Efficient high performance collective communication for the cell blade
Qasim Ali, Samuel Pratt Midkiff, Vijay S. Pai · 2009
This paper presents high-performance collective communication algorithms and implementations that exploit the unique architectural features of the Cell heterogeneous multicore processor. This paper specifically describes novel algorithms for the barrier, broadcast, reduce, all-reduce, and all-gather collective operations, and shows the efficiency of these by comparing them to the previous
