I/O benchmark time reported by a 4,800-process IOR file per process
experiment that issued nearly 10 million distinct I/O operations on
NERSC's Edison Cray XC30 system. The experiment was repeated 15 times for each configuration to confirm that Darshan's impact onapplication performance is negligible.
Evaluating the New Modularized Version of Darshan on the Cray XC30

Darshan is a software tool designed and developed by a team of researchers at Argonne’s Mathematics and Computer Science (MCS) Division and widely used to gather I/O workload statistics from high-performance computing applications. Darshan’s original design goals were threefold: scalability on leadership-class computing systems, transparency to end users, and accuracy in the I/O characterization of applications. In 2015, the Darshan team – comprising Phil Carns, Shane Snyder, and Rob Ross – decided to add a fourth goal: modularization.
