Hello, guys,

I am doing a parsing job on the output of the sacct command and I know fields that could be specified to be outputted.
The difficulty I am facing is that I am in lack of detailed info about the fields. I need to do calculation on the fields so I need to understand what values they will be taking. For example, time field maybe in format like “YYYY:DDTHH:SS” or just “Unknown”.
Where can I find those detailed info? Is their any documentation about it?

Any help is greatly appreciated!

Best Regards,
Xiaojing

Which fields are you talking about. All of the fields seem to be well-documented in the sacct man page (https://slurm.schedmd.com/sacct.html). For example, you mention the time fields. For format for all the time fields seem to be rather well documented (See below) and you can use the SLURM_TIME_FORMAT environment variable to specify the format of some of those time fields.

Can you give a more specific example of a field you are having trouble parsing, and what programming language you are using to parse it? I had no problem parsing the date/time fields in Python. For example I wrote a Python routine that converted elapsed to seconds. I'd share the code with you, but I can't find it at the moment. I think it's on my personal computer instead of my work computer, which I'm using now.

From https://slurm.schedmd.com/sacct.html:

Elapsed time fields are presented as [days-]hours:minutes:seconds[.microseconds]. Only 'CPU' fields will ever have microseconds.


CPUTime
Time used (Elapsed time * CPU count) by a job or step in HH:MM:SS format.

CPUTimeRAW
Time used (Elapsed time * CPU count) by a job or step in cpu-seconds.


Elapsed
The jobs elapsed time.

The format of this fields output is as follows:

[DD-[HH:]]MM:SS


as defined by the following:

DD
days
hh
hours
mm
minutes
ss
seconds

End
Termination time of the job. Format output is, YYYY-MM-DDTHH:MM:SS, unless changed through the SLURM_TIME_FORMAT environment variable.

Reserved
How much wall clock time was used as reserved time for this job. This is derived from how long a job was waiting from eligible time to when it actually started. Format is the same as Elapsed.

ResvCPU
How many CPU seconds were used as reserved time for this job. Format is the same as Elapsed.

ResvCPURAW
How many CPU seconds were used as reserved time for this job. Format is in processor seconds.

Start
Initiation time of the job in the same format as End.

Submit
The time the job was submitted in the same format as End.

NOTE: If a job is requeued, the submit time is reset. To obtain the original submit time it is necessary to use the -D or --duplicate option to display all duplicate entries for a job.

Suspended
The amount of time a job or job step was suspended. Format is the same as Elapsed.

SystemCPU
The amount of system CPU time used by the job or job step. Format is the same as Elapsed.

NOTE: SystemCPU provides a measure of the task's parent process and does not include CPU time of child processes.

Timelimit
What the timelimit was/is for the job. Format is the same as Elapsed.

TimelimitRaw
What the timelimit was/is for the job. Format is in number of minutes.

TotalCPU
The sum of the SystemCPU and UserCPU time used by the job or job step. The total CPU time of the job may exceed the job's elapsed time for jobs that include multiple job steps. Format is the same as Elapsed.

NOTE: TotalCPU provides a measure of the task's parent process and does not include CPU time of child processes.


SLURM_TIME_FORMAT
Specify the format used to report time stamps. A value of standard, the default value, generates output in the form "year-month-dateThour:minute:second". A value of relative returns only "hour:minute:second" if the current day. For other dates in the current year it prints the "hour:minute" preceded by "Tomorr" (tomorrow), "Ystday" (yesterday), the name of the day for the coming week (e.g. "Mon", "Tue", etc.), otherwise the date (e.g. "25 Apr"). For other years it returns a date month and year without a time (e.g. "6 Jun 2012"). All of the time stamps use a 24 hour format.

A valid strftime() format can also be specified. For example, a value of "%a %T" will report the day of the week and a time stamp (e.g. "Mon 12:34:56").
