| Zusammenfassung: | Abstract: "Doacross can exploit the parallelism of a Do loop with cross-iteration dependences. All previous approaches to Doacross execution assumed the uniform memory access (UMA) architecture. In this paper, we propose a Doacross execution scheme for the distributed shared memory (DSM) architecture. Our scheme uses direct communication and static message passing. Our communication is direct because a producer writes (or sends) data directly to the nearest shared memory (NeSM) of its consumer. Our message passing is static in the sense that a message is bound to a buffer location determined at compile time We present compiler algorithms that transform a Doacross loop into the proposed execution scheme and derive conditions that can reduce the extra storage needed for message buffers. The preliminary results show that the proposed scheme can outperform approaches that ignore the features of the DSM architecture, i.e. simply utilize DSM architecture as UMA architecture. |
