Is it possible to see variables in kernel in debug in Visual Studio?

nnain1 — Sun, 08 Mar 2020 04:55:06 GMT

As shown in the following image, trying to debug line by line of my source code.

Is it possible to see variable in kernal code? I can set breakpoint, but can't reach to that line in running the code.

Followed all instructions here for Windows using Visual Studio.

How can I debug variables in kernel code?

Hello Nyan,

Please confirm that you have edited the Registry Editor properly with proper type and value.

I just wanted to share some limitation with you, regarding windows debugger you can find them at this link.

It is possible to see the variables present in Kernel.

For Linux, you can directly use gdb-oneapi to debug ger to debug your code.

Here, I have attached the

As you can see below, I have

nnain1 — Sun, 15 Mar 2020 07:40:09 GMT

As you can see below, I have set at Registry Editor.

Then I made sure I have the followings.

Start Microsoft Visual Studio* Project

Run the x64 Native Tools Command Prompt for Microsoft Visual Studio* 2017 or Microsoft Visual Studio* 2019.

In the Microsoft Visual Studio terminal, set environment variables by running the following code:

set CL_CONFIG_USE_NATIVE_DEBUGGER=1

set SYCL_PROGRAM_BUILD_OPTIONS=-g -cl-opt-disable

Run the following command to start Microsoft Visual Studio:

devenv.exe

Build the Application

With Microsoft Visual Studio*, open a DPC++ project and add the sample application array-transform.cpp shipped with this release.

Go to Project > Properties > General and set Platform Toolset to Intel® oneAPI DPC++ Compiler.

Build the solution. In the Output window, verify that the build is successfull.

Setup Project Debugging Properties

Go to Project > Properties > Debugging and add the following value to the Environment field:

SYCL_DEVICE_TYPE=CPU

But I can't stop at line in kernel at A[index] = index[0] * 2 + index[1]; in the following code.

myQueue.submit([&](handler& cgh) {
        // The kernel write a, so get a write accessor on it
        auto A = a.get_access<access::mode::write>(cgh);
        // Enqueue a parallel kernel iterating on a N*M 2D iteration space
        cgh.parallel_for<class init_a>(range<2> {N, M}, [=](id<2> index) {
            A[index] = index[0] * 2 + index[1];
        });
 });

What could be issue?

Can you tell us the version

Can you try COMPILE instead

Jens_B_Intel — Sat, 04 Apr 2020 15:08:04 GMT

Can you try COMPILE instead of BUILD

set CL_CONFIG_USE_NATIVE_DEBUGGER=1

set SYCL_PROGRAM_COMPILE_OPTIONS=-g -cl-opt-disable

In addition to all the

In addition to all the settings discussed earlier, please, navigate Tools -> Options -> Debugging and unset Require Source Files.

Jens, thanks again for your help!
