Abstract: A new approach is proposed virtual machines (VMs) accessing remote storage devices over a network via non-volatile memory express (NVMe) controllers to migrate live from a current host to a destination host. A first virtual NVMe controller running on a first physical NVMe controller enables a first VM running on the current host to perform storage operations to logical volumes mapped to the remote storage devices over the network as if they were local storage volumes. During VM migration, the current host puts the first virtual NVMe controller into quiesce state and saves an image of its states. A second virtual NVMe controller is created on a second physical NVMe controller using the saved image, which is configured to serve a second VM on the destination host. The second virtual NVMe controller resumes the storage operations to the remote storage devices without being interrupted by the VM migration.

Abstract: A method (which can be computer implemented) for inferring whether at least a first relationship exists between at least first and second entities includes the steps of applying a first assessor to obtain a first confidence level pertaining to putative existence of said at least first relationship between said at least first and second entities, applying a second assessor to obtain a second confidence level pertaining to putative existence of said at least first relationship between said at least first and second entities, and combining said first and second confidence levels to obtain an overall inference whether said at least first relationship exists between said at least first and second entities.

Abstract: A method for operating a lock in a computing system having plural processing units and running under multiple runtime environments is provided. When a requester thread attempts to acquire the lock while the lock is held by a holder thread, determine whether the holder thread is suspendable or non-suspendable. If the holder thread is non-suspendable, put the requester thread in a spin state regardless of whether the requester thread is suspendable or non-suspendable; otherwise determines whether the requester thread is suspendable or non-suspendable unless the requester thread quits acquiring the lock. If the requester thread is non-suspendable, arrange the requester thread to attempt acquiring the lock again; otherwise add the requester thread to a wait queue as an additional suspended thread. Suspended threads stored in the wait queue are allowable to be resumed later for lock acquisition. The method is applicable for the computing system with a multicore processor.

Abstract: Facilitating single sign-on (SSO) across multiple browser instances such that user authentication at one browser instance is used as a basis to permit access to protected resources (hosted on server systems) from other browser instances. In an embodiment, the different browser instances are executing on different client systems. An authentication server may maintain a registration data indicating the different client systems/browser instances registered by a user for SSO feature. After a user is authenticated for a first session from one browser instance, the authentication server enables the user to access any protected resource from registered client systems/browser instances without requiring further authentication (based on the presence of the authenticated first session).

Abstract: Methods, apparatus, and computer readable media with executable instructions stored thereon for virtual machine placement are provided. A user's demands on execution of a number of tasks, each task including a demand trace, can be defined as Service Level Agreement (SLA) information, including one or more Class of Service (CoS) levels defined by a Base Resource Entitlement (BRE) criteria and a Reserved Resource Entitlement (RRE) criteria (222). A highest CoS level of the one or more CoS levels can be selected (224) and the tasks within the Cos level can be load-balanced across a pool of servers (226). At least a portion of the RRE criteria can be removed from the demand trace of the selected CoS level (228). The selecting, load-balancing, and removing steps can be repeated until there are no more CoS levels (230).

Abstract: A system and computer-implemented method for providing access to data of a first party including receiving information for identifying the first party, authenticating the first party using the received information for identifying the first party and generating a first read-only personal identification number (PIN). The first read-only PIN is associated with a first set of access rights for the data of the first party and provided to a second party. The first read-only PIN is stored with the first set of access rights in a computer database. A third party receives the first read-only PIN from the second party, authenticates the received first read-only PIN using the stored first read-only PIN and provides the second party with access to at least a portion of the data of the first party using the first set of access rights associated with the first read-only PIN if the received first read-only PIN is authenticated.

Abstract: Methods and system for optimizing an execution of a business process are disclosed. In one aspect, a request to execute a business process is received. The business process is executed on multiple threads, which may include multiple computations. The business process is optimized by determining an optimal number of threads for executing the business process by a thread optimization model. From the determined optimal number of threads, the computations in the threads may be distributed or reallocated iteratively by executing an inter-thread computations optimization model. Executing the thread optimization model and the inter-thread computations optimization model optimizes the execution of the business process.

Abstract: A system and method for classifying comments are disclosed. The method includes receiving a collection of comments. Each of the comments in the collection includes text in a natural language and is associated with a previously-submitted idea submission which includes a description of an idea. The method further includes natural language processing each of the comments to identify dependencies (syntactic and/or semantic relations between text elements) in at least a part of the comment. Based on the identified dependencies, the comments are each automatically classified into one (or more) of a plurality of comment classes. The comment classes may include a first class for reaction to the content of the idea, a second class for expression of a commenter's judgment of an idea's value, and a third class for reaction to an idea generation process in which the associated idea submission is made. Information based on the assigned comment classes is output.

Abstract: An apparatus for calculating a result of a scalar multiplication of a reference number with a reference point on an elliptic curve includes a random number generator and processor. The random number generator generates a random bit. The processor calculates the result of the scalar multiplication based on a calculation algorithm using a first auxiliary variable storing a first interim result representing an integer multiple of the reference point or a coordinate of an integer multiple of the reference point and a second auxiliary variable storing a second interim result representing another integer multiple of the reference point or a coordinate of another integer multiple of the reference point. The processor swaps a value stored by the first auxiliary variable and a value stored by the second auxiliary variable during calculation of the result of the scalar multiplication, if a swap condition depending on the generated random bit is fulfilled.

Abstract: A certain subset of temporal properties defined using local variables can be formally verified with complexity of PSPACE or less. A subset with this characteristic, referred to as a practical subset, is therefore feasible to formally verify. For example, it can be shown that temporal properties that possess an alternating automaton with no conflicts fall within a practical subset. Temporal properties are analyzed to determine whether they are a member of the practical subset. Members of the practical subset can then be feasibly formally verified.
