(or, at large scale, hierarchically) give small units of work to each worker as it nears completion of its previous unit. Since, in BSP, all tasks in the previous stage have to finish before the current stages begin, such design eliminates stragglers. WebbEnsuring load balancing only requires a relatively small cache. In addition, to achieve high throughput, the front-end cache must be fast enough to keep the cluster of nodes behind it busy. The paper proves that the cache need only store O(nlogn) entries to provide good load balance, where n is the total number of back-end nodes.
