StoreHDF::write for 1D compile error

[Goon83]

Hi,
I am testing the HDF5 support in DASH. It reports compile error for 1D data at compile time.
Could you help to look at it ? See below for the code and error output.

Bests,
Bin

Code:

#include <libdash.h>
#include <iostream>

using dash::io::hdf5::hdf5_options;
using dash::io::hdf5::StoreHDF;

int main(int argc, char *argv[])
{
	dash::init(&argc, &argv);

	dash::Matrix<int, 1> *h5matrix = new dash::Matrix<int, 1>(dash::SizeSpec<1>(8));
	StoreHDF::write(*h5matrix, "testf.h5", "testg/testd");

	//2D works
	//dash::Matrix<int, 2> *h5matrix = new dash::Matrix<int, 2>(dash::SizeSpec<2>(8, 8));
	//StoreHDF::write(*h5matrix, "testf.h5", "testg/testd");

	dash::finalize();

	return EXIT_SUCCESS;
}

Looking into this right now. It seems that the 1D specialization of the TilePattern does not offer local_blockspec. Will try to come up with a patch soon.

[devreal]

@Goon83 Can you give the patch at #693 a try?

The 1D specialization of the TilePattern was missing the local_blockspec member function. I should note that the CSRPattern and the LoadBalancingPattern are missing that method, too, but I don't know enough about them to fix it immediately. I hope this helps though.

Hi devreal,
Thanks for working to resolve this issue. It compiles now without any error.

Bests,
Bin

hi @devreal
Another error comes up for the "StoreHDF::read" at compile time. It says that

"TeamSpec<[...], (default) long>' to 'const TeamSpec<[...], unsigned long>' for 3rd argument".

Looks wired that the "StoreHDF::read" works.

It might be the same as the previous error #688

BTW, my system is MacOS 10.14.6.

Bests,
Bin

Test code:

#include <libdash.h>
#include <iostream>

using dash::io::hdf5::hdf5_options;
using dash::io::hdf5::StoreHDF;

int main(int argc, char *argv[])
{
	dash::init(&argc, &argv);

	dash::Matrix<double, 1, unsigned long> *h5matrix = new dash::Matrix<double, 1, unsigned long>(dash::SizeSpec<1>(8));
	
         //This line works
         StoreHDF::write(*h5matrix, "testf.h5", "testg/testd1D");
	//This line fails
         StoreHDF::read(*h5matrix, "testf.h5", "testg/testd1D");

	dash::finalize();

	return EXIT_SUCCESS;
}

@Goon83 I think there is a problem with the explicit specification of the index type in your Matrix instance. This is certainly a bug in how we pass around this type to dependent templates. As a workaround, can you try removing the unsigned long from dash::Matrix<double, 1, unsigned long>?

@anindex can you take a look at this? We should include the cases brought up here in the DASH test suite (and extend it some more).

Hi @devreal,

Sure I will look into it tomorrow :)
