Introduction
Darshan is developed by Mathematics and Computer Science Division of Argonne National Laboratory to allow investigation and tuning of the I/O behaviour of complex HPC applications. It is open-source and available on github. Many Tutorials and hands-on excercises are available online.
Usage
Running program with Darshan instrumentation
First load the needed software module:
module load darshan-runtime
