Hi all,
The work I am doing needs to store big attribute in a file. So I try to use
the following code !
==============
MPI_Comm comm = MPI_COMM_WORLD;
MPI_Info info = MPI_INFO_NULL;
MPI_Init(&argc, &argv);
fapid = H5Pcreate(H5P_FILE_ACCESS);
H5Pset_libver_bounds(fapid, H5F_LIBVER_LATEST, H5F_LIBVER_LATEST);
H5Pset_fapl_mpio(fapid, comm, info);
file_id = H5Fcreate("big_attribute.h5", H5F_ACC_TRUNC, H5P_DEFAULT, fapid);
.........
hid_t e_dpid;
e_dpid = H5Pcreate(H5P_DATASET_CREATE);
H5Pset_attr_phase_change (e_dpid, 0, 0);
dset_id = H5Dcreate(group_id, "/Step#0/Energy", H5T_IEEE_F32LE,
dset_space_id, H5P_DEFAULT, e_dpid, H5P_DEFAULT);
============
The compiling is OK, but running program always gives errors, such as:
============
HDF5-DIAG: Error detected in HDF5 (1.9.149) MPI-process 0:

heap
major: Heap
minor: Unable to insert object
#007: H5HFhuge.c line 383 in H5HF_huge_insert(): writing 'huge' object to

===========
It looks like we can't use H5Pset_libver_bounds and H5Pset_fapl_mpio at the
same time !
Anyone can give some help about this !
Cheers !
