SDK Crash - with debug options

Polar01 · ‎04-16-2013

Hi,

In order to debug my kernel, I try to compile my kernel with the following option :

-cl-mad-enable -g -s "E:\Proto\pure\pureLight\Kernels_Generated\kernel__ProductionRenderer.cl"

But when running, I got a crash !!!

Polar01 · ‎04-16-2013

Sorry, the crash is during the compilation !

Yuri_K_Intel · ‎04-16-2013

Hi Polar01, Could you please attach a minimal reproducer for this issue? Thanks, Yuri

Polar01 · ‎04-16-2013

Hi Yuri,

Sorry, but I have no time to develop such "reproducer", too much work here, sorry ;-)

Even if it should be very simple... it should be a simple kernel compilation with a few parameters.

In fact, maybe I can send you the kernel by email... there is nothing else special !

Yuri_K_Intel · ‎04-16-2013

You can use "Send Author A Message" link and attach a kernel to the message. Thanks, Yuri

Polar01 · ‎04-16-2013

Done ;-)

Thanks for your help

Yuri_K_Intel · ‎04-16-2013

Thanks. I was able to reproduce the behavior and I have submitted a ticket for this issue. I can't say anything regarding the root cause currently, but I just noticed that the file is very large. And as a possible work around you might try to extract to a separate file only the part you'd like to debug. Thanks, Yuri

Polar01 · ‎04-16-2013

Thanks a lot,

BTW, with the previous version of the SDK I was unable to debug this kernel !

When I put a breakpoint in the kernel arguments, it stop... but once entering the kernel... it is unable to "step over" :-(

Thx

it's seems I have the same pb with my configuration

I debug using CPU platform :

Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz

OpenCL 2.0 (Build 163)

when I add "-g" in kernel compilation options,

static char const* COMPILER_OPTIONS = "-g -I O:\\denoising\\ALGOS_OPENCL\\MainSrc\\SrcProcessing\\PrUv\\Algorithms\\MotionEstimator\\OPENCL\\kernel\\ -s O:\\denoising\\ALGOS_OPENCL\\MainSrc\\SrcProcessing\\PrUv\\Algorithms\\MotionEstimator\\OPENCL\\kernel\\prime.cl -cl-std=CL1.2";

I have a crash at the clBuildProgram line execution in VisualStudio 2013 and the message is :

Unhandled exception at 0x000007FEEAF266C9 (OclCpuBackEnd64.dll) in PreprocsVideoTest.exe: 0xC0000005: Access violation reading location 0x0000000000000010.

When I remove -g option,

static char const* COMPILER_OPTIONS = "-I O:\\denoising\\ALGOS_OPENCL\\MainSrc\\SrcProcessing\\PrUv\\Algorithms\\MotionEstimator\\OPENCL\\kernel\\ -s O:\\denoising\\ALGOS_OPENCL\\MainSrc\\SrcProcessing\\PrUv\\Algorithms\\MotionEstimator\\OPENCL\\kernel\\prime.cl -cl-std=CL1.2";

I have no more problem during execution but I suppose it is the reason the breakpoints set in a kernel are not seen.

At execution, I have a notification of lack of PDB files as exemple

'PreprocsVideoTest.exe' (Win32): Loaded 'C:\Windows\System32\ntdll.dll'. Cannot find or open the PDB file.

...

'PreprocsVideoTest.exe' (Win32): Loaded 'C:\Windows\System32\Intelopencl64_2_0.dll'. Module was built without symbols.
'PreprocsVideoTest.exe' (Win32): Unloaded 'C:\Windows\System32\Intelopencl64_2_0.dll'

and so on

Please to help me to explain what I have to do to allow breakpoints feature available in kernel source.

Hi Georges,

Which OS are you running on? Which version of the graphics driver? Could you provide a small reproducer with prime.cl included so I can try and reproduce the issue on my system?

Thanks!

Georges_J_ · ‎01-18-2016

thanks to answer my issue

I try to give informations you require :

OS is Windows 7 (details below)

Graphic driver is INTEL(HD)Graphics (details below); But, I can't update the driver and at the moment to install another one (I suppose) with

mediaserverstudioprofessional2015r6.exe

I receive failed message (detail of message "error 5 minimum requirements not met" in attached file):

Failed to process component: Graphics Driver

Click 'Continue' to ignore error and install other components or 'Cancel' to cancel installation and rollback changes.

Anyway, I can work without using graphic device opencl platform but only CPU platform (experimental CPU 2.0) as proposed on Windows environment to take VStudio facilities and Opencl debugging

And I have another Linux machine where I can use GPU and FPGA opencl targets

Note that my program works correctly without -g option on windows machine (targetted with CPU platform) and on Linux machine

Hi Georges,

Any chance you could upgrade to the following driver https://downloadcenter.intel.com/product/81502/Intel-HD-Graphics-2000-for-2nd-Generation-Intel-Core-Processors and try again?

Georges_J_ · ‎01-20-2016

Thanks a lot for your help

I would try to synthesis my situation.... (it's quite OK)

I used win64_152824.zip to update my driver (note win64_152824.exe file download failed); Now driver has been updated but it is quite the same (see below -- note previous install of win64_153628.4332.exe for exemple was rejected ---) :
In VS13, now, Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz platform is shown
but Intel(R) CPU on Experimental OpenCL 2.0 Platform (-device=CPU_2_0) platform has disappeared

Note that with my host code in execution in VS13 environment, it is strange that I detect 3 platforms ( 2 times the same) as shown below
But in VS13 menu, only one platform is shown ... and I can't no more build kernel session in CODE-BUILDER menu

Anyway the build is OK (kernels included) BUT without some PDB files;

extract of the build :
....
2> OpenCL Intel CPU device was found!
2> Device name: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
2> Device version: OpenCL 2.0 (Build 163)
2> Device vendor: Intel(R) Corporation
2> Device profile: FULL_PROFILE
2> Compilation started
2> Compilation done
2> Linking started
2> Linking done
2> Device build started
2> Device build done
2> Kernel <kernel_prime_estimationLoop> was successfully vectorized
2> Kernel <kernel_prime_init_temporalProjection> was successfully vectorized
2> Kernel <kernel_prime_sel_temporalProjection> was successfully vectorized
2> Kernel <kernel_prime_temporalProjection_fillProjectedPlane> was successfully vectorized
2> Done.
2> Build succeeded!
2>
....

1_
if I dont't add "-g" option in clBuildProgram, the execution runs without failure with 3rd platform selected
BUT if I add this "-g" option, I have again the break failure
AND in both cases, I can't use breakpoints in kernel
in this case, I can get informations from CODE-BUILDER/OpenCL Debugger menu

2_
if I add "-g" option in clBuildProgram with 1rst platform selected => it's OK
syntax is :
...
static char const* COMPILER_OPTIONS = "-g -s \"O:\\denoising\\ALGOS_OPENCL\\MainSrc\\SrcProcessing\\PrUv\\Algorithms\\MotionEstimator\\OPENCL\\kernel\\prime.cl\" -I O:\\denoising\\ALGOS_OPENCL\\MainSrc\\SrcProcessing\\PrUv\\Algorithms\\MotionEstimator\\OPENCL\\kernel\\";
...
error_num = clBuildProgram(* kernelProgram, num_devices , &device_id_list[DEVICE_IDX], COMPILER_OPTIONS , NULL, NULL);
...

AND breakpoints operate in kernel
in this case, no informations are available from CODE-BUILDER/OpenCL Debugger menu

So,
a) what explanation about platforms visibility ?
b) what's about PDB files issue ?
c) is there some means to mix breakpoints in kernels and host debugger features
