Can't write HDF5 file with vector bigger than 2^13

问题

I'm using C++ & HDF5 to write a file. But run into problems with it. This is the code I use:

void fileRead::writeFile(string name, const vector<double>* data) {
int dimn = data->size();

hsize_t dim[1] = {data->size()}; //-> 2^13!!!

hid_t sid = H5Pcreate(H5P_DATASET_CREATE);
hid_t didProp = H5Screate_simple(1,dim,NULL);
H5Pset_layout(sid, H5D_COMPACT);

hid_t did = H5Dcreate(fid, name.c_str(),H5T_IEEE_F64LE, didProp, H5P_DEFAULT, sid,H5P_DEFAULT);
H5Dwrite (did, H5T_NATIVE_DOUBLE, H5S_ALL, H5S_ALL, H5P_DEFAULT, &(data->at(0)));
H5Dclose(did);

H5Sclose(didProp);
H5Pclose(sid);
}

But this gives me this error message:

This happens for all vector sizes >= 2^13 (8192). Which is puzzeling me since reading in is no problem with bigger files and 2^13 is still a rather small number so something must be fishi with my code.

Any help would be appreatiated. yours magu_

From the documentation for the H5D_COMPACT parameter for H5Pset_layout:

Store raw data in the dataset object header in file. This should only be used for datasets with small amounts of raw data. The raw data size limit is 64K (65520 bytes). Attempting to create a dataset with raw data larger than this limit will cause the H5Dcreate call to fail.

So if your doubles are 8 bytes, you've run into that limit.

You need to use one of the other storage options, contiguous or chunked.
