註釋

Parallel languages rarely specify parallel I/O constructs, and existing commercial systems provide the programmer with a low-level I/O interface. We present design principles for integrating I/O into languages and show how these principles are applied to a virtual-processor-oriented language. We show how machine-independent modes are used to support both high performance and generality. We describe an automatic mode detection technique that saves the programmer from extra syntax and low-level file system details. We show how virtual processor file operations, typically small by themselves, are combined into efficient large-scale file system calls. Finally, we present a variety of benchmark results detailing design tradeoffs and the performance of various modes.
