Lox: cool! I'm sure many people would like to have a go at your patched version.

My mman_win.h implementation resolves the problem also on Win32 :-P

Hi Diffid,

thanks for that. I've updated the post.

We've used (to make virtual visit of General Hospital of Ciudad Real) a render farm made with Oscar under linux stations (60-70 Pentium IV), but we don't need more than 1 GB of RAM (and the computers have exactly this size of memory). In fact, we can study buying more RAM for the computers. If the University of Castilla-La Mancha can support this project, this could be good! :-)

Your Blog says:

As it turns out, OSX (Orange uses an Apple XServe renderfarm) can only allocate 1.5GB per application at a time and other platforms seem to have similar problem.

Just to clarify "other platforms" comes down to M$ Windows:

Ton Quote from Orange Blog:

Now I can already see the Linuxers smirk! Yes indeed, doing renders on our Linux stations just went smooth and without problems. Linux starts with memory allocations somewhere in the lower half, and will easily address up to 3 GB or more.

I've committed a patch to the bf-committers list and on the patch tracker to implement the new memory mapped management system also on win32 platforms. It works like a charm so far, hope the dev team commit it soon on also on CVS.

If anyone wants to try it just download the source file here:

http://www.infosquid.net/repo/mman_win.h

Then put an include in intern\guardedalloc\intern\mallocn.c at line 44 and build the whole package ;-)

A new full fledged & patched windows build by me is coming soon here on BlenderNation.
