fftw3 function crashes when running intel MKL

Yuri_F_ — Fri, 12 Oct 2012 20:35:01 GMT

Hi, I have very annoying problem. I installed Intel composer 2013 which I run with Ultimate Visual studio 2010. My fortran program uses fftw3 functions , for which Intel Visual Fortran has an appropriate wrapper. To build the application I have done the 2 following steps:

1. Put the path for fftw.h in the project->Properties->Fortran->Additional Include Directories to the location where the Intel composer 2013 is installed.

2. Enabled "UseIntel Math Kernel Library" by choosing "Sequential (/Qmkl:sequential)" oprion in the project->Properties->Fortran->libraries->.

I also increased the allocation of Stack Reserbve Size and Stack Commit Size to fit them to the program requirements.

After all that I have succesfully compiled and built the program

The problem shows up when the program is running, generating the following error when trying to execute fftw_execute_r2r(forward, in, in) function:

Unhandled exception at 0x00302827 in proba.exe: 0xC0000005: Access violation reading location 0x00000004.

When I run the same program on the Unix system, where the both program and fftw libriary were compiled with intel compiler everything is working perfect.

Many thanks for your help, Yuri

Hello Yuri, I am transferring this issue to the MKL forum. Someone on that forum should help you shortly. Regards, Annalee Intel Developer Support

Hi Yuri,

Hi Yuri, Accessing data at address 0x00000004 often aborts an application. Could you try to trace where this access took place? The address it printed may help if you have the application link map. One of reasons why the incorrect access may happen is missing check for NULL plan returned by fftw_plan_r2r. Additional information, maybe a piece of code and a build log, could help to identify the reason. Thanks Dima

Yuri,

Yuri, Could you check how the test will work when you link the example from command line? Is that 32 or 64 bit application?

I tried both 32 and 64 bit

I tried both 32 and 64 bit application with the same outcome. For 64 bit applicatio the following error is generated: Unhandled exception at 0x000000013fe228c4 in proba.exe: 0xC0000005: Access violation reading location 0x0000000000000040. Also the build log file is attached :

Can I upload the whole

Yuri_F_ — Mon, 15 Oct 2012 18:34:11 GMT

Can I upload the whole project, so you could exam it on your mashine? Many thanks, Yuri

yes, you can, but it would be

Gennady_F_Intel — Tue, 16 Oct 2012 02:39:33 GMT

yes, you can, but it would be much better if you prepare the smallest test case as you can for reproducing the problem on our side.

Ok, attached is a very simple

Yuri_F_ — Thu, 18 Oct 2012 03:41:34 GMT

Ok, attached is a very simple project which is supposed to perform fft transform Note that in order to run it on your machine you will need to change the include path for fftw. The program crashes when dfftw_execute_r2r routine is called Thank you for your help, Yuri

Yuri,

Dmitry_B_Intel — Thu, 18 Oct 2012 07:46:49 GMT

Yuri, Thank you for posting the example. MKL FFTW wrappers do not support 2D r2r. MKL conveys this information by returning null fftw plan. Thanks Dima
