Abstract: A method, system, and computer usable program product for equation based retargeting of design layouts are provided in the illustrative embodiments. A set of desirable combination of values of a set of layout parameters of the design layout is determined. A desirable region that includes the set of the desirable combination of values is determined. An equation is computed to determine a retargeting value for a first combination of values of the set of layout parameters with respect to the desirable region. Instructions are generated to adjust a value in the first combination to generate a second combination of values of the set of layout parameters such that the second combination falls in the desirable region. A shape in the design layout is retargeted such that the retargeted shape uses the second combination of values of the set of layout parameters. The IC is manufactured using the retargeted shape.

Abstract: A method, system, and computer usable program product for using a dual mode reader writer lock. A contention condition is detected in the use of a lock in a data processing system, the lock being used for managing read and write access to a resource in the data processing system. A determination of the data structure used for implementing the lock is made. If the data structure is a data structure of a reader writer lock (RWL), the data structure is transitioned to a second data structure suitable for implementing the DML. A determination is made whether the DML has been expanded. If the DML is not expanded, the DML is expanded such that the data structure includes an original lock and a set of expanded locks. The original lock and each expanded lock in the set of expanded locks forms an element of the DML.

Abstract: A system, and computer usable program product for recovery in a shared memory environment are provided in the illustrative embodiments. A core in a multi-core processor is designated as a user level core (ULC), which executes an instruction to modify a memory while executing an application. A second core is designated as a operating system core (OSC), which manages checkpointing of several segments of the shared memory. A set of flags is accessible to a memory controller to manage a shared memory. A flag in the set of flags corresponds to one segment in the segments of the shared memory. A message or instruction for modification of a segment is received. A cache line tracking determination is made whether a cache line used for the modification has already been used for a similar modification. If not, a part of the segment is checkpointed. The modification proceeds after checkpointing.

Abstract: A method and a corresponding apparatus for inventorying software products on a plurality of computer are proposed. The inventorying system aims at populating a software catalogue without the manual intervention of an administrator. The present invention reduces the cost of producing and maintaining a comprehensive knowledge base (the catalogue) which contains definitions of software products and the related signature. Information about software products and their related signature is obtained through a process which gathers information from a potentially very large collection of computers. Any occurrence of a group of identical files across multiple computers is considered a reliable indicator that they belong to the installation footprint of a product.

Abstract: A method and a corresponding apparatus for forwarding incoming calls according to the current position of the intended receiver. The position is detected by means of RFID tag and corresponding detectors. A plurality of telephone receivers are distributed within the offices of one or more sites of an entity (e.g. a private Company or Corporation or a Public Body) all connected together by means of a switchboard system. A corresponding plurality of detectors are positioned in proximity of the telephone receivers, so that the presence of an RFID tag is detected whenever it comes within a predetermined distance. Such presence of the RFID tag (and consequently the presence of the person carrying the tag to whom a telephone number is assigned) next to a target telephone receiver will then be communicated to a Central Switchboard.

Abstract: Systems, methods, and computer program products for alerting system administrators and owners about suspect communications, such as communications from open relay, blacklisted, and blocked computers, are disclosed. Embodiments comprise receiving information related to a communication of an electronic document from one computer to another, determining if the sending computer is either blacklisted, and alerting the administrator or owner of the sending computer if it is identified as suspect. In some embodiments, determining if the sending computer is suspect comprises examining blacklisted IP addresses and/or blacklisted domain names. Some embodiments determine the identity of the administrator by examining WHOIS database information. In some embodiments, alerting the administrator or owner comprises sending them an e-mail.

Abstract: A method, system, and product for monitoring the availability of a data processing system are proposed. The system runs a management application involving the periodic transmission of blocks of data from multiple local computers to a central computer. Whenever a block of data must be transmitted by a generic local computer, an expected transmission delay of a next block of data (with respect to the current one) is estimated and attached to the block of data. The central computer receiving the updated block of data can calculate an expected receiving time of the next block of data accordingly. If the next block of data is not received in due time, the central computer determines a failure of the local computer. The central computer also scans a subset of ports of the local computer, to ascertain whether the problem is due to a temporary unavailability of the application.

Abstract: A method, system, and computer usable program product for preserving references to deleted directory entries are provided in the illustrative embodiments. An instruction to delete an entry is received. A second entry referencing the entry is identified. The second entry is marked as a ghost reference to the entry. The entry is converted to a deleted entry. A ghost attribute with a value of “false” may be added to the entry. A ghost attribute or tag with a value of “false” may be added to the second entry. The ghost tag may correspond to an attribute of the second entry that references the entry. An entry may be deleted by setting a value of a ghost attribute in the entry to true. The second entry may be marked as the ghost reference by setting a value of a ghost attribute or a ghost tag in the second entry to true.

Abstract: A method, system, and computer usable program product for fracturing a continuous mask usable in photolithography are provided in the illustrative embodiments. A first origin point is selected from a set of points on an edge in the continuous mask. A first end point is identified on the edge such that a separation metric between the first origin point and the first end point is at least equal to a threshold value. Several alternatives are determined for fracturing using the first origin point and the first end point. A cost associated with each of the several alternatives is computed and one of the alternatives is selected as a preferred fracturing. Several pairs of origin points and end points are formed from the set of points. Each pair has a cost of a preferred fracturing between the pair. The continuous mask is fractured using a subset of the several pairs.

The analytic function instance is instantiated if both the object and the set of data sources are present in an object graph where the analytic function instance is to be instantiated.

Abstract: A self-adaptive resource management method (200) is proposed. The system is based on an authority (105) that publishes multiple rules into a corresponding repository (115). Each rule defines a desired target configuration for a category of subjects (110); each category is specified by one or more attributes that are evaluated by corresponding scanners (233-239). Whenever new rules are published, a dedicated module (120) creates and publishes further rules for selectively installing the scanners that are required for evaluating the attributes included in the categories of the new rules. These further rules are defined according to an algorithm that attempts to minimize the cost involved by the installation of the scanners.
