Abstract: Various embodiments provide a method and apparatus of providing a rapid disaster recovery preparation in cloud networks that proactively detects disaster events and rapidly allocates cloud resources. Rapid disaster recovery preparation may shorten the recovery time objective (RTO) by proactively growing capacity on the recovery application(s)/resource(s) before the surge of recovery traffic hits the recovery application(s)/resource(s). Furthermore, rapid disaster recovery preparation may shorten RTO by growing capacity more rapidly than during “normal operation” where the capacity is increased by modest growth after the load has exceeded a utilization threshold for a period of time.

Abstract: A data processing apparatus has error detection units each configured to generate an error signal if a first and second sample of a signal associated with execution of an instruction differ. Error value generation circuitry generates an error value showing if any of the error detection units have generated the error signal. Error value stabilisation circuitry performs a stabilisation procedure comprising re-sampling the error value to remove metastability. Error recovery circuitry initiates re-execution of the instruction if the error value is asserted. Count circuitry holds a counter value in association with the error value, the counter value set to a predetermined value when the error value is generated and decremented each time the error value is re-sampled prior to reaching the error value stabilisation circuitry. The error value bypasses the stabilisation procedure if the counter value is zero before the error value reaches the error value stabilisation circuitry.

Abstract: A stream application may allocate processing elements to one or more compute nodes (or hosts) to achieve a desired optimization goal. Each optimization mode may define processing element selection criteria and/or host selection criteria. When allocating a processing element to a host, a scheduler may place each processing element individually.

If the scheduler determines that multiple hosts are suitable candidates for the processing element, it may use the host selection criteria to pick one of the candidate hosts that further optimize the stream application to meet the desired goal.
