A compiler configured to configure memory nodes with a ready-to-read credit counter and a write credit counter. The ready-to-read credit counter of a particular upstream memory node initialized with as many read credits as a buffer depth of a corresponding downstream memory node. The ready-to-read credit counter configured to decrement when a buffer data unit is written by the particular upstream memory node into the corresponding downstream memory node, and to increment when the particular upstream memory node receives from the corresponding downstream memory node a read ready token. The write credit counter of the particular upstream memory node initialized with one or more write credits and configured to decrement when the particular upstream memory node begins writing the buffer data unit into the corresponding downstream memory node, and to increment when the particular upstream memory node receives from the corresponding downstream memory node a write done token.

A computer-implemented method comprises a topological communications configurator (TCC) of a computing system determining a connections-optimized configuration of processors among compute nodes of the system. Processors included in the compute nodes can execute compute workers of an application of the system and can form intranodal segments of an internodal interconnection topology communicatively coupling the intranodal segments. The intranodal segments can be interconnected via an internodal interconnections fabric. The TCC can determine the connections-optimized configuration based on internodal communications costs corresponding to communications routes among the internodal segments via the internodal interconnection fabric. The computing system can comprise the TCC and can comprise a data-parallel computing system.
