摘要： An engine (TOE) is provided in a virtualized computer system for offloading I/O tasks using any defined protocol such as TCP/IP. The system includes a virtual machine (VM), which has a guest operating system (OS) that runs via a virtual machine monitor (VMM) on a system-level software platform (vmkernel), which also forms the software interface layer to at least one physical network connection device. A TCP/IP stack is included in vmkernel. During normal I/O operation, for sockets associated with TOE, processes in an application layer in the guest OS are able to communicate directly with vmkernel's TCP/IP stack, thereby bypassing the guest OS kernel.

摘要： A virtualization platform provides fault tolerance for a primary virtual machine by continuously transmitting checkpoint information of the primary virtual machine to a collector process, such as a backup virtual machine. When implemented on a hardware platform comprising a multi-processor that supports nested page tables, the virtualization platform leverages the nested page table support to quickly identify memory pages that have been modified between checkpoints. The backup virtual machine provides feedback information to assist the virtualization platform in identifying candidate memory pages for transmitting actual modifications to the memory pages rather than the entire memory page as part of the checkpoint information. The virtualization platform further maintains a modification history data structure to identify memory pages that can be transmitted simultaneous with the execution of the primary virtual machine rather than while the primary virtual machine has been stunned.

摘要： Methods for providing pharmaceutical compositions and objects with identification regions and identification features which are difficult to detect. Microlithography, nanolithography, and stamping methods are used. The identification features can be positive protrusions or negative indentations with respect to the surface. The identification regions can comprise bar codes and holograms. DPN printing or other lithographies such as electron beam lithography, optical lithography, or nanoimprint lithography can be used to prepare stamps, which are then used to prepare the identification features. Redundant patterns can be formed. The invention is useful for counterfeit prevention. An apparatus for stamping the identification features is also described.

摘要： A system and method for aligning prior patterning positions formed by a first SPM tip with a second SPM tip in combination with an SPM system includes identifying first location information that includes a location of the first SPM tip and a sample reference location on an SPM sample and storing the first location information in a storage area. After replacing the first SPM tip with the second SPM tip, second location information, which includes a location of the second SPM tip and the sample reference location on the SPM sample, is identified. Displacement is calculated between the location of the second SPM tip and the first SPM tip based on the first and second location information, and either the second SPM tip or a stage supporting the SPM sample is translated to align the second SPM tip with the location of the first SPM tip in accordance with the calculated displacement.

摘要： Inkwells adapted for use in direct-write nanolithography and other applications including use of wells, channels, and posts. The wells can possess a geometry which matches the geometry of tips which are dipped into the inkwells. The channels can be open or closed. Hydrophilicity and hydrophobicity can be used to control ink flow. SEM can be used to characterize the inkwells. Ink flow can be monitored with video. Hydrophobic material layers can be used to prevent cross contamination. Microsyringes can be used to fill reservoirs. Satellite reservoirs can be used to prevent bubble formation.
