  • Patent number: 8566803
    Abstract: Embodiments of the invention may be used to generate a benchmark profile for a computing job configured to execute on distributed systems. The benchmark profile may be used to predict the performance of components of a computing job for a variety of different distributed computing system architectures. A profiling tool evaluates the computing job to identify the particular performance characteristics of the application and match this with benchmarks that are most representative of the identified performance characteristics and store them in the benchmark profile. The identified benchmarks may then be run on different configurations of a distributed computing system in order to predict the performance of the application for a variety of scenarios.

  • Patent number: 8127032
    Abstract: One embodiment of the invention provides a method to identify a preferred system configuration for a distributed system to use for executing a given computing job. A benchmark profile may specify a collection of benchmarks representative of the job, and the collection of benchmarks may be executed across various permutations of compute nodes that are part of the distributed system. That is, the benchmark profile identifies one or more benchmarks which best represent the runtime characteristics of the computing job. The collection of benchmarks may be executed to predict the performance of the computing job using different permutations of available nodes, before deploying the job.

  • Patent number: 6763457
    Abstract: A method for booting a user station in a computer network in which a boot sequence is initiated by retrieving boot parameter information from a remote boot server. If the boot server fails to supply information for at least one boot parameter, it is determined whether a default value may be used for the boot parameter. If a default value may be used, a default value is retrieved from local nonvolatile storage. Each entry in the boot parameter table may include a default indicator for determining whether the default value is used if the boot server fails to supply a value for the associated boot parameter. The boot parameter table may include an override indicator to indicate whether a parameter value retrieved from the boot server is overridden.
