Darshan Release Change Log
--------------------------
Darshan-3.3
=============
* add wrappers for preadv, preadv2, pwritev, and pwritev2 (improves profiling
of ompio)
* improve error handling in command line parsers to make incomplete logs more
Darshan-3.3.0-pre1
=============
* added first version of PyDarshan, which provides interfaces for
accessing Darshan log file data from Python applications
* added AutoPerf modules for tracking MPI communication usage (APMPI) and
for tracking Cray XC performance counters (APXC)
* modified Lustre module to use 'fgetxattr' rather than 'ioctl' for
querying stripe info to avoid known bug in Lustre that could cause
application crashes
* fixed bug leading to potential deadlock when reducing shared file records
for MPI applications (known to affect mvapich2)
* fixed bug preventing usage of Darshan's non-MPI mode in builds that use
MPI compilers
* boosted Darshan's default internal memory allocation from 2 MiB to 4 MiB
* added wrappers for openat, preadv, preadv2, pwritev, and pwritev2 (improves
profiling of ompio)
* various bug fixes to enable usage of HDF5 modules in non-MPI applications
* fixed HDF5 module bug leading to warnings on stdout for applications using
non-MPIIO VFD for HDF5
* fixed HDF5 module bug leading to potentially incorrect values in H5D module
common access counters
* added new H5D record value to indicate corresponding H5F record ID, to
allow easier mapping of HDF5 datasets to files they belong to
* improved error handling in command line parsers to make incomplete logs more
obvious to users
* fixed bug leading to incorrect internal timing information at Darshan
shutdown time
* fixed bug causing negative Darshan counter values from being plotted when
using the darshan-job-summary tool
Darshan-3.2.1
=============
