Liwering the amount of data written by System Overview

I am interested in measuring the power usage when solving a system of algebraic equations. However System Overview analyzer writes huge amounts of data in memory while working. Just reading a 4000x4000 matrix from a file that takes 5 seconds results in 19 GB of data in the result directory. Analyzing larger problems run out of RAM and crash.

 

I am mostly interested in the total power usage, not the usage in every millisecond. Is there a way to lower the amount of RAM needed by the analyzer?

You can lower the number of samples by increasing the sampling interval, which is defaulted to 1ms. You can also try disabling stack collection by creating a custom analysis type:
