Abstract: A CAN bus system that permits a slave node to be connected to the CAN bus. The slave node uses a preamble of a data frame transmitted by the master node on the bus to generate an internal CAN sampling clock. The slave node over-samples frames transmitted over the bus, and monitors the sampled data for a predetermined pattern, which is used to generate the slave node CAN sampling clock. Thus, the slave node does not require or include an external crystal for generating its CAN sampling clock.

Abstract: A job optimizer dynamically changes the allocation of processing units on a multi-nodal computer system. A distributed application is organized as a set of connected processing units. The arrangement of the processing units is dynamically changed at run time to optimize system resources and interprocess communication.

A job optimizer analyzes the collected metrics to dynamically arrange the processing units within the jobs. The job optimizer may determine to combine multiple processing units into a job on a single node when there is an overutilization of interprocess communication between processing units. Alternatively, the job optimizer may determine to split a job's processing units into multiple jobs on different nodes where the processing units are over utilizing the resources on the node.
