抄録

Previously, communications in parallel programs forHigh Performance Computing (HPC) and Distributed Computing(DC) are mostly written with two-sided communicationinterfaces that are based on a pair of operations, Send andReceive. Since such interface requires explicit synchronizationbetween both sides of the communication, techniquesfor communication optimization such as overlapping are notefficiently described in many cases. On the other hand, onesidedcommunication interface is becoming important as amethod to describe asynchronous communications to enablehighly overlapped communication with computation. As oneof such interface, in this demonstration, Advanced CommunicationPrimitives (ACP) is introduced. ACP is a portableinterface that supports UDP, IBverbs of InfiniBand and Tofulibrary of K Computer. In addition to that, it is designed tobe memory efficient. For example, with 10 thousand processes, the memory consumption of ACP over UDP is estimated to beless than 1MB. Since the number of computational elements isincreasing more rapidly than the amount of available memory, this memory efficiency is becoming one of the keys for parallelprograms in HPC and DC. To show this characteristics, we runACP library on Raspberry Pi 2, and examine its performanceand memory consumption.
