ippsSortAscend_32f_I goes into infinite loop

[thorsan]

Hi,

In my signal processing routine i sort a vector of 32f numbers using ippsSortAscend_32f_I(). But in some cases the vector is all zeros(or all equal numbers) and then the function call never returns. Ofcourse I could check for the vector to be non-zero, but I just feel like it should be reported. It is also the case if many numbers are the same, the routine is very slow.

Thanks,

Thor Andreas

Thanks for your report. Could you please provide a little bit more info on this? What is your IPP version, what is your test platform (processor, OS)? What is length of vector which cause the issue?

Regards,
Vladimir

Hi,

My IPP version is 5.3 ia32 and my CPU is U2500 @ 1.20 GHz running Windows XP. I have experienced this on another processor as well, but I dont remember the type of CPU.

The length of my vectors are in the range 1800-2300 samples.

Do you need any more information?

Thanks,

Thor Andreas

Thanks, yes, additional questions are

do you link IPP DLLs or static libraries (threaded/non threaded)?

Are you vectors aligned on data type size (4 bytes for Ipp32f)?

Hi,

Im linking using DLL's (ipps.lib) and I use ippsMalloc_32f allocate memory.

Thanks,
