on modern multi-core platforms parallel performance of memory bandwidth bounded applications not scale number of cores. usually, speedup observed number of cores, after performance saturates. synthetic example well-known stream benchmark , used report achievable memory bandwidth, i.e., memory bandwidth @ saturation point. consider following results of stream benchmark (triad) on single xeon e5-2680 peak memory bandwidth of 42.7gb/s (ddr3-1333): 1 core 16 gb/s 2 cores 30 gb/s 3+ cores 36 gb/s stream scales 1 2 cores, above 3 cores performance constant. my question is: determines memory bandwidth can achieved single cpu core ? since question broad, narrow down above mentioned architecture: how can predict stream 1 thread give me 16 gb/s specs of e5-2680, or looking @ hardware counters etc? for single core major factor cpu frequency , cpu micro architecture, speed of single core make requests bus , how cpu can predict memory location you're going access. cpu de...
