Abstract: Systems and techniques are described for modifying an executable file of an application and executing the application using the modified executable file. A described technique includes receiving, by a virtual machine, a request to perform an initial function of an application and an executable file for the application. The virtual machine modifies the executable file by redirecting the executable file to a custom runtime library that includes a custom function configured to initialize the application and to place the application in a paused state. A custom function call is added to the custom function in the executable file. The virtual machine initializes the application by executing the modified executable file, the executing causing the custom function to initialize the application and place the application in a paused state.

Abstract: Various aspects are disclosed for graphics processing unit (GPU)-remoting latency aware migration. In some aspects, a host executes a GPU-remoting client that includes a GPU workload. GPU-remoting latencies are identified for hosts of a cluster. A destination host is identified based on having a lower GPU-remoting latency than the host currently executing the GPU-remoting client. The GPU-remoting client is migrated from its current host to the destination host.

Abstract: The current document is directed to methods and systems that employ image-recognition and machine learning to directly measure application-program response time from changes in a user interface displayed by the application program in much the same way that application-program users perceive response times when manually issuing commands through the user interface. The currently disclosed methods and systems involve building recognition models, training the recognition models to recognize application-program states from changes in the user interface displayed by the application program, and using the recognition models to monitor the user interface displayed by an application program to detect and assign timestamps to application-program state changes, from which the elapsed time for various different operations is computed. This approach mirrors the methods by which users perceive application-program response time when users initiate operations through the application-program-provided user interface and visually monitor progress of the operations as reflected in changes to the displayed application-program user interface.

Abstract: Various examples are disclosed for avoiding power-on failures during virtualization of graphics processing units. A computing environment can be directed to, in response to a virtual machine being powered on, identify a profile for a virtual graphics processing unit (vGPU) designated for the virtual machine, the profile specifying an amount of memory required by the vGPU, identify that the virtual machine is unable to be assigned to any of a plurality of physical graphics processing units (GPUs) based on the amount of memory required by the vGPU, free fat least the amount of memory required by the vGPU by performing a migration of at least one existing virtual machine from a first one of the physical GPUs to a second one of the physical GPUs, and assign the virtual machine to an available one of the physical GPUs and a corresponding host.

Abstract: Disclosed are aspects of memory-aware placement in systems that include graphics processing units (GPUs) that are virtual GPU (vGPU) enabled. In some examples, graphics processing units (GPU) are identified in a computing environment. Graphics processing requests are received. A graphics processing request includes a GPU memory requirement. The graphics processing requests are processed using a graphics processing request placement model that minimizes a number of utilized GPUs that are utilized to accommodate the requests. Virtual GPUs (vGPUs) are created to accommodate the graphics processing requests according to the graphics processing request placement model. The utilized GPUs divide their GPU memories to provide a subset of the plurality of vGPUs.

Abstract: Disclosed are various embodiments for rate proportional scheduling to reduce packet loss in virtualized network function chains. A congestion monitor executed by a first virtual machine executed by a host computing device can detect congestion in a receive queue associated with a first virtualized network function implemented by a first virtual machine. The congestion monitor can send a pause signal to a rate controller executed by a second virtual machine executed by the host computing device. The rate controller can receive the pause signal. In response, the rate controller can pause the processing of packets by a second virtualized network function implemented by the second virtual machine to reduce congestion in the receive queue of the first virtualized network function.
