[svn-r5859] ./hdf5-devel/release_docs/RELEASE.txt
Purpose:
Merged from 1.4 branch
Description:
API tracing improvements
Platforms tested:
Linux (--disable-hsizet didn't work before my changes and still doesn't
work, but --enable-hsizet is fine).
Note: This checkin includes temporary code in H5FDmpiposix.c to turn
off GPFS byte range token prefetches on ASCI/Blue. Once the HDF5 API
supports the necessary prerequisite functionality this temporary code
can be migraged up above HDF5.
