Abstract: A present invention embodiment requests resources for a set of tasks from different resource providers. The set of tasks includes first tasks and second tasks of longer duration than the first tasks. The resources are revocable by the different resource providers based on processing demand. Performance of the first tasks is initiated on the resources, and stable resources are identified based on revocation of the resources during performance of the first tasks. Performance of the second tasks are initiated on the identified stable resources. Requests for the resources to the different resource providers are adjusted based on resource provider information collected in response to completion of the set of tasks.

Abstract: A block of data intended for a set of receiving computer systems comprising a first system and a second system is divided into a set of equal-size portions. A first portion of the set of portions is transmitted from a first file server storing the block of data to the first system. The first portion is relayed from the first file server to a second file server concurrently with the transmitting. The first portion of the set of portions is transmitted from the second file server to the second system.

Abstract: The present invention relates to a method, system and computer program product for task failover in an unstable environment, wherein the unstable environment includes a plurality of reclaimable nodes. According to the method, it is monitored if any node of the plurality of reclaimable nodes is to be reclaimed. Whether a task on any node of the plurality of reclaimable nodes is recoverable is determined. Responsive to the task being recoverable, data of the recoverable task is stored. Responsive to a node being reclaimed and the task on the reclaimed node being recoverable, at least one associated task of at least one associated node of the reclaimed node is notified to wait.

Abstract: Methods that can protect sensitive data are provided. One method includes determining, by a processor, whether a user is focusing on an obscured set of sensitive data displayed on a computing device, clarifying the obscurity of a portion of the displayed set of sensitive data in response to determining that the user focusing on the portion of the displayed set of sensitive data, and maintaining the obscurity of one or more other portions of the displayed set of sensitive data in response to determining that the user not focusing on the one or more other portions of the displayed set of sensitive data. Apparatus and computer program products that can include, perform, and/or implement the methods are also provided.
