In-place recovery of fatal system errors at virtualization hosts. A device identifies an occurrence of a fatal system error in the first instance of a host operating system (OS) executing in a computer system. The device determines to perform an in-place recovery for the fatal system error. The device performs the in-place recovery, including pausing the execution of a virtual machine (VM) by the first instance of the host OS, preserving a state of the VM within system memory of the computer system, and resuming the execution of the VM by a second instance of the host OS executing in the computer system based on the state of the VM that is preserved within the system memory of the computer system.

In-place recovery of fatal system errors at virtualization hosts

Embodiments of the present invention relate to systems, methods, and computer storage media for concurrently maintaining a spanned virtual hard drive across two or more computer-storage media and a non-spanned virtual hard drive on one of computer-storage media. The method includes storing data of the spanned virtual hard drive across the computer-storage media utilizing volume spanning. While the spanned virtual hard drive is maintained on the computer storage media, the method includes storing data of the non-spanned virtual hard drive on one of the computer-storage media.

Isolation of virtual machine I/O in multi-disk hosts

Described herein are techniques pertaining to real-time propagation of an arbitrary audio signal in a fixed virtual environment with dynamic audio sources and receivers. A wave-based numerical simulator is configured to compute response signals in the virtual environment with respect to a sample signal at various source and receiver locations. The response signals are compressed and placed in the frequency domain to generate frequency responses. Such frequency responses are selectively convolved with the arbitrary audio signal to allow real-time propagation with moving sources and receivers in the virtual environment.

Real-time sound propagation for dynamic sources

Described is a technology for use with general discrete Fourier transforms (DFTs) performed on a graphics processing unit (GPU). The technology is implemented in a general library accessed through GPU-independent APIs. The library handles complex and real data of any size, including for non-power-of-two data sizes. In one implementation, the radix-2 Stockham formulation of the fast Fourier transform (FFT) is used to avoid computationally expensive bit reversals. For non-power of two data sizes, a Bluestein z-chirp algorithm may be used.

Fast computation of general fourier transforms on graphics processing units

A paint simulation system described herein includes a brush component that outputs a three-dimensional computer-implemented model of an image editing tool. A paint component receives the three-dimensional computer-implemented model and generates a two-dimensional map corresponding to a footprint of the three-dimensional model with respect to a computer-implemented canvas, wherein resolution of the two-dimensional map is substantially similar to resolution of a paint map of the computer-implemented canvas.
