Hi Barbara, Hi All,
Thank you for your answer. That's clear now about H5TBmake_table() call,
but...
H5Gcreate() in not a high level API, isn't it?
So why I cannot use it in parallel processes?
Maybe I'm just doing something wrong, so could you please provide me a
short example how to create a set of groups (each one is the process
number) running 4 parallel MPI processes? You can limit the example code
to the sequence of HDF5 calls only...
My current code works fine for just one process, but when I try it for 2
(or more) parallel processes the result file is corrupted:
plist_id = H5Pcreate(H5P_FILE_ACCESS);
H5Pset_fapl_mpio(plist_id, comm, info);
H5Pset_all_coll_metadata_ops( plist_id, true );
file_id = H5Fcreate(H5FILE_NAME, H5F_ACC_TRUNC, H5P_DEFAULT, plist_id);
H5Pclose(plist_id);
hid_t gr_id = H5Gcreate(file_id, std::to_string(procid).c_str(),
H5P_DEFAULT, H5P_DEFAULT, H5P_DEFAULT);
H5Gclose(gr_id);
H5Fclose(file_id);
Best regards,
Rafal

Hi Rafal,
No, the HDF5 High Level APIs are not supported in the parallel version of HDF5.

Subject: [Hdf-forum] high level API for parallel version of HDF5 library
Hi,
Can I use high level API function calls (H5TBmake_table(...)) in parallel
version of the HDF5 library?
There are no property list parameters for that function calls...
Regards,
Rafal
