Block allocation for low latency file systems
An LL server (LLS) may process metadata requests for a file system in LL mode in a distributed file storage services (DFSS). For requests that require allocating blocks to file system objects in the backing store, instead of relying on distributed transactions used for file systems in high throughput (HT) mode, a pool of blocks may be pre-allocated for the LL file system in the backing store, and a free block list may be maintained in local memory of the LLS. When a metadata operation requires blocks to be allocated, the blocks are assigned to the respective object from the blocks in the pool. A background process may allocate new blocks in the pool upon the number of blocks dropping below a threshold, or upon block allocation rate for the file system increasing. |

Early virtualization context switch for virtualized accelerated processing device
A technique for efficient time-division of resources in a virtualized accelerated processing device (“APD”) is provided. In a virtualization scheme implemented on the APD, different virtual machines are assigned different “time-slices” in which to use the APD. When a time-slice expires, the APD performs a virtualization context switch by stopping operations for a current virtual machine (“VM”) and starting operations for another VM. Typically, each VM is assigned a fixed length of time, after which a virtualization context switch is performed. This fixed length of time can lead to inefficiencies. Therefore, in some situations, in response to a VM having no more work to perform on the APD and the APD being idle, a virtualization context switch is performed “early.” This virtualization context switch is “early” in the sense that the virtualization context switch is performed before the fixed length of time for the time-slice expires. |

Multiple-view compressed-sensing ultrafast photography (MV-CUP)
A system and method for compressed-sensing ultrafast photography for two-dimensional dynamic imaging is disclosed. The system and method may capture non-repetitive time-evolving events at up to about 100 billion frames per second.In an aspect, a digital micromirror device (DMD) may be added as the spatial encoding module. By using the DMD and applying the CUP reconstruction algorithm, a conventional 1D streak camera may be transformed to a 2D ultrafast imaging device. The resultant system may capture a single, non-repetitive event at up to 100 billion frames per second with appreciable sequence depths (up to about 350 frames per acquisition). In another aspect, a dichroic mirror may be used to separate signals into two color channels, and may further expand CUP's functionality into the realm of four-dimensional x, y, λ, t ultrafast imaging, maximizing the information content that may be simultaneously acquired from a single instrument.On the basis of compressed sensing (CS), CUP may encode the spatial domain with a pseudo-random binary pattern, followed by a shearing operation in the temporal domain, performed using a streak camera with a fully opened entrance slit. This encoded, sheared three-dimensional (3D) x, y, t scene may then be measured by a 2D detector array, such as a CCD, within a single snapshot. The image reconstruction process follows a strategy similar to CS-based image restoration—iteratively estimating a solution that minimizes an objective function. However, unlike CS-based image restoration algorithms, which target the reconstruction of a 2D x, y image, CUP reconstruction recovers a 3D x, y, t movie by applying regularization over both the spatial domain and the temporal domain. |
