As part of our transition to the new modularized version of Darshan
(3.0.0), we have published a technical report evaluating its
performance on Edison, a production Cray XC30 system at NERSC. This
technical report primarily serves as validation that Darshan’s
performance remains suitable for full-time deployment on production
HPC systems, but it also provides some additional background that
may be useful in understanding the design changes made to Darshan’s
runtime library and log file format. Our results indicate that
Darshan’s new design is still lightweight enough to run full-time on
production systems with little to no impact on the performance of
instrumented applications.<br>
