comment is there a register corresponding to CLOCK_PROCESS_CPUTIME_ID?
@PaulA.Clayton Looking at the power ISA 2.07 it looks like the timer base is more related to something like CLOCK_REALTIME or CLOCK_MONOTONIC than CLOCK_PROCESS_CPUTIME_ID

comment How to efficiently compare vectors with C++?
@DyP Very true. I did some experiment and the performance of the longer the vector to be compared the worst this method performed. Adjusting the number of bucket (which i take reduce the number of hash collision ) might indeed solve the problem. Splitting the loop might also improved performance, by better cache coherency but also because it will reduce data depency and therefore increase ILP.(the two loop might even be in different threads if the vector are long enough). Finally , i think i might possible to use something like set or map and still get better performance than sorting
