An NAT-Based Communication Relay Scheme for Private-IP-Enabled MPI over Grid Environments

Abstract

Abstract. In this paper we propose a communication relay scheme combining the NAT and a user-level proxy to support private IP clusters in Grid environments. Compared with the user-level two-proxy scheme used in PACX-MPI and Firewall-enabled MPICH-G, the proposed scheme shows performance improvement in terms of latency and bandwidth between the nodes located in two private IP clusters. Since the proposed scheme is portable and provides high performance, it can be easily applied to any private IP enabled solutions including the private IP enabled MPICH solution for Globus toolkit.

MCMPI: A library with elasticity for multi‐domain and public cloud environments

“…Solutions based on NAT (Network Address Translation) have also been proposed 2 where the transmission of messages through the MPI library over grid environments is performed by the front‐end node of the cluster through a NAT service.…”

MCMPI: uma biblioteca com elasticidade para ambientes com múltiplos domínios e nuvem pública

“…Também já foram propostas soluções baseadas em NAT (Network Address Translation) [Choi et al 2004] onde a transmissão de mensagens através da biblioteca MPI sobre ambientes de grid é realizada pelo nó front-end do cluster através de um serviço NAT. O uso de NAT gera um ganho de desempenho uma vez que um pacote já encontra seu destino através da camada de rede não precisando passar pelas camadas seguintes.…”

A grid-aware MIP solver: Implementation and case studies

“…Park et al [38] present MPICH-GP, an extension of MPICH-G2 for supporting Private IP, whereas Velusamy et al [39] describe a solution based on IMPI standard with Network Address Translation mechanism and Das et al [24] propose a solution based on RSIP. Papers on similar topics are written by Heymann et al [40] and Choi et al [41]. Chen and Shmidt [42] present a performance analysis on hierarchical grid system with different bandwidths between clusters.…”
