Appl. No.:

10/295554

Inventors:

Magnus Karlsson - Mountain View CA, US
Qian Wang - State College PA, US
John Wilkes - Palo Alto CA, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 11/00

US Classification:

714 4, 709201

Abstract:

A technique for data placement in a distributed system that takes into account fault tolerance. Data placement is performed in which data objects, and possibly replicas thereof, are assigned to nodes within the distributed system. The resulting placement is then tested to determine whether the system provides desired performance under various different fault scenarios. If not, the distributed system is altered such as by altering its capacity or its capacity allocations. Performing data placement, testing for fault-tolerance and altering capacity or capacity allocations are performed repetitively, thereby increasing the system's ability to provide the desired performance under the fault scenarios. Preferably, a system and placement are eventually determined that provide the desired performance under the given fault scenarios.

International Classification:

H01L027/14

US Classification:

257414000

Abstract:

A carbon nanotube is formed on at least one Molybdenum-based electrode. In one embodiment, a carbon-nanotube device includes a pair of Molybdenum-based electrodes over respective terraces. Using a catalyst on the Molybdenum-based material of at least one electrode, a carbon nanotube is grown over a gap that separates the terraces to connect the Molybdenum-based electrodes. Yet other aspects of the present invention employ carbon nanotubes extending (suspended) from respective Molybdenum-based structures for use in electrically addressable devices. The nanotubes can also be formed by patterned growth to bridge such Molybdenum-based electrodes. A particular method for manufacturing this device does not require post-growth processing. Applications include, among many others, scalable nanotube transistors/switches nano-electromechanical systems.

Abstract:

Compositions and methods are provided for preventing or treating the pre-clinical early-stages of inflammatory diseases, including autoimmune diseases, degenerative inflammatory diseases, metabolic inflammatory diseases, chronic infection associated with inflammation, cancer associated with inflammation, and other inflammatory diseases by administration to an individual of an effective dose of a synergistic combination of active agents comprising or consisting essentially of an aminoquinoline, e.g. hydroxychloroquine, and a statin, e.g. atorvastatin. Each or both of the active agents can be formulated in various ways, including without limitation a solid oral dosage form.

International Classification:

G06F 12/0802

Abstract:

The disclosure relates to technology for up-evicting cache lines. An apparatus comprises a hierarchy of caches comprising a first cache having a first cache controller and a second cache having a second cache controller. The first cache controller is configured to store cache lines evicted from a first processor group to the first cache and to down-evict cache lines from the first cache to the second cache. The second cache controller is configured to store cache lines evicted from a second processor group into the second cache, to up-evict a first cache line from the second cache to the first cache in response to an eviction of a second cache line from the second processor group to the second cache, and to provide the up-evicted first cache line from the first cache to the second processor group in response to a request from the second processor group.

H01L 23/29

Abstract:

A release layer is formed on a surface of an integrated circuit wafer. The surface is passivated and includes metal contact materials. A stress-engineered film having an intrinsic stress profile is deposited over the release layer. The stress-engineered film is patterned and the release layer is undercut etched so that a released portion of the patterned stress-engineered film is released from the surface while leaving an anchor portion fixed to the surface. The intrinsic stress profile in the stress-engineered film biases the released portion away from the surface. The released portion is placed entirely within an area defined by the metal contact material.

H01L 23/00

Abstract:

An electronic assembly and methods of making the assembly are disclosed. The electronic assembly includes a substrate with an elastic member having an intrinsic stress profile. The elastic member has an anchor portion on the surface of the substrate; and a free end biased away from the substrate via the intrinsic stress profile to form an out of plane structure. The substrate includes one or more spacers on the substrate. The electronic assembly includes a chip comprising contact pads. The out of plane structure on the substrate touches corresponding contact pads on the chip, and the spacers on the substrate touch the chip forming a gap between the substrate and the chip.
