DFTICOMPUTEFORWARD... Debug Assertion Failed message

OP1 — Mon, 04 Aug 2008 21:59:20 GMT

[Edit: Actually the program fails for values of N which are a power of 2, and works otherwise... It fails for N=8, 16, 1024 etc..., and works for 9, 1023, 4097...]

I am using Intel Fortran 10.1, Intel MKL 8.1.1 and Visual Studio .NET 2003

I have a very simple program that uses the DFT commands (see example below). This programs triggers a "Debug Assertion Failed" message when I launch it (for a Debug configuration). The calculations are properly performed, and the results are good, but upon exiting the program (after the READ(*,*) statement) the error occurs. The same thing happens for a Release configuration.

Any idea?

Thanks in advance!!

ENDDO

Hi,

the problem you met looks like another issue was disscused in the Forum. Please follow the link: "__http://software.intel.com/en-us/forums//topic/60110"

Please try to use padding for your case - something like that:

ALLOCATE(TIME_DATA((N/2+1)*2))

Regards,

Gennady
