'Peak Memory' on daa2rma

In daa2rma, what is the meaning of the output line “Peak Memory: xxx of xxxG”
Is it RAM memory?
Mine says “140 of 375G”.
Is the second number (375G) the total amount of RAM on the machine? Because I know I’m supposed to have much more RAM than that on the AWS instance I’m using.
Is this number accurate for AWS instances?


The second number is the max amount of memory set for MEGAN. This value is set during installation of the program. If you want to change that setting, then you need to edit the text file MEGAN.vmoptions
