Request queues for interactive clients in a shared file system of a parallel computing system

摘要

Interactive requests are processed from users of log-in nodes. A metadata server node is provided for use in a file system shared by one or more interactive nodes and one or more batch nodes. The interactive nodes comprise interactive clients to execute interactive tasks and the batch nodes execute batch jobs for one or more batch clients. The metadata server node comprises a virtual machine monitor; an interactive client proxy to store metadata requests from the interactive clients in an interactive client queue; a batch client proxy to store metadata requests from the batch clients in a batch client queue; and a metadata server to store the metadata requests from the interactive client queue and the batch client queue in a metadata queue based on an allocation of resources by the virtual machine monitor. The metadata requests can be prioritized, for example, based on one or more of a predefined policy and predefined rules.

1. A metadata server node for use in a file system shared by one or more interactive nodes and one or more batch nodes, wherein said one or more interactive nodes comprise one or more interactive clients to execute one or more interactive tasks and wherein said one or more batch nodes execute one or more batch jobs for one or more batch clients, said metadata server node comprising:
a virtual machine monitor; an interactive client proxy to store metadata requests from said one or more interactive clients in an interactive client queue, wherein said metadata requests require a lookup of metadata; a batch client proxy to store metadata requests from said one or more batch clients in a batch client queue; a metadata server to store said metadata requests from said interactive client queue and said batch client queue in a metadata queue based on an allocation of resources by said virtual machine monitor; and wherein said interactive client proxy, said batch client proxy and said metadata server are implemented as a virtual machine.
