[Darshan-users] Darshan 2.2.1 pre-release

[Phil Carns]

Hi all,

There is a pre-release version of Darshan 2.2.1 available at 
http://www.mcs.anl.gov/darshan/download/.  As with any pre-release, this 
2.2.1-pre1 version should not be used in production.  We may make 
changes before the final 2.2.1 release based on testing.  We would love 
to hear feedback from anyone who would like to try it out, though.

This release does a better job of tracking concurrent access from 
multi-threaded applications, which should be helpful for hybrid 
applications that use a combination of MPI and threading (or OpenMP).  
The other big change is significantly improved Cray support, although we 
intend to polish this further in upcoming releases.

thanks,
- the Darshan team
