The mblocks_allocated variable should give me what I want.
I think having access to this would also be useful to people who are profiling their programs. You see a few papers where people want to report how much memory their application needs, and having a high-water mark is usually good enough. Beats trying to get the information from top.
Note that this only counts memory allocated by the GHC storage manager; it doesn't include the data segments, malloc(), the C stack, or other mmap()'d stuff. Be careful if your program is using any of these other allocation methods (perhaps via an external library through the FFI).
Ah, that's a good point. I didn't think of that. For what it is worth I've put a simple Haskell wrapper to mblocks_allocated on the web. It provides this function: megaBytesAllocated :: IO Integer On my simple tests it seems reliable, when compared to what top says. I've put it here in case anyone wants to use it: http://www.cs.mu.oz.au/~bjpop/code.html Cheers, Bernie.
