Title: Efficient Message Passing on Multi-Clusters: An IPv6 Extension to Open MPI
Author(s): Christian Kauhaus, Adrian Knoth, Thomas Peiselt, Dietmar Fey
Abstract:
At our university, different institutes have installed their own
cluster computers.
Connecting several of these clusters to perform distributed
high-performance computing requires message passing
spanning heterogeneous network structures.
One problem is that private IPv4 addresses inside clusters, although
common and suitable for internal communication,
preclude end-to-end connectivity.
To establish multi-cluster message passing in such a context, we propose to
use MPI over IPv6. In this article, we
present our IPv6 extension to Open MPI, which is able to cope with
mixed IPv4/IPv6 environments and delivers high performance levels.
