摘要:
A system includes an initiator and processing nodes. The initiator distributes portions of a transaction among the processing nodes. Each processing node has at least one downstream neighbor to which the processing node sends commit messages. The commit messages include a commit status of the processing node. The downstream neighbor is also a processing node.

In one example, a method for implementing recovery segments includes sending an application message from a parent process executed by a first computing device to a child process executed by a second computing device and identifying a dependency created by the application message. This identified dependency is included in a dependence set of the child process and saved. A checkpoint is generated by the parent process and a checkpoint message that includes dependency information is sent from the parent process to the child process. The child process modifies the dependence set according to the dependency information and generates a second checkpoint that is saved in nonvolatile memory of the second computing device. Upon occurrence of a failure of the parent process, the child process reverts to a most recent checkpoint generated by the child process that does not include the effects of processing an orphan message.

A shiftable memory is employed in a system and a method to shift a contiguous subset of stored data within the shiftable memory. The shiftable memory includes a memory having built-in shifting capability to shift a contiguous subset of data stored by the memory from a first location to a second location within the memory. The contiguous subset has a size that is smaller than a total size of the memory. The system further includes a processor to provide an address and the length of the contiguous subset. The method includes selecting the contiguous subset of data and shifting the selected contiguous subset.

An embodiment of a method of scheduling computer processing begins with a first step of receiving job properties for a plurality of jobs to be processed in a multi-processor computing environment. At least some of the jobs each comprise a plurality of stages, one or more tasks for each stage, and precedence constraints among the stages. The method continues with a second step of determining a schedule for processing at least a subset of the plurality of jobs on processors within the multi-processor computing environment from a solution of a mathematical program that provides a near maximal completion reward. The schedule comprises a sequence of tasks for each processor. In a third step, the computer processing jobs are processed on the processors according to the sequence of tasks for each processor.

A shiftable memory supporting in-memory data structures employs built-in data shifting capability. The shiftable memory includes a memory having built-in shifting capability to shift a contiguous subset of data from a first location to a second location within the memory. The shiftable memory further includes a data structure defined on the memory to contain data comprising the contiguous subset. The built-in shifting capability of the memory to facilitate one or more of movement of the data, insertion of the data and deletion of the data within the data structure.

An embodiment of a method of allocating computing resources begins with a first step of identifying applications which comprise candidates for execution on a shared computing system. In a second step, the method identifies at least one subset of the computing resources for each application. Each subset for a particular application comprises sufficient resources to support the particular application. The method continues with a third step of assigning a value to each subset. The method concludes with a fourth step of determining an assignment of the computing resources to the applications which provides a near maximal overall value.

摘要:
A process for preparing an aromatic carboxylic acid having a heteroatom containing substituent is provided that includes reaction in a vessel of an aromatic precursor having an aromatic core with at least one heteroatom containing substituent and at least one hydrogen extending from the core, with a haloacetonitrile under reaction conditions to form an aromatic acetonitrile with an acetonitrile moiety. The aromatic acetonitrile is exposed to an oxidizing agent under conditions to convert the acetonitrile moiety to a carboxylic acid group to prepare the aromatic carboxylic acid having the heteroatom containing substituent.
