Conteúdo: 	Private caches are essential to reduce the bus congestion and to cope with the latency of memory accesses in bus-based shared memory multiprocessors. In such systems, snooping cache coherence protocols are commonly accepted as an effective approach to keep shared data coherent, since they utilize the simple and effective broadcasting capability of a single bus. This group of processors connected via shared and single bus, is a simplest cluster. Nowadays, modern and scalable shared-memory multiprocessors use such organization as baseline to interconnect several of these clusters through high-speed networks. These systems are known as cluster-based multiprocessors. With the purpose to reduce the communication among clusters, a large cache shared by all processors within the cluster can be considered. In this study, we called this cluster cache as "Network Cache" (NC). Therefore, a NC is included to reduce the traffic in the communications network. It is used to cache data from non-local memory modules (but not the data from the local memory). Since this cache only needs to appear to be fast compared to non-local memory modules (which involve transfers through the communications network), it can be built using the same DRAM technology as used for the local memory. In this paper, we study the design and implementations trade-offs, via a qualitative evaluation, taken into account the potential benefits and limitations that such large caches could insert on the performance in scalable shared-memory multiprocessors systems.
