In this paper, we present a PVM extension which through a middleware solution based on the H2O distributed meta- computing framework, permits us to build a parallel vir- tual machine composed of hosts located across multidomain clusters. In the H2O framework, we have developed specialized proxy pluglets used to route PVM messages among compu- tational resources placed in different network domains that firewalls can shield should the need arise. The simulation tests that we have performed showed a smaller time overhead in communications across the prox- ies. However, this is acceptable if we consider the benefits gained in utilizing resources that we can now exploit ow- ing to the fact that they are often located on non-routable private networks. PVM applications can be ported into this system without modifications.

Abstract
In this paper, we present a PVM extension which through a middleware solution based on the H2O distributed meta- computing framework, permits us to build a parallel vir- tual machine composed of hosts located across multidomain clusters. In the H2O framework, we have developed specialized proxy pluglets used to route PVM messages among compu- tational resources placed in different network domains that firewalls can shield should the need arise. The simulation tests that we have performed showed a smaller time overhead in communications across the prox- ies. However, this is acceptable if we consider the benefits gained in utilizing resources that we can now exploit ow- ing to the fact that they are often located on non-routable private networks. PVM applications can be ported into this system without modifications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
