of which the user is a member on the current system. The second report, produced by show_usage -s, provides information for all the user's subprojects on all systems at the local center. For more details, click on additional information.
