Dear all,

I’m on a mission to implement a BLAS “daxpy" routine (https://developer.apple.com/documentation/accelerate/1513298-cblas_daxpy?language=objc) in order to learn the basics of StarPU. I have a few questions I would like to ask:

1) When I partition the data automatically using the “starpu_matrix_filter_block”, is there a way to obtain the block sizes via the StarPU API?
2) Do I understand correctly, that when I use asynchronous interface, i.e. plan and submit data partition via StarPU routines, there is no way to iterate via the blocks using “starpu_data_get_nb_children” and “starpu_data_get_child” from the Basic API (http://starpu.gforge.inria.fr/doc/html/group__API__Data__Partition.html)?

Please see the C source code of my StarPU daxpy routine attached. Thank you and have a good Friday!

Best wishes,
Maksims
