OneDNN DLL Init Memory Descriptor Crash

coco82 — Tue, 28 Jun 2022 09:46:33 GMT

Hi,

I'm trying to use the OneDNN dll from "C:\Program Files (x86)\Intel\oneAPI\dnnl\2022.1.0\cpu_iomp\bin".

I managed to call the first functions of creation of an engine "dnnl_engine_create(dnnl_engine_t *engine, dnnl_engine_kind_t kind, size_t index);" and to create a stream "dnnl_stream_create(dnnl_stream_t *stream, dnnl_engine_t engine, unsigned flags);".
However, when creating a memory descriptor with the function "dnnl_memory_desc_init_by_strides(dnnl_memory_desc_t *memory_desc, int ndims, const dnnl_dims_t dims,
dnnl_data_type_t data_type, const dnnl_dims_t strides);" my program crashes.

As for the values I send, here they are:
- ndims = 4
- dims = [1, 3, 13, 13]
- data_type = dnnl_f16 = 1
- strides = [507, 1, 39, 3]

If anyone has encountered this or similar problems with the OneDNN DLL, I would be really interested in a solution.
If you have any questions don't hesitate.
Thanks in advance

Hi,

Thank you for posting in Intel Communities.

Please can you answer the below questions:

1. Which oneAPI toolkit are you using in order to access oneDNN library? Is it Intel oneAPI Base Toolkit or Intel oneAPI DL Framework Developer Toolkit?

2. What is the version of that toolkit?

3. Please can you share the exact steps your tried in order so that we can reproduce the issue?

Thank You.

Hi,

Thanks for your answer, i totally forgot to reply because i found the solution for my problem.

The problem came from my use of the function dnnl_memory_desc_init_by_strides, I thought that the function returned the memory_desc and took care of reserving the memory according to the parameters however it is not the case, it is necessary to send in entry a ptr with a memory space sufficient to store the data.
