“…Regarding client-server connections, CPAM assumes that the client is able to simultaneously support the various distribution systems of the servers it wishes to talk to. The CHAIMS architecture, along with the CHAIMS compiler [9], enables the generation of such a client. This process is described in next section.…”

Abstract. Software composition is critical for building large-scale applications. In this paper, we consider the composition of components that are methods offered by heterogeneous, autonomous and distributed computational software modules made available by external sources. The objective is to compose these methods and build new applications while preserving the autonomy of the software modules. This would decrease the time and cost needed for producing and maintaining the added functionality. In the following, we describe a highlevel protocol that enables software composition. CPAM, CHAIMS Protocol for Autonomous Megamodules, may be used on top of various distribution systems. It offers additional features for supporting module heterogeneity and preserving module autonomy, and also implements several optimization concepts such as cost estimation of methods and partial extraction of results.

“…So far we have investigated its use in two different settings: with a SQL-based language as front-end that composes the megamodule methods in a way similar to data [Burback, personal communication], and within the CHAIMS system (Compiling High-level Access Interfaces for Multi-site Software) [9] with the composition language CLAM [IO] as front-end.…”

One important facet of sohare reuse is the reuse of autonomous and distributed computational services. Components or applications offering services stay at the provider's site, where they tie developed, kept securely, operated, maintained, and updated. Instead of purchasing software components, the customer buys services by invoking methods provided by these remote applications over the Internet. Due to the autonomy of the services, this reuse model causes specific requirements that differ from those where one builds one's own system from components. These requirements have led to the definition of CPAM, a protocol for reusing remote and autonomous services. CPAM can be used on top of various distribution systems, and offers features like presetting of attributes, run-time estimation of costs and having several calls for setup, invocation and result extraction. The CPAM protocol has been successfully used within CHAIMS, a reuse environment that supports the generation of client applications based on CPAM.

“…Thus, much developing effort can be replaced by plugging in commercially or freely available components. This paper presents CoMMM (Common object-oriented Method ManageMent), a general architecture and objectoriented framework for scientific computing over global networks based on the experiences made with MMM, standards like CORBA, and first experiences with megaprogramming [15,14]. As in MMM, the aim of CoMMM is that neither the provider of new methods nor the consumer accessing them needs to know anything about the underlying technology or needs to read this paper.…”

In network computing, methods (scripts, programs, models, macros, etc.) are executed at remote sites in a transparent way. Distributed Method Management Systems (DMMSs) for network computing allow easy dissemination of new methods over global networks by supporting the publishing of new methods as well as finding and executing existing methods. For consumers, DMMSs replace awkward telnet sessions or debugging cycles for down-loaded public domain software with click'n'go access to methods running in a suitable execution environment. For providers, DMMSs simplify the process of putting methods on the Web to a minimum. In scientific computing, methods are typically scripts for scientific computing packages like Mathematica or Matlab, compiled programs, or stand-alone Internet servers providing computational services. Methods can be applied to data sets available within the DMMS or anywhere on the Internet. The paper presents CoMMM, an object-oriented application framework and runtime environment for DMMSs. CoMMM wraps methods into CORBA objects and provides CORBA Common Facilities for publishing, finding and executing methods.
