CLmitedPrecisionRealType double malloc causes exception

Dziedzic, Peter

Hello community,

i have a problem. I use "CLmitedPrecisionRealType double malloc:" and this causes a exception on my Windows x64 System with 24GB memory.

vwnt.exe is just 1,6GB big. So it can grow till 4GB ( 32-Bit processes can use 4GB on a Win 64-Bit  OS).

My memory policy is:
ObjectMemory
installMemoryPolicy:
(MemoryPolicy new setDefaults;
preferredGrowthIncrement: (2 ** 24);
growthRetryDecrement: (2 ** 15);
freeMemoryUpperBound: (2 ** 25);
memoryUpperBound:4024000000
).

When i use malloc with a small number (e.g.: CLmitedPrecisionRealType double malloc: 100000)  then it works. but when i use it with a bigger number (e.g.: CLmitedPrecisionRealType double malloc: 1400000) then it  causes the exception.

I dont understand it cause i have a lot of free memory. Thanks for your help.

 

Mit freundlichen Grüßen - best regards,

Peter Dziedzic

Re: CLmitedPrecisionRealType double malloc causes exception

Hello,

 

have a look at this document concerning the memory limits of 32 bit applications running on 64 bit Windows.

 

http://msdn.microsoft.com/en-us/library/bb613473(v=VS.85).aspx

 

VW does not support IMAGE_FILE_LARGE_ADDRESS_AWARE, as far as I know, so the total memory is limited to 2 GB.

 

there are additional size limits, see doc/TechNotes/ImplementationLimits7x.pdf

Hello,

okay, I thought that the LARGEADDRESSAWARE-Flag is set in the vwnt.exe by default.
Now i set the flag with editbin.

thanks for your help.

Mit freundlichen Grüßen - best regards,

Re: CLmitedPrecisionRealType double malloc causes exception

In reply to this post by Holger Kleinsorgen-4
Hmmm, the 2GB limit has been fixed recently.  However, I think what
might be going on is that allocating a >10mb chunk with malloc: fails
because of fragmentation.  Can you reproduce the failure on a clean
image, or with an image that has not grown so large?  If, at the point
where the malloc: fails, you tried something like

   x := Array new: 3000000.

does it work?  Perhaps the first one does because you have enough
contiguous free memory, but does this work then?

   x := (1 to: sensibleNumber) collect: [:each | Array new: 3000000]

The idea is to set sensibleNumber to a value such that in theory there
would be enough space for the allocations.  If it fails well before it
gets to sensibleNumber, then it's likely that address space
fragmentation is a problem.

Andres.
