sacct MaxRSS ending with +

I used the command sacct --format="CPUTimeraw,MaxRSS" to get the MaxRSS of my slurm job.

However, the result looks like this:

MaxRSS
128340475+

What to make of this? Why is the MaxRSS ending with +? Which number is the final and can I get the result in Mb instead of kb?

Solution

  • The + sign indicates that the length of the decimal representation of the number is too large to hold in the colum. You can increase the column width

    sacct --format="CPUTimeraw,MaxRSS%20"

    the %20 part will tell sacct to set the MaxRSS column width to 20 chars.

    As for getting the results in MB, I do not think Slurm offers that but with numfmt you can get a more human-redable version of it:

    sacct --format="CPUTimeraw,MaxRSS%30" | numfmt --header=2 --field=2  --from=auto --to=iec --invalid=ignore
