摘要： The subject disclosure pertains to implicitly and adaptively parallelizing program language-integrated operations comprising queries and the like. In particular, a parallel execution plan can be generated and/or selected based on static information surrounding operations. The plan can be augmented subsequently or concurrently based on dynamic information concerning the operations, machine topology, utilization, as well as data characteristics, among other things. As a result, sizeable parallel speedup can be obtained upon execution of the plan and evaluation of the operations.

摘要： The subject disclosure pertains to systems and methods for supporting null capabilities for general purpose programming languages. Low level, runtime support for a nullable type is provided to ensure consistency and coherency. An execution component restricts support of the nullable type to programming language types that lack a null capability. The execution component may also provide support for conversion between the nullable type and a reference type.

摘要： A method of performing a cancellation of concurrent worker objects includes creating a plurality of concurrent worker objects with a manager object. At least one cancellation object is generated with the manager object. The at least one cancellation object includes a cancel method and a register method that support concurrent calls. A callback function is registered by calling the register method with one of the concurrent worker objects. A cancellation of the concurrent worker objects is requested by calling the cancel method with the manager object.

摘要： A query that identifies an input data source is received. The input data source is partitioned into a plurality of partitions. Each of the partitions includes a set of data elements with an associated set of indices for indicating an ordering of the data elements. A query type for a query operator in the received query is identified. It is determined whether a reordering of data elements will be performed based on the identified query type. The data elements in at least one of the partitions are reordered when it is determined based on the identified query type that reordering will be performed.

摘要： A method of providing lock-based access to nodes in a concurrent linked list includes providing a plurality of striped lock objects. Each striped lock object is configured to lock at least one of the nodes in the concurrent linked list. An index is computed based on a value stored in a first node to be accessed in the concurrent linked list. A first one of the striped lock objects is identified based on the computed index. The first striped lock object is acquired, thereby locking and providing protected access to the first node.

摘要： The present invention relates to card payment systems. In particular, the present invention relates to systems and methods for processing payment card transactions in a dynamic currency conversion and/or multi-currency scheme. To operate correctly, ghost transactions are used. However to prevent duplication of debits against the Card Holder, these “ghost copy” transactions must not be processed into the card schemes with the normal transactions. Thus the Acquirer's and/or third parties host systems have to be amended, in addition to modifications to the related accounting thereof. To overcome this necessity, the present invention provides a method for effecting the performance of a payment card transaction for a first transaction amount in a first currency, between a first merchant and a first payment card holder, the method comprising the steps of a) creating a first payment card transaction record between the first merchant and a second cardholder for the first transaction amount, b) creating a second payment card transaction record between a second merchant and the first cardholder, wherein the second transaction record identifies a second transaction amount in a second currency which equates to the first transaction amount converted into the second currency, and submitting the first transaction record and the second transaction record for processing as payment card transactions.
摘要翻译：本发明涉及卡支付系统。特别地，本发明涉及以动态货币兑换和/或多币种方案处理支付卡交易的系统和方法。要正常运行，使用ghost事务。但是，为了防止对持卡人的借记重复，这些“鬼魂复制”交易不能通过正常交易处理到卡方案中。因此，除了对相关会计的修改外，还必须修改收购方和/或第三方主机系统。为了克服这种需要，本发明提供一种用于在第一商家和第一支付卡持有者之间执行第一货币的第一交易金额的支付卡交易的方法，所述方法包括以下步骤：a）创建在第一商户和第二持卡人之间的第一交易金额的第一支付卡交易记录，b）在第二商家和第一持卡人之间创建第二支付卡交易记录，其中第二交易记录标识第第二笔货币等于首次交易金额转换成第二种货币，并提交第一笔交易记录和第二笔交易记录作为支付卡交易处理。

摘要： A method of parallel processing an ordered input data stream that includes a plurality of input data elements and a corresponding plurality of order keys for indicating an ordering of the input data elements, with each order key associated with one of the input data elements, includes processing the input data stream in a parallel manner with a plurality of worker units, thereby generating a plurality of sets of output data elements. The plurality of sets of output data elements is stored in a plurality of buffers, with each buffer associated with one of the worker units. An ordered output data stream is output while the input data stream is being processed by outputting selected output data elements from the buffers in an order that is based on the order keys.
