TODO
====

Might be trivial
----------------

 * Use a dynamic lib to load tracer reader into node instead of using process output forward, might bt ok by using nodejs c++ wrappers

Not so much work
----------------

 * Add support for mmap/munmap/mremap
   Need to track overlap and gaps on munmap to track the memory it frees.
 * Add usage of stack ID infos in time charts. Need to add them with time classes
 * Add option MALT_SLIENT to remove output.
 * Add option to filter exe for instr
 * Add option to not instrument childs.
 * Do reuse of per thread structure
 * Permit to mark some user function as alloc function for inclusive/exclusive (ideally, click on function and 'mark as alloc wrapper')
   It might apply in isAllocFunction()
 * Remove the libs virtual memorty in virtual memory charts ?
 
Need work
---------

 * Fix numbering of .trace files in MPI mode (it use PID instead of rank)
   Delay open after MPI_Init. Need to manage the fact that the buffer might be too small if too
   much allocations are done before.
 * Add profiling of physical/virtual ratio
   Expect to use move_pages but not usable when NUMA is disable, need to use /proc/PID/pagemap
 * Add profiling of NUMA mappings
 * Maybe store the stack tree as a tree instead of list of call stack (can reduce output file size of a factor 2), but
   need some patch in GUI to rebuild the list representation used everywhere.
   Not so much work for the lib side as there is a tree class already available, but might need some work on the webview side.
   A first step might be to juste regenerate the current format in memory when loading the file in the client MaltProject class.
 * In webview, page for source annotations : add tree view of costs for call site (by default when source are not availables) [CFG]
 * Integration of tracer. Need to call the reader through node and return the informations in GUI. Interesting to do :
    - possibility to get memory used at some timestep by each call stacks (return ids, chunk count and memory size), partially done in trace reader
    - possibility to get the time chart of a specific call site
    - possibility to get size distribution of a specific call site and maybe timestep
 * Need to add integration of trace system into webview
