Jelena Pjesivac-Grbovic 36156f39c2 Modification to allreduce ring algorithm: ...

- the block sizes are computed in more uniformn way.
  The first k blocks may be 1 element larger than the remaining blocks.
The algorithm passed Intel Allreduce_c and Allreduce_loc_c tests, and 
IMB-3.2 Allreduce, over TCP and both btl and mtl MX (up to 128 processes).
The algorithm still only supports commutative operations.

This commit was SVN r13738.
