Test for possible IppiConvValid bug

Hi,
 
I'm getting a -9 mem error with ippiConvValid_32f_C1R even though  my system has plenty of memory.
 
I allocated a 25GB with malloc just to make sure my program's memory allocation wasn't being limited by Windows.  No problems there.
 
Attached to this email is a compiled Windows x64 console app.  Everyone please download it and reply with the MAX size you can enter before you get a -9 err along with your system specs.  If you want to build it yourself, please go to my other post to download the VS project.  http://redfort-software.intel.com/en-us/forums/showthread.php?t=106382&o=a&s=lr
 
Hopefully there is a solution to this because it's really hampering me!
 
Best,
 
Ryan

Ryan,

Did you try to allocate more memory with a 'malloc' CRT function, for example 64GB and higher? Please take a look at
a test-application I created some time ago and attached to that post:

     http://redfort-software.intel.com/en-us/forums/showpost.php?p=189221

I'll take a look at your test-application.

Best regards,
Sergey

What about source codes of your test-application? At least simplified version that reproduces the problem
with ippiConvValid_xxx IPP function.

Hi Sergey,
 
I ran your mem test app with the CM3 line uncommented:
 
 __int64 _MEM_SIZE = ( 1073741824 * 64.0 ); // 64GB Recommended VM =  N/A  / 96GB
 
64-bit Windows platform
Allocating memory with 'malloc' CRT-function - 1D

Update,
 
I also tried my mem test app with IppiConvValid_16s_C1R, IppiConvValid_16u_C1R, and IppiConvValid_8u_C1R and the resutls are the same.
 
On my machine:
 
(Dual socket Intel Xeon E5645, 48GB DDR3) - 1.06 before I get -9 mem error.
  
On three other computers I've tried:
 
(Dual socket Xeon E5420, 16GB DDR2) -1.89.
(Dual socket Xeon E5420, 16GB DDR2) - 1.89.
(Dual socket i7, 12GB DDR2) - 1.89.

PS: That is really strange but it looks like older versions of WinRAR are not compatible with the newer versions.

Hi Ryan, This ia a short follow up regarding the error -9...

Quoting Ryan
...I'm getting a -9 mem error with ippiConvValid_32f_C1R even though  my system has plenty of memory.
 
I allocated a 25GB with malloc just to make sure my program's memory allocation wasn't being limited by Windows.  No problems there.
 
Attached to this email is a compiled Windows x64 console app. Everyone please download it and reply with the MAX size you can enter before you get a -9 err...


This is how it is declared:

     typedef enum
     {
         ...
         ippStsMemAllocErr           = -9,
         ...
     } IppStatus;

and I think the problem could be possibly related to limitation(s) of some IPP functions, including ippiConvValid_xxx. Your 64-bit system
allows to allocate up to 64GB of memory (!) and you've done two tests. These "magic" limitations were
disccused a couple of times on the IPP forum in the past. Unfortunately, there is no article that describes these limitations
in some functions of IPP library.

Best regards,
Sergey

Hi Sergey,
 
Yes I looked up that enum.  That's exactly my thinking.  I want to know why IppConvValid is having that problem.  For it to run out of memory on my system it would have to be doing a HUGE FFT.  What I find even stranger is that an i7 with 12gigs of DD2 memory can handle more than my Xeon with 48gigs of DD3.

OK!
 
I tried using IppConvFull instead of Valid.  I was able to enter 3.2 into my mem test program before I got the -9 error code.  So WHY, does ConvValid crap out at 1.06?
[cpp]//Allocate repImg
	Image repImg(srcImg.getSize().width + width_pad * 2, srcImg.getSize().height + height_pad * 2);

	//Repeat borders of imgSrc
	ippiCopyReplicateBorder_32f_C1R(srcImg.getPtr(), srcImg.getStepBytes(), srcImg.getSize(), repImg.getPtr(), repImg.getStepBytes(), repImg.getSize(), height_pad, height_pad);

	//Allocate convImg
	Image convImg(repImg.getSize().width + kerImg.getSize().width - 1, repImg.getSize().height + kerImg.getSize().height - 1);

	IppStatus status = ippiConvFull_32f_C1R(repImg.getPtr(), repImg.getStepBytes(), repImg.getSize(), kerImg.getPtr(), kerImg.getStepBytes(), kerImg.getSize(), convImg.getPtr(), convImg.getStepBytes());[/cpp]

Hi Ryan,

I'm sorry for some delay with my tests. I confirm that some internal problem with 'ippiConvValid_32f_C1R' exists. Please take a look at my results:

Please take a look at a screenshot:

'ippiConvValid_32f_C1R' uses lots of memory, especially when kernel size gets bigger, and it crashes
when it tries to allocate more than 1.65GB of memory.

It seems that getPtr( int x, int y ) is wrong, since it calculates y * size.width instead of y * stepBytes.
