an interesting/strange thing

yjyincj — Thu, 17 Sep 2009 10:59:56 GMT

I wrote a code that runns a variaty of allocate-deallocate arrays. When I run it in Win XP professional, it stops after it has run a while, saying insufficient virtual memory. However, it runs very well on Fedora 11 (x86). Is that because of the different memory management algorithm between two OS? Both computers have 2G ram.

Look in MSDN under Low Fragmentation Heap (or LFH). You may need to set the option to enable LFH.

Great! I have been wondering this for a long while. Yeah it should help with LFH. I found from msdn that LFH is enabled from windows vista. So there will be no problem to run on vista or Win7. Thanks.
