I am trying to measure utilization of the IO subsystem of a long running application with large number of threads on KNL. But data collection stops early due to the 500MB limit. I wanted to know is there a way I can increase the sampling rate, so that the application is profiled for the full duration.
Below is the command I am using and it looks like there is no knob for collect io to increase the sampling rate.
amplxe-cl -collect io -analyze-system -- application
