Hill-climbing SMT processor resource distribution
Seungryul Choi, Donald Yeung
Article No.: 1
DOI: 10.1145/1482619.1482620

The key to high performance in Simultaneous MultiThreaded (SMT) processors lies in optimizing the distribution of shared resources to active threads. Existing resource distribution techniques optimize performance only indirectly. They infer...

Distributed hash sketches: Scalable, efficient, and accurate cardinality estimation for distributed multisets
N. Ntarmos, P. Triantafillou, G. Weikum
Article No.: 2
DOI: 10.1145/1482619.1482621

Counting items in a distributed system, and estimating the cardinality of multisets in particular, is important for a large variety of applications and a fundamental building block for emerging Internet-scale information systems. Examples of such...
