VM Validator Help

The Paragraphs tab displays a tabular representation of all the memory in the target program. This is known as the paragraphs view.




The paragraphs view displays information about a process's virtual memory usage whilst the process is running. If there is no target program being monitored, the paragraphs view does not display any data.


For memory paragraphs where more than one memory status (or swap count etc) is present for the pages in the memory paragraph the display will list the aggregate values (if two pages have been swapped a total of 33 times (18 and 15 times each) the display will show a swap count of 33).


The data displayed is data per virtual memory paragraph (as defined by the operating system dwAllocationGranularity returned from Win32 API call GetSystemInfo()).

A memory paragraph is 64Kb.





Each column can be sorted by clicking the column header to move sorting to that column. Clicking the current column header again reverses the sort direction.



Viewing swap behaviour


To view virtual memory being swapped select the Swap column so that the sort arrow points downwards.


The display will show pages that have been swapped with the number of times they have been swapped shown in the Swap column.


When a page gets swapped it will be promoted at the top of the swap column for 1 second then be displayed back in it's regular sorted position.

When combined with the highlight swapped memory option on the Display Settings dialog you can very easily see pages being swapped.
