- PublicationAccès libreA dynamically configurable environment for high performance computing(2000)
;Abdennadher, Nabil ;Babin, Gilbert; Kuonen, PierreCurrent tools available for high performance computing require that all the computing nodes used in a parallel execution be known in advance: the execution environment must know where the different "chunks" of programs will be executed, and each computer involved in the execution must be properly configured. In this paper, we describe how the Web Operating System (WOS™) environment may be used to dynamically locate available computers to perform such computations and how these computers are dynamically configured.
The WOS™ (?) is a virtual operating system which is suitable for supporting and managing distributed/parallel processing on the Internet. Central to the WOS™ architecture are the communication protocols, which may be seen as the "glue" of the whole environment. Communication between nodes is realized through a generic service protocol and a simple discovery/location protocol (?).
The service protocol may be versioned to support specialized services. In the present research, we focus on the design of such a version for High Performance computing. This version essentially locates nodes able to execute parallel programs, identifies nodes available for participating in the parallel execution, and sets up an execution environment on the dynamically selected set of nodes. - PublicationAccès libreA WOS-based solution for high performance computing(2001)
;Abdennadher, Nabil ;Babin, GilbertMost of the development environments for high performance parallel applications require that all the computing modules and resources be known in advance. The execution environment must know where the different program modules will be executed, and must properly configure each computer involved in the execution. We describe how the Web Operating System (WOSTM) environment may be used to dynamically adjust the granularity of parallel programs, locate available computers to perform the computations and how these computers are dynamically configured. The WOS (P. Kropf et al., 2000) is a metacomputing environment suitable for supporting and managing distributed parallel processing on wide and local networks. Communication between WOS nodes is realized through a generic service protocol (WOSP) and a discovery/location protocol (WOSRP). WOSP may be versioned to support specialized services. The authors focus on the design of two such versions for parallel/distributed applications and high performance computing. These versions support the location and setup of computational nodes for these applications. - PublicationMétadonnées seulementA WOS-based solution for High Performance computing(: IEEE Computer Soc, 2001)

In this paper, we describe how the Web Operating System (WOS (TM)) environment may be used to dynamically adjust the granularity of parallel programs, locate available computers to perforin the computations and how these computers are dynamically configured.
