What is the relation of this benchmark to the Effective Communication Bandwidth (b_eff) benchmark?
In this benchmark, latency and bandwidth are measured mainly with three communication patterns (ping-pong, random ring, natural ring) and two message sizes (8 byte for latency and 2,000,000 bytes for bandwidth measurements) and these different results are reported independently. The buffer memory is always reused in a loop of measurements. The goal of b_eff is to compute an average bandwidth value that represents several ring patterns (sequentially and randomly ordered) and 21 different message sizes. Memory reuse is prohibited.
