摘要
Examples include a computing system comprising an input / output (I / O) device comprising a plurality of counters, each counter functioning as one of a completion counter and a trigger counter; a processing device; and a storage device. The storage device stores instructions which, in response to execution by the processing device, cause the processing device to represent a plurality of triggered operations of collective communication for high-performance computing, executable by the I / O device as a directed, acyclic graph in the storage device, with triggered operations, represented as vertices of the directed, acyclic graph and dependencies between triggered operations, represented as edges of the directed, acyclic graph; Traversing the directed, acyclic graph using a first process of identifying and marking vertices that can share a completion counter; and traversing the directed acyclic graph using a second process to assign a completion counter and a trigger counter for each vertex.
