Evaluating Associativity in CPU Caches

Evaluating CPU Utilization in a Cloud Environment

Virtualization is used to ease computing resource management, resource utilization and running multiple heterogeneous or homogeneous operating systems on a single physical machine. Virtualization offers many advantages such as reducing fiscal costs, easing system migration, running legacy applications, easing backups and disaster recovery, and utilizing the shared resources over traditional dat...

Evaluating Power Consumption of D-NUCA caches

D-NUCA caches are on-chip cache memories characterized by multi-bank partitioning and data migration. They exhibit high hit rates while keeping the access latency low. As counterpart, such caches are affected by high static and dynamic power consumption. In this work we present a preliminary power consumption evaluation of a D-NUCA cache. Results show the existing balance among static and dynam...

Evaluating Dusty Caches on General Workloads

Silent stores, i.e., stores to memory that write the same value as already stored in that memory location, have been observed to occur frequently. These stores not only create redundant memory transactions, but in a multiprocessor environment result in redundant communication messages. In this paper, we quantify the frequency of such silent stores, in particular temporally silent stores, in typ...

Coherent-cache shared-memory architectures often give disappointing performance which can be alleviated by manual tuning. We describe a new trace analysis tool, clarissa, which helps diagnose problems and pinpoint their causes. Unusually, clarissa works by analysing potential contention, instead of measuring predicted contention by simulating a speciic memory system design. This is important be...
