How to tell what the "peak memory" or "maximum memory needed" would be for a job based on the log?

[jolespin]

I (unfortunately) have a 48 hour limit for the job queues on my HPC. I have about 2 hours left until the job stops. I'd like to allocate only the amount of memory needed for the job but I can't tell that from the logs.

I'm using 128GB but that was just a guess.

Is there a way to estimate this from the logs?
