PCP: Fast Cluster File Replication

PCP is a system for replicating files on multiple nodes of a PC cluster. Replication is done by building an n-ary tree of TCP sockets and using parallelized, pipelined data transfers which use RSA authentication. For large file transfers or replication on many nodes, PCP provides highly efficient data transfers when compared to existing alternatives (e.g. NFS).

A heartbeat thread has been added to reduce timeout detection time when a node crashes hard. Finally, additional options are available, including the specification of an alternative TCP port.
