Methods, systems, and computer readable media for emulating virtualization resources are disclosed. According to one method, the method occurs at a computing platform. The method includes receiving a message associated with a device under test (DUT) and in response to receiving the message, performing an action associated with at least one of an emulated hypervisor and an emulated virtual machine (VM).

Various embodiments for regulating link speed for performance enhancement and port diagnosis are provided. In response to identifying an amount of errors in a communications link above a predetermined threshold, an applicable transmission speed is selectively reduced. If errors identified at the reduced transmission speed are found to decrease, a communications port incorporating the communications link is flagged as potentially dirty, and if the errors identified at the reduced transmission speed are found to remain constant, the communications port is flagged as potentially bad.

Examples relate to firmware-based provisioning of hardware resources. In some of the examples, firmware discovers and takes ownership of a hardware resource. At this stage, the firmware performs a test to verify the hardware resource. The firmware then assigns the hardware resource to an OS instance. At this stage, the firmware can suspend assigning further hardware resources to the OS instance in response to a satisfied notification from the OS instance.

According to one embodiment, in a case where a test on an encryption device indicates an error in an encryption process of the encryption device, a data processing device holds a result of the test on the encryption device in a holding unit, and notifies that the encryption device has an error on the basis of the result of the test on the encryption device.

A method for testing a technical system. The method includes: tests are carried out with the aid of a simulation of the system, the tests are evaluated with respect to a fulfillment measure of a quantitative requirement on the system and an error measure of the simulation, on the basis of the fulfillment measure and error measure, a classification of the tests as either reliable or unreliable is carried out.

A method and associated systems for optimizing a computing platform. A processor joins sets of configurable parameters into groups that each identifies a configuration of the computing environment or of a component or subsystem of the computing environment. The processor generates a set of variations of each group, where each variation identifies a candidate configuration of the component, subsystem, or platform, and where each candidate configuration identifies a distinct set of values of the group of parameters associated with that component, subsystem, or platform. Each configuration of this first generation of configurations undergoes a massively parallel iterative procedure that generates a next generation of configurations by performing operations upon the first generation that are similar to those of a natural-selection process. The procedure repeats until successive generations converge, within resource constraints, to a fittest generation that represents an optimal or most nearly optimal configuration of the computing platform.

Examples of techniques for routing a representational state transfer (REST) request among a plurality of virtual processing systems are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method may include: receiving, at a load balancer, the REST request; assigning, by the load balancer, the REST request to one of a plurality of web servers, each of the plurality of web servers executing on a virtual processing system; routing, by the one of the plurality of web servers, the REST request to one of the plurality of virtual processing systems; and storing, by the one of the plurality of web servers, state information regarding the REST request to a data store.

A system is provided for determining causes of faults in a manufacturing system. The system stores data associated with a processing system which includes machines and associated processes, wherein the data includes timestamp information, machine status information, and product-batch information. The system determines, based on the data, a topology of the processing system, wherein the topology indicates flows of outputs between the machines as part of the processes. The system determines information of machine faults in association with the topology. The system generates, based on the machine-fault information, one or more fault parameters which indicates frequency and severity of a respective fault. The system constructs, based on the topology and the machine-fault information, a system model which includes the one or more fault parameters, thereby facilitating diagnosis of the processing system.
