GLADE allows a program to be configured as multiple partitions executing concurrently on separate machines and communicating with each other. GLADE supports several network protocols and provides replication and replay capabilities.

Key Features

• - Run-time library for Annex E (Distributed Systems) support
• - Management of inter-partition communication
• - Tools to define partition location and content
• - Support for heterogeneous environments
• - Data filtering (encryption, compression)
• - Replication and embedded capabilities
• - Support for distributed and client/server paradigms

Contents

• GNATDIST: a tool for building distributed and client/server applications, using a powerful Ada-based descriptive notation
• GARLIC (Generic Ada Reusable Library for Interpartition Communication): a full PCS (Partition Communication Subsystem)

Building Distributed Applications with GLADE

• - Write the application as if not distributed
• - Identify remote procedures, shared variables, and distributed objects
• - Build and test the non-distributed application (gnatmake)
• - Write a configuration file for the partitioning
• - Build and test the partitioned/distributed program (gnatdist)

Streams

• - Used for exchanging data between partitions (marshalling/unmarshalling)
• - Identify remote procedures, shared variables, and distributed objects
• - Build and test the non-distributed application (gnatmake)
• - Write a configuration file for the partitioning
• - Build and test the partitioned/distributed program (gnatdist)

Annex E features

• - Partitions and nodes
• - Intuitive display (Pure, Remote_Types, Shared_Passives, Remote_Call_Interface)
• - Consistency (Partition_Id)
• - Remote calls and exceptions
• - Streams used for communication

GLADE on Windows NT & XP

• - Minimal porting effort; all standard UNIX tools available
• - Graphical output (X, TCL/Tk)
• - Full language support including real time support for Annex D
• - Can be used to access Win32 interface from Interix applications
• - Seamless communication between Unix and Win32 code
