Hi there, This mail is to check if currently Valgrind provides any tool/option
which can be utilized to do profiling of a running process to know what % of
memory allocation made by the process is NUMA optimized. By "NUMA optimized"
allocation I mean, "if a process running on a processor of specific Node then
through out its lifetime what amount of memory it allocates from local
node(which is NUMA optimized way) and what % of allocation it make from remote
NUMA node(which is not optimized way due to the latency overhead involved).
Benefits:This report will provide a good understanding of if a process is able
to make full use of NUMA architecture performance benefits in terms of memory
allocation. If not then it will allow the developer/Admins to fine tune their
process/applications to be NUMA friendly in-terms of memory allocations.
