Abstract: We propose to move to runtime part of the compile-time analysis needed to generate the communication code for distributed-memory systems. Communication stages on distributed-memory systems have a significant impact on performance, thus the reduction of the communication times is key for improving performance in terms of runtime execution. We have developed a technique that uses a hierarchical tiling array library to represent and manage rectangular index spaces at runtime. The data to be received and/or sent by a local process to another one is calculated by intersecting the set of indexes read or written by a process with the set of indexes written or read by the local process.
