Abstract: For example, a compiler may be configured to identify a select instruction in a loop operation based on a source code, the select instruction to select between a first value and a second value according to a mask in the select instruction: to configure a masked operation in the loop operation based on the select instruction, wherein the masked operation is based on the mask in the select instruction, the masked operation including a passthrough value based on the second value; and to generate target code based on compilation of the source code, wherein the target code is based on the masked operation.

Abstract: A method includes: receiving input code that comprises a loop that operates on a first array of elements and a second array of elements, wherein during an iteration of the loop a first operation is performed on an element of the first array of elements, or a second operation is performed on an element of the second array of elements; generating a first compound operation that operates on a predetermined number of elements of the first array of elements, the first compound operation resulting in a first intermediate vector; generating a second compound operation that operates on the predetermined number of elements of the second array of elements, the second compound operation resulting in a second intermediate vector; interleaving the first intermediate vector and the second intermediate vector and storing the interleaved result in a temporary vector; and summing the interleaved result in the temporary vector using an order-preserving sum.

Abstract: Machines, systems and methods for managing resources allocated in a virtualized computing network are provided. The method comprises monitoring resource usage by a first host, wherein the first host, in addition to the first host's dedicated resources, has access to a first set of sharable resources, and wherein the second host, in addition to the second host's dedicated resources, has access to a second set of sharable resources; determining whether the second host has excess resource capacity in the second host's dedicated and sharable resources, in response to determining that resource usage of the first host in the first host's dedicated and sharable resources has exceeded a resource usage threshold; and reallocating one or more resources in the second set of sharable resources from the second host to the first host, in response to determining that the second host has excess resource capacity.

Abstract: Systems and methods for scheduling events in a virtualized computing environment are provided. In one embodiment, the method comprises scheduling one or more events in a first event queue implemented in a computing environment, in response to determining that number of events in the first event queue is greater than a first threshold value, wherein the first event queue comprises a first set of events received for purpose of scheduling, wherein said first set of events remain unscheduled; mapping the one or more events in the first event queue to one or more server resources in a virtualized computing environment; receiving a second set of events included in a second event queue, wherein one more events in the second set of event are defined as having a higher priority than one or more events in the first event queue that have or have not yet been scheduled.

Abstract: A method, apparatus, and computer program product for monitoring operation of data processing resources in a data processing environment. A request to monitor a service instance may be received by a processor unit, wherein the service instance comprises a data processing resource provided as a service by a provider of the data processing resources. Responsive to receiving the request to monitor the service instance, the processor unit establishes communications to receive monitored data from the service instance. The processor unit receives the monitored data from the service instance and provides the monitored data to a monitoring infrastructure, wherein the monitoring infrastructure is configured to monitor operation of the data processing resources.
