- Re: how to get physical memory address from virtual memory address
Where does the physical memory come from when you turn on virtual memory overcommits? Look at Documentation/vm/overcommit-ac counting in your kernel sources. Setting vm.overcommit_memory=1 is indeed useful in some circumstances but can lead to unpredictable process deaths.- Editing the memory settings for a Java application

This is not a task that should be performed by the user-level process. You can't for example test the memory which is permanently mapped by kernel (which user-level process is not allowed to access). For memory diagnostics, tools specifically crafted for such tasks should be used (such as memtest86).- Re: how to get physical memory address from virtual memory address
Really? So what happens when the page is swapped out? It's still a valid virtual address, but there's no valid physical address behind it, until it's swapped back in by a page-fault or the prefetcher. -n- Re: how to get physical memory address from virtual memory address
The virtual address allocation *does not* allocate physical pages to the allocated block - you only get a slice of the address space of your process. The virtual address is connected (maybe temporarily) to a physical page when it's accessed and a page fault handler decides to give the physical addresses.- Anyone know about computers Virtual memory Problem) (London, Price: 30)

Not true. When the respective page is swapped out, there is no physical address associated to given virtual address.
