Program Taktuk scheduler
Taktuk is a parallel and scalable remote execution tool for clusters or intranets. It works through execution propagation using standard remote execution protocols (rsh, ssh, etc.). The schedule of remote calls automatically adapts to the protocol used, as well as to network and remote hosts loads. A grammar can be optionally provided to describe the environment, hence providing increased overall deployment speed in the context of a complex topology, for instance in a grid environment. The launch delay can be bounded in order to bypass slow nodes. It provides complete IO and signal redirection to the original console user. Experimental results give very good response times, in the order of 500 milliseconds for a 225-node cluster (Pentium III 733 interconnected by Ethernet 100). This software is used in the Ka-run project.
