The growing gap between processor and memory speeds has lead to complex memory hierarchies as processors evolve to mitigate such divergence by exploiting the locality of reference. In this direction, the BSC performance analysis tools have been recently extended to provide insight into the application memory accesses by depicting their temporal and spatial characteristics, correlating with the source-code...
Multi-tiered memory systems, such as those based on Intel® Xeon Phi™processors, are equipped with several memory tiers with different characteristics including, among others, capacity, access latency, bandwidth, energy consumption, and volatility. The proper distribution of the application data objects into the available memory layers is key to shorten the time– to–solution, but the way developers...
