Abstract:
The number of processors embedded on high performance
computing platforms is growing daily to satisfy users desire for solving
larger and more complex problems. Parallel runtime environments have
to support and adapt to the underlying libraries and hardware which
require a high degree of scalability in dynamic environments. This paper
presents the design of a scalable and fault tolerant protocol for sup-
porting parallel runtime environment communications. The protocol is
designed to support transmission of messages across multiple nodes with
in a self-healing topology to protect against recursive node and pro-
cess failures. A formal protocol verification has validated the protocol
for both the normal and failure cases. We have implemented multiple
routing algorithms for the protocol and concluded that the variant rule-
based routing algorithm yields the best overall results for damaged and
incomplete topologies.
