Abstract: A redundant array of independent disk (RAID) stack loads a first parity block of RAID data into a first memory address of a main memory of a data processing system. A first parity calculation is performed on a first plurality of data blocks of the RAID data with the first parity block loaded from the first memory address of the main memory into a register of the processor of the data processing system and a cache memory associated with the processor. The RAID stack loads subsequent parity blocks of RAID data into subsequent memory addresses of the main memory, where a difference between the first memory address and the subsequent memory addresses equals to one or more multiples of an alias offset associated with the cache memory. A second parity calculation is performed on a second plurality of data blocks and the second parity block of the RAID data.

Abstract: A method for the separation of particles of different densities using a step-wise gradient density extraction method as described herein where a sample is suspended in a liquid volume of an extracting medium of specific density and the particles that have a density less than or equal to that of the extracting medium of specific density can be recovered from a horizonatally rotatable hollow disk or a removable receptacle within a horizontally rotatable hollow disk designed for such purposes while the particles that have a density greater than the extracting medium of specific density form a deposit which can be cycled through the extraction process in an iterative fashion by varying the density of the extracting medium allowing the recovery of discrete particles of differing densities from a test sample.

Abstract: A set of 2D reconstructed images is generated from a pretreatment 3D scan showing an initial position of a target, wherein the set of 2D reconstructed images corresponds to perturbations from said initial position along fewer than six degrees of freedom. Said set of 2D reconstructed images are registered with one or more 2D x-ray images of said target showing a current position of the target, wherein the registering includes computing a set of 3D transformation parameters that represent a change in position of said target between said initial position of said pretreatment 3D scan and said current position of said 2D x-ray images along six degrees of freedom. A positioning system is instructed to adjust a relative position of a radiosurgical beam generator to said target by an amount prescribed by said 3D transformation parameters, wherein said target is allowed six degrees of freedom of position.

Abstract: Dictionary-based sequential compression is performed in parallel on input data using multiple cores of a computer system. The compression can be performed by first determining a dictionary size for data compression, followed by determining a block size for partitioning the input data. The block size is greater than the dictionary size. The multiple cores of the computer system then execute multiple threads in parallel, with each thread compressing one block of the input data according to a dictionary-based sequential compression scheme.

Abstract: Techniques for automatically providing a client with access to a virtual machine associated with the client are described herein. According to one embodiment, a message is received by a controller from a client over a network indicating that the client is starting up. In response, the controller causes a connection to be automatically established between the client and a virtual machine (VM) associated with the client once the client has started up. The associated VM may be one of a predetermined VM, a member of a group of VMs that are associated with the client, and a VM selected from a pool of VMs. As a result, a user of the client can instantly access contents provided by the associated VM without having to manually log onto a Web portal in order to select the associated VM to be launched. Other methods and apparatuses are also described.

Abstract: Techniques for improving cache accesses in an object-relational mapping space are described herein. In one embodiment, in response to a first cache request received at a first cache API associated with a transaction for updating a data entry of the relational database, the updated data of the data entry is stored in a local cache, where the local cache is one of members of a cache cluster, and an invalidation message is sent to remaining members of the cache cluster to invalidate corresponding cache entries of the remaining members. In response to a second cache request received at a second cache API associated with a transaction for loading data from a data entry of the relational database, the loaded data is stored in the local cache without sending an invalidation message to the remaining members of the cache cluster. Other methods and apparatuses are also described.

Abstract: Embodiments of the present invention provide methods and systems for certifying components based on certification of the development and testing processes of the components. As noted above, traditional certification relies on the certification service or agent to specify the exact details of the development and testing processes performed on a component. In contrast, embodiments of the present invention rely on determining a standard required that should be satisfied by the processes performed on the component and certifying those processes that meet this standard. Hence, detailed specification of the individual actions performed in certified processes is unnecessary. This allows the various entities that develop or test (i.e., produce) a component to flexibly determine their own processes.

Abstract: A security initialization system receives a first initialization request from a first requester to access a first database storing security data and stores context data for the first initialization request that identifies an initialization operation associated with the first database. The security initialization system receives a second initialization request from a second requester to access a second database storing security data and updates the context data to identify an initialization operation associated with the second database. The security initialization system receives a shut down request from one of the requesters, where the shut down request includes data for identifying a corresponding initialization operation in the context data. The security initialization system updates the context data to show that the corresponding initialization operation has a shut down request and determines whether a security module is to be shut down using the context data.
