Using Darshan tool
� Have you ever used Darshan tool? � If the answer is “I don’t know, probably not”, and you are using Shaheen 2 or Cori, then
maybe you have used it, as it is enabled automatic on Shaheen II and Cori.
� KAUST Supercomputing Laboratory (KSL) provides a framework to provide you easy access to performance data from Darshan: � Visit web page https://kaust-ksl.github.io/HArshaD/ for instructions. The framework is
supported on both Shaheen and Cori.

HArsaD I
� Connect to Shaheen with –X (for Windows/Linux) or –Y (for Mac)
� git clone https://github.com/KAUST-KSL/HArshaD.git
� Get the Darshan performance data from your last experiment, execute: � ./open_darshan.sh
� Get the Darshan performance data from the job id 65447, execute: � ./open_darshan.sh 65447
� Compare Darshan perfromance data from job id 65447 and 65448, execute: � ./compare_darshan 65447 65448 � You need extra tool, check the github link for instructions

HArshaD II - Comparison
� In case that you want to compare the execution of two applications, execute: � compare_darshan.sh job1_id job2_id � One PDF file, with the Darshan performance data of both executions, is created

Conclusions
� A suite of tools to use Darshan without knowing a lot of details was presented
� Explanations of how to read Darshan output
� Use the tools! https://kaust-ksl.github.io/HArshaD Provide feedback, we can add possible functionalities
