Log Message:
Changed the order of operations for global sums of arrays.
 o the global sum used to accumulate sequentially over all tiles on a single
   process and then the result be passed to _GLOBAL_SUM()
 o now we create a sum per tile and accumulate the sums
   - this should fix differences in sum for two tiles on 1 or 2 processors
   - this may help when using more than2 tiles but is not guaranteed
   - introducing a gather operation in GLOBAL_SUM() will fix differences
     for multiple tiles but only for fixed tiles configurations
   - an array based sum function is needed to make this independent of
     tile configuration
