A cluster is often configured with computational resources where there is only one IP visible front-end machine that hides all its internal machines from the external world. Considering clusters located in different network domains to be used in a computation, it is difficult to exploit all the internal machines of each cluster. This paper presents a PVM extension that enables us to exploit clusters in a multidomain envi- ronment so that each clustered machine can take part in a PVM compu- tation. To improve the system performance, the PVM inter-task standard communications has been replaced by a method based on UDP sockets. Moreover, the existing code written for PVM can easily be ported to use these features.

Abstract
A cluster is often configured with computational resources where there is only one IP visible front-end machine that hides all its internal machines from the external world. Considering clusters located in different network domains to be used in a computation, it is difficult to exploit all the internal machines of each cluster. This paper presents a PVM extension that enables us to exploit clusters in a multidomain envi- ronment so that each clustered machine can take part in a PVM compu- tation. To improve the system performance, the PVM inter-task standard communications has been replaced by a method based on UDP sockets. Moreover, the existing code written for PVM can easily be ported to use these features.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
