I like to find out what program (even after quitting) has allocated memory to the "inactive slot". Is this possible and if so what is a name of such a program?

Does Activity Monitor not do this?

No it shows only memory that is being used - active memory. But what programs are being stored in the "inactive memory"?

Select "Inactive Processes" from the drop down list in Activity Monitor's Toolbar.

top shows you every single process running on the system, and its memory consumption. Activity Monitor is simply a GUI for top.

I guess I am not being clear- inactive processes still take up active ram and thus their RAM usage is tagged as active. What I'm interested in is when I close a program, for instance- iphoto , the ram it used for itself is not flushed back into "free" state after I quit it,rather it is tagged as "inactive". I would like to view what programs are using ram in its inactive state.

Technically nothing is "using" RAM in the inactive state. Its just marked with what it once belonged to. If you start another app that needs a big chunk of RAM it will be dramn from the free + inactive pool. I'm not aware of anything that lets you see what the inactive RAM belonged to, some poking around in the xnu sources maybe in order.

What exactly are you trying to do? Is this just curiosity, or do you want this for some reason? There may be a better way to do what you want...

Yes it is out of curiosity - to gain a better understanding of OS X memory management. Does it have preference to which closed programs memory it swapped out first and so forth.
