Improving the effectiveness of automatic compilation for multiprocessors
Shared-memory multiprocessors, built out of the latest microprocessors, are becoming a prevalent computer architecture. To effectively harness the power of these machines it is important that we find all the available parallelism in the programs. We have developed an interprocedural optimizer with novel array analysis techniques. We have shown that these analyses in combination with a full suite of scalar analyses can be successful in finding large amounts of parallelism in general scientific applications. Another important factor in obtaining parallel performance is the effective utilization of the memory hierarchy. In parallel applications false sharing and cache conflicts between processors can significantly reduce performance. We have developed the first compiler that automatically performs a full suite of data transformations (a combination of transpose, strip-mining and padding). We have shown that the performance of many benchmarks are drastically improved after the data transformations.
