Reuse Distance Analysis
Cache is one of the most widely used components in today's computing systems. Its performance is heavily depended on the locality in programs. Till now, the analysis of program locality relies on expensive cache simulation. As machine cache becomes increasingly complex and adaptive, more eÆcient and accurate methods are needed to nd the best cache con guration for each program or even each part...
متن کاملPath-Based Reuse Distance Analysis
Profiling can effectively analyze program behavior and provide critical information for feedback-directed or dynamic optimizations. Based on memory profiling, reuse distance analysis has shown much promise in predicting data locality for a program using inputs other than the profiled ones. Both wholeprogram and instruction-based locality can be accurately predicted by reuse distance analysis. R...
متن کاملA Beyond Reuse Distance Analysis: Dynamic Analysis for Characterization of Data Locality Potential
Emerging computer architectures will feature drastically decreased flops/byte (ratio of peak processing rate to memory bandwidth) as highlighted by recent studies on Exascale architectural trends. Further, flops are getting cheaper while the energy cost of data movement is increasingly dominant. The understanding and characterization of data locality properties of computations is critical in or...
متن کاملMemory Performance Analysis for Parallel Programs Using Concurrent Reuse Distance
Performance on multicore processors is determined largely by on-chip cache. Computer architects have conducted numerous studies in the past that vary core count and cache capacity as well as problem size to understand impact on cache behavior. These studies are very costly due to the combinatorial design spaces they must explore. Reuse distance (RD) analysis can help architects explore multicor...
متن کاملSimilarity Beyond Distance Measurement
One of the keys issues to content-based image retrieval is the similarity measurement of images. Images are represented as points in the space of low-level visual features and most similarity measures are based on certain distance measurement between these features. Given a distance metric, two images with shorter distance are deemed to more similar than images that are far away. The well-known...
