64 ビットバイナリの作成に関して調べていて /LARGEADDRESSAWARE を見つけたのでメモ．
/LARGEADDRESSAWARE (大きいアドレスの処理)
これを有効にすると 64 ビット環境で 2 GB を超えるメモリを利用できるみたい．
プロジェクトの「プロパティ」－「構成プロパティ」－「リンカ」－「システム」－「大きいサイズのアドレス」
次の様なコードで動作を確認．
#include <iostream> #include "memstat.hxx" #include "gettickc.hxx" int _tmain (int argc, TCHAR* argv[]) { u_32 free_M = 0 ; { MemoryStatus ms ; std::tout << long(ms.GetPhysFree()/1024/1024) << std::endl ; free_M = u_32(ms.GetPhysFree ()/1024/1024) ; } { std::vector <void*> memAry(1024,(void*)NULL) ; u_32 index =0 ; u_32 allocTotal = 0 ; u_32 allocSize = free_M/2 ; u_32 ngCount = 0 ; for (index=0 ; index<free_M && ngCount<10 ; ) { if (allocSize == 0) { break ; } void* pAlloc = calloc(allocSize,1024*1024) ; if (pAlloc != NULL) { allocTotal += allocSize ; } else { allocSize /= 2 ; ngCount++ ; continue ; } MemoryStatus ms ; std::tout << allocSize << _T("\t") << allocTotal << _T("\t") << long(ms.GetPhysFree()/1024/1024) << std::endl ; free_M = u_32(ms.GetPhysFree ()/1024/1024) ; memAry.at(index) = pAlloc ; ::Sleep_ms(1000) ; index++ ; if (ngCount > 100) { break ; } } for (index=0 ; index<free_M ; index++) { void* pAlloc = memAry.at(index) ; free(pAlloc) ; } } return 0; }
/LARGEADDRESSAWARE を有効にすることで 4 GB まで確保できている．

(VS)\VC\bin\EditBin.exe でも同様の設定ができるみたい．
EDITBIN リファレンス

確保したメモリのアドレスを表示する様にしてみた．
