  • Patent number: 10545839
    Abstract: A method is disclosed, as well as an associated apparatus and computer program product, for checkpointing using a plurality of communicatively coupled compute nodes. The method comprises acquiring health information for a first node of the plurality of compute nodes, and determining a first failure probability for the first node using the health information. The first failure probability corresponds to a predetermined time interval. The method further comprises selecting a second node of the plurality of compute nodes as a partner node for the first node. The second node has a second failure probability for the time interval. A composite failure probability of the first node and the second node is less than the first failure probability. The method further comprises copying checkpoint information from the first node to the partner node.

  • Publication number: 20070198973
    Abstract: A computer-implemented method, system, and program product for optimizing a distributed (software) application are provided. Specifically, a configuration of a target computing environment, in which the distributed application is deployed, is discovered upon deployment of the distributed application. Thereafter, based on a set of rules and the discovered configuration, one or more optimization techniques are applied to optimize the distributed application. In a typical embodiment, the set of rules can be embedded in the distributed application, or they can be accessed from an external source such as a repository.

  • Publication number: 20070182327
    Abstract: Disclosed are a method of manufacturing an electrode for generating plasma, which is capable of improving durability of the electrode and reducing production costs of the electrode, an electrode structure, and an atmospheric pressure plasma apparatus using the same. The plasma electrode structure comprises a pair of electrodes isolated from each other, a plasma generating space formed between the pair of electrodes, and an oxide coating layer formed uniformly on at least one of surfaces of the pair of electrodes.
