Just a few years ago, parallel computers were tightly-coupled SIMD, VLTW, or MIMD machines. Now, they are clusters of workstations connected by communication networks yielding ever-higher bandwidth (e.g., Ethernet, FDDI, HiPPI, ATM). For these clusters, compiler research is centered on techniques for hiding huge synchronization and communication latencies, etc. — in general, trying to make parallel programs based on fine-grain aggregate operations fit an existing network execution model that is optimized for point-to-point block transfers. In contrast, we suggest that the network execution model can and should be altered to more directly support fine-grain aggregate operations. By augmenting workstation hardware with a simple barrier mechanism (PAPERS: Purdue's Adapter for Parallel Execution and Rapid Synchronization), and appropriate operating system hooks for its direct use from user processes, the user is given a variety of efficient aggregate operations and the compiler is provided with a more static (i.e., more predictable), lower-latency, target execution model. This paper centers on compiler techniques that use this new target model to achieve more efficient parallel execution: first, techniques that statically schedule aggregate operations across processors, second, techniques that implement SIMD and VLIW execution.
