Can you change the spec?
  
   Not really. It will break all existing codes.
  
  I meant as in eg. submit changes to MPI-3

 MPI spec tries to be backward compatible. And MPI-2 spec is 10 years
 old, but MPI-1 is still in a wider use. HPC is moving fast in terms of HW
 technology, but slow in terms of SW. Fortran is still hot there :)

Agreed.
many many people dislike incompatible specification change.

We should accept real world spec.

 In my world, TR stands for Token Ring.  Nowhere in this patch do you
 explain what TR means to you!

may be, TR is Tlb Register. see IA64 itr instruction :)
