Cplant Usage
Cplant Usage Information
Cplant usage information is obtained from a global log file that is
written to each time a parallel jobs completes. The following
information is written to a single line of the log file for each
completed job:
- start date
- start time
- end date
- end time
- run time
- job size (number of nodes)
- user (Linux username)
- executable image (fully qualified pathname)
There are currently three utilities for parsing the log file and
compiling usage statistics:
cplant-usage.pl
- A Perl script that compiles and displays the following
information:
- total number of users each day
- total number of jobs each day
- total job time for each day
- average number of users for all days
- average number of jobs for all days
- average job time for all days
- average jobs size for all days
simultaneous-users.pl
- A Perl script that compiles and displays the maximum number of
simultaneous users at any given time during a day for all days.
Simultaneuous users are distinct users whose jobs were executing at
the same time.
simultaneous-jobs.pl
- A Perl script that compiles and displays the maximum number of
simultaneous jobs at any given time during a day for all days.
Simultaneous jobs are jobs that were executing that the same time,
possibly by one or more users.
Cplant Dedicated Time
The Cplant machine (Alaska) currently has dedicated time scheduled
