Abstract: A virtual machine (VM) is designated as a guarded VM so that restricted operations may not be performed on the VM without permission from the VM's owner. A request to perform at least one of the restricted operations on the VM is received. When the VM is a guarded VM, the request to perform at least one of the restricted operations on the VM is sent to the VM's owner. When the VM's owner at least partially approves the request, at least some of the restricted operations on the VM are enabled.

Abstract: A technique is described for managing processor (CPU) resources in a host having virtual machines (VMs) executed thereon. A target size of a VM is determined based on its demand and CPU entitlement. If the VM's current size exceeds the target size, the technique dynamically changes the size of a VM in the host by increasing or decreasing the number of virtual CPUs available to the VM. To “deactivate” virtual CPUs, a high-priority balloon thread is launched and pinned to one of the virtual CPUs targeted for deactivation, and the underlying hypervisor deschedules execution of the virtual CPU accordingly. To “activate” virtual CPUs and increase the number of virtual CPUs available to the VM, the launched balloon thread may be killed.

Abstract: A system and method for allocating resources receive one or more resource requests describing tasks, each of the one or more resource requests having a request priority, a requested configuration type, and a requestor identifier. In a winner-take-all circuit, all of the existing resource priorities within each configuration of the requested configuration type are compared to determine a highest-priority task occupying each assignment. In a loser-take-all circuit, one or more current highest resource priorities of each configuration within the requested configuration type, which are output from the winner-take-all circuit associated with the requested resource assignment, each of the one or more current resources having a current priority, are compared. One of the one or more current resource configurations within the requested configuration type having the lowest current priority is identified as the lowest-priority current resource configuration.

Abstract: Exemplary methods, apparatuses, and systems receive a first input/output (I/O) trace including storage addresses that were subject to a plurality of I/O requests from a first workload during a first period of time. The first I/O trace is run through a cache simulation using a plurality of simulated cache sizes. A first state of the cache simulation is stored upon completing the first I/O trace simulation. The first I/O trace is deleted in response to storing the first state. A second I/O trace including storage addresses that were subject to a plurality of I/O requests from the first workload during a second period of time is received. A cumulative miss ratio curve for the first workload is generated by loading the stored first state as a starting point for simulating the second I/O trace and running the second I/O trace through the cache simulation.

Abstract: In one embodiment, performance-based multi-mode task dispatching for high temperature avoidance in accordance with the present description, includes selecting processor cores as available to receive a dispatched task. Tasks are dispatched to a set of available processor cores for processing in a performance-based dispatching mode. If monitored temperature rises above a threshold temperature value, task dispatching logic switches to a thermal-based dispatching mode. If a monitored temperature falls below another threshold temperature value, dispatching logic switches back to the performance-based dispatching mode. If a monitored temperature of an individual processor core rises above a threshold temperature value, the processor core is redesignated as unavailable to receive a dispatched task. If the temperature of an individual processor core falls below another threshold temperature value, the processor core is redesignated as available to receive a dispatched task.

Abstract: A distributed work processing system for processing computational tasks is scalable and fault-tolerant without requiring centralized control. Worker processes running on worker hosts are organized into a logical group and worker coordinators running on worker coordinator hosts coordinate tasks assigned to worker processes. A task store might hold a collection of tasks to be performed by the logical group. A lock database can be used for locking the logical group for coordination by one worker coordinator process at a time. A membership store contains mappings of worker processes to logical groups, and an assignment store indicates which tasks are assigned to which workers. The worker coordinator process has a scanner process to deal with unassigned tasks and deduplicating duplicate assignments. If a worker coordinator does not see enough worker processes, it can instantiate more. If a worker process does not see a worker coordinator, it can instantiate one.
