    摘要： A method and system of simulating a cost of shipment are provided. A request for quote (RFQ) is received by a computing device from a shipper having a plurality of trade lanes. A revenue generated from each trade lane is estimated and ranked based on the estimated revenue. An original time limit is assigned to each trade lane. A trade lane with a highest ranking that has not yet been selected is selected. For the selected trade lane, graphs for space and time granularity analysis are generated. Space and time granularities that maximize accuracy within the assigned time limit based on the generated graphs are calculated. Cost simulation analysis is performed using the calculated space and time granularities. Upon determining that there are trade lanes not yet selected, there is a return to the act of selecting a trade lane.

    摘要： Embodiments include methods, systems and computer program products for providing an extendable job structure for executing instructions on an accelerator. The method includes creating a number of data descriptor blocks, each memory location addresses and a pointer to a next of the number of the data descriptor block. The method further includes creating a last data descriptor block having memory location addresses and a last block indicator. Based on determining that additional memory is required for executing instructions on the accelerator, the method includes modifying the last data descriptor block to become a data extender block having a pointer to one of one or more new data descriptor blocks and creating a new last data descriptor block.

    摘要： In an exemplary embodiment of this disclosure, a computer-implemented method includes determining that a database query warrants a first projection operation to project a plurality of input rows to a plurality of projected rows, where each of the plurality of input rows has one or more variable-length columns. A first projection control block is constructed, by a computer processor, to describe the first projection operation. The first projection operation is offloaded to a hardware accelerator. The first projection control block is provided to the hardware accelerator, and the first projection control block enables the hardware accelerator to perform the first projection operation at streaming rate.
