CSPL 環境的通訊方式

Abstract

這篇論文描述 CSPL (Concurrent Software Process Language) 環境中 所使用的通訊方式。CSPL 提供了同步及非同步的通訊機制，前者使用了 Ada 的 rendezvous 方法，並使用 UNIX 系統裡的 named pipe 檔案來製 作；後者是由 "inform" 敘述來達成，並使用共用資料 (shared data) 來製作。更重要的一點是，由於主從式架構的簡單性、有效率、而且易於 維護，整個 CSPL 環境即採用此方法來架構，並使用了著名的 SUN RPC 機制來實作之。 This thesis describes the communication scheme used in the CSPL (Concurrent Software Process Language) environment. CSPL provides both synchronous and asynchronous communication mechanisms. The former utilizes Ada rendezvous constructs which is implemented with UNIX named pipe file. The latter is done by the "inform" statement which is implemented by shared data. More importantly, the client-server architecture is used for its simplicity, efficiency, and maintainability. The well- known SUN RPC mechanism is used in the implementation.
