Embodiments of the present invention provide a method, system and computer program product for collaborative route reservation in an HPC fabric. A method for collaborative route reservation in an HPC fabric includes selecting a target node in a cluster of nodes to receive a payload from a source node of the cluster over an HPC fabric and computing a route over the HPC fabric for transferring the payload from the source node to the target node, and also a duration of time requisite to transferring the payload. The method also includes notifying other nodes in the cluster of a reservation of the computed route for the duration of time and utilizing the computed route during the duration of time to transfer the payload. Finally, the method includes responding to completing transfer of the payload by notifying the other nodes that the computed path is no longer reserved.

Embodiments of the present invention disclose a method, computer program product, and for determining a recommendation relating to a configuration of a plurality of server nodes of a computing system. In one embodiment, in accordance with the present invention, the computer implemented method includes the steps of, for each server node, storing a first performance parameter value, wherein each first performance parameter value is a benchmarked value that corresponds to a measured actual performance parameter of its associated server node, and applying a first configuration rule based, at least in part, on the first performance parameter values of the plurality of server nodes to obtain a first configuration recommendation. In another embodiment, the method further includes the step of presenting the first recommendation to a human user.

Positioning autonomous vehicles based on field of view, including: identifying, by a vehicle management module, one or more critical sight lines for a subject vehicle, each critical sight line representing a boundary of an area of space surrounding the subject vehicle; determining, by the vehicle management module, physical location information for one or more surrounding vehicles; determining, by the vehicle management module in dependence upon the physical location information for one or more surrounding vehicles, whether one or more surrounding vehicles are located within the area of space surrounding the subject vehicle; and responsive to determining that one or more surrounding vehicles are located within the area of space surrounding the subject vehicle, altering a location of the subject vehicle relative to at least one of the surrounding vehicles.

Method of cooperative reduced power mode suspension for high input/output ('I/O') workloads, including: determining, by a transfer monitoring module, a size of a file to be transferred to a recipient, wherein the recipient includes a central processing unit ('CPU') operating in a reduced power mode; determining, by the transfer monitoring module, a desired transfer rate for transferring the file to the recipient; calculating, by the transfer monitoring module, an expected transfer completion time in dependence upon the size of the file and the desired transfer rate; and sending, by the transfer monitoring module, a message to the recipient requesting that the CPU suspend the reduced power mode in dependence upon the expected transfer completion time.
