[Darshan-users] technical report on Darshan 3.0.0 performance

[Shane Snyder]

Darshan users,

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.
