Abstract: A streams manager monitors performance of a streaming application, and when the performance needs to be improved, the streams manager automatically requests virtual machines from a cloud manager. The cloud manager provisions one or more virtual machines in a cloud with the specified streams infrastructure and streams application components. The streams manager then modifies the flow graph so one or more portions of the streaming application are hosted by the virtual machines in the cloud. When performance of the streaming application indicates a virtual machine is no longer needed, the virtual machine is maintained and placed in a ready state so it can be quickly used as needed in the future without the overhead of deploying a new virtual machine.

Abstract: A transactional memory (TM) receives an Atomic Metering Command (AMC) across a bus from a processor. The command includes a memory address and a meter pair indicator value. In response to the AMC, the TM pulls an input value (IV). The TM uses the memory address to read a word including multiple credit values from a memory unit. Circuitry within the TM selects a pair of credit values, subtracts the IV from each of the pair of credit values thereby generating a pair of decremented credit values, compares the pair of decremented credit values with a threshold value, respectively, thereby generating a pair of indicator values, performs a lookup based upon the pair of indicator values and the meter pair indicator value, and outputs a selector value and a result value that represents a meter color. The selector value determines the credit values written back to the memory unit.

Abstract: Techniques for minimizing coprocessor “starvation,” and for effectively scheduling processing in a coprocessor for greater efficiency and power. A run list is provided allowing a coprocessor to switch from one task to the next, without waiting for CPU intervention. A method called “surface faulting” allows a coprocessor to fault at the beginning of a large task rather than somewhere in the middle of the task. DMA control instructions, namely a “fence,” a “trap” and a “enable/disable context switching,” can be inserted into a processing stream to cause a coprocessor to perform tasks that enhance coprocessor efficiency and power. These instructions can also be used to build high-level synchronization objects. Finally, a “flip” technique is described that can switch a base reference for a display from one location to another, thereby changing the entire display surface.

Abstract: In accordance with one aspect of the present description execution of a particular command by a data processor such as a storage controller, may include obtaining priority over a resource which is also associated with execution of another command, setting a timer for the duration of a dynamically set timeout period, and detecting a potential deadlock condition as a function of expiration of the dynamically set timeout period before execution of the particular command is completed. In one embodiment, the particular command releases priority over the resource upon detection of the potential deadlock condition, and then reobtains priority over the resource in a retry of the command. It is believed that such an arrangement can relieve a potential deadlock condition, allowing execution of one or more commands including the particular command to proceed. Other features and aspects may be realized, depending upon the particular application.

Abstract: A computer sequentially selects, when receiving a job execution request specifying the requested number of nodes, an axis from the n axes of n-dimensional space (n is an integer of two or greater) forming a network where nodes are connected by mesh or torus interconnect. The computer gradually extends the width of a temporary range of coordinates of the selected axis from a prescribed value, and determines, as a range for the selected axis, the temporary range where the number of available nodes whose coordinates on each defined axis having a determined range fall within the range and whose coordinates on the selected axis fall within the temporary range is greater than or equal to the requested number of nodes. After determining ranges for all the axes, the computer determines which nodes to assign to the job from available nodes whose coordinates on each axis fall within its range.
