    Abstract: A system, and computer program product for tolerating failures using concurrency in a cluster are provided in the illustrative embodiments. A failure is detected in a first computing node serving an application in a cluster. A subset of actions is selected from a set of actions, the set of actions configured to transfer the serving of the application from the first computing node to a second computing node in the cluster. A waiting period is set for the first computing node. The first computing node is allowed to continue serving the application during the waiting period. During the waiting period, concurrently with the first computing node serving the application, the subset of actions is performed at the second computing node. Responsive to receiving a signal of activity from the first computing node during the waiting period, the concurrent operation of the second computing node is aborted.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining image search results. One of the methods includes scheduling a first computation for execution on each of a first plurality of worker processes. The first computation changes a respective state of each of one or more of the first worker processes from a first state to a second state. A respective second computation is scheduled for execution on each of a second plurality of worker, where each respective second computation will use a different value for a particular variable for two or more of the second plurality of worker processes. The respective state of each of the second plurality of worker processes is updated from the second state to a third state, where the third state corresponds to execution of the second computation using a first value of the particular variable.

    Abstract: Techniques for managing disaster recovery sites are disclosed. In one particular embodiment, the techniques may be realized as a method for managing disaster recovery sites comprising generating a heartbeat at a first node, transmitting the heartbeat from the first node to a second node, determining whether a network connection between the first node and the second node has failed, determining whether the second node has received an additional heartbeat from the first node, and changing a state of the secondary node based on the determination of whether the second node has received the additional heartbeat.

    Abstract: A solutions manager supports computing solutions running on hosts in an adaptive computing environment by utilizing remote processes or agents placed on the hosts. A remote agent is associated with a computing solution and placed on the host on which the computing solution is running. When the computing solution is relocated to a new host, the remote agent associated with the computing solution is also automatically relocated and restarted on the new host.
