[svn-r6148] ./hdf5-devel/src/H5FDmpiposix.c
Purpose:
Feature; Optimization
Description:
Clients pass `-1' or make their own #define for HDF5 functions
that take an optional object ID.
Blue's GPFS is slow for typical SAF restart dumps.
Solution:
Added a #define for H5I_INVALID_HID
Added GPFS-specific code to H5FDmpiposix.c that tells mmfsd to
forego byte range token prefetching. This code can be compiled
into the library by defining USE_GPFS_HINTS. The plan is to either
generalize this so it's detected during configure and turned
on/off at runtime, or to move it up into DSL/SAF with the new HDF5
functions to that return the low-level file handle.
Platforms tested:
SuSE Linux (arborea), gcc and mpich-1.2.4
SunOS (baldric), gcc
