Systems and methods for instant provisioning of virtual machine files
Embodiments of systems and methods are described for instant provisioning (e.g., cloning, copying, replicating, migrating, backing up, restoring, etc.) of virtual machines, virtual machine files, or other types of files (e.g., database files). In some implementations, a cloned virtual machine file can present an illusion to multiple applications accessing the cloned file that the cloned file contains all the appropriate data (e.g., a file system volume), even while the clone file is still being filled with relevant data. In some embodiments, the systems and methods use a file system filter driver to intercept and redirect certain input/output (I/O) requests to the cloned file. The file system filter driver may use a data structure (e.g., a bitmap) to determine which logical units of the clone file have already been filled with data. In some embodiments, the systems and methods use the operating system to handle cached I/O requests, which may improve efficiency. |

Method and apparatus for automatic diagnosis of software failures
One embodiment of the present invention provides a technique for automatic diagnosis of regression test failures. Initially, an automatic regression test system provides the test results per configuration for a revision of the device under test. Next, each failing test is analyzed in conjunction with the information in the version control system that is used to manage the device under test in order to conclude what additional revisions that needs to be tested for each test and configuration in order to find the earliest failing revision. Next, a request is issued to the automated regression test system which performs the requested tests and provides back a list of test results. Next, another analysis takes places and if the earliest failing revision cannot be concluded for each failing test and configuration then another request is issues to the automated regression test system. This continues until the earliest failing revision can be concluded for each failing test and configuration. The result presents each faulty revision and the group of tests and configurations that fail as a consequence. Another embodiment of the present invention provides a technique for automatically diagnosing the root cause for a test failure by comparing the difference in outcome between one revision of the device under test that fails with another revision of the same test for which the same test passes. This is done by instrumenting the computer program that constitutes the device under test to extract the variable states that affect the difference in outcome. Next, all parts of the computer program that are proven to have no affect on the difference in outcome is ignored. Finally, the root cause is concluded by identifying the sections of the computer program that are different between the revision for which the test fails and the revision for which test passes. The parts of these sections that have also been proven to be affecting the difference in outcome are concluded to be the root cause. |

Writeback mechanisms for improving far memory utilization in multi-level memory architectures
Multi-level memory architecture technologies are described. One processor includes a requesting unit, a first memory interface to couple to a far memory (FM), a second memory interface to couple to a near memory (NM) and a multi-level memory controller (MLMC) coupled to the requesting unit, the first memory interface and the second memory interface. The MLMC is to write data into a memory page of NM in response to a request from the requesting unit to retrieve the memory page from FM. The MLMC receives a hint from the requesting unit and clears a writeback bit for the memory page indicated in the hint. The hint indicates that the data contained in the memory page of the NM is not to be subsequently requested by the requesting unit. The MLMC starts a writeback operation of a memory sector including the memory page and one or more additional memory pages. The writeback operation is to transfer the data contained in the memory page from the NM to the FM when the writeback bit is set and the writeback operation does is not to transfer the data contained in the memory page from NM to the FM when the writeback bit is cleared. |

Fast link establishment for network access
A communication session between a node seeking network access and a NAS (Network Access Server) is established by having only few exchanges of messages.

Code regeneration determination from selected metadata fingerprints
A fingerprint is computed from selected metadata of binary files, and used in determining whether to regenerate code-behind file(s). In one case, after ascertaining that a binary-file-set's current metadata-fingerprint differs from a previous metadata-fingerprint, the corresponding code-behind-file-set is regenerated. A code-behind file may also be regenerated, even though its current fingerprint matches its previous fingerprint, because its metadata has changed. If the current fingerprint matches the previous fingerprint and metadata is unchanged, regeneration can be avoided. The fingerprint may consist of, or merely contain, definitions of classes, properties, and other items, and may be limited to metadata that is used when generating the code-behind-file-set. System assemblies are not fingerprinted. Timestamps may be used. Metadata-fingerprint computation code and regeneration determination code are described. Metadata-fingerprints may be used in developing applications with web-based application code frameworks, frameworks having code for rendering a user interface, other frameworks, XAML, C#, and other programming languages. |

The optical resonator (100) includes an optical cavity (102) and an optical element (104.1, 104.2) at either end thereof, operable to sustain a light beam (108) therein, characterized in that each optical element (104.1, 104.2) is a phase-only optical element operable to alter a mode of the beam (108) as it propagates along the length of the optical resonator (100), such that in use the beam (108) at one end of the optical resonator (100) has a Gaussian profile while the beam (108) at the other end of the optical resonator (100) has a non-Gaussian profile. |

Echelle diffraction grating and its manufacturing method, excimer laser and its manufacturing method
A manufacturing method for an excimer laser that includes a reflective Echelle diffraction grating includes obtaining information of a wavelength of a light source, a blazed order, a repetitive pitch of the grating, a material of the grating, and a predefined orientation ratio B/A that is a ratio between that a diffraction efficiency A of the blazed order and a diffraction efficiency Bb of an order lower by one order than the blazed order, and determining an initial value of a blaze angle based upon these pieces of information. |

Low inductance laser diode bar mount
The laser mount arrangement can have a laser bar and a driver positioned adjacent to one another and secured against a connection face of a heat sink base. The heat sink base is connected to and forms a first electrical connection between the laser bar and the driver. A second electrical connection is also provided between the laser bar and the driver opposite the heat sink base, which can be in the form of a flexible metal sheet with a narrow upward fold. This arrangement can provide a low inductance path for the current. |
