    摘要: Method and system aspects for mapping tasks to iteratively improve task assignment in a heterogeneous computing (HC) system include identifying a current machine that defines a makespan in the HC system. Further included is the reassigning of at least one task from the current machine to at least one alternate machine in the HC system according to a predefined reassignment constraint. Reassigning also includes reassigning the at least one task when the at least one alternate machine can perform the at least one task in addition to previously assigned work while finishing in less time than the time of the makespan reduced by time required for the task being reassigned.

    摘要: Provided are a method, system, and article of manufacture for converting image data in an input color space to an output color space in a transform domain. An input block of coefficients in an input color space is generated, wherein the input block includes a first type coefficient and a plurality of second type coefficients. The first type coefficient in the input block is converted to an output value in an output color space. The output value is used to determine a scaling factor for the second type coefficients. The scaling factor is applied to the second type coefficients to determine second type coefficients in the output color space. A component output block of coefficients in the output color space is formed from the output value for the first type coefficient and the determined second type coefficients in the output color space.

    摘要: The scaling down of data is provided. At least two blocks of transformed data samples representing at least two blocks of original data samples are received. One of at least two tables of constants is selected wherein each table of constants is capable of reducing the number of transformed data samples by a different factor. The constants taken from the selected table are applied to the at least two blocks of transformed data samples to produce one block of transformed data samples representing one block of final data samples. The data is processed one dimension at a time by multiplying the data in one dimension with selected constants taken from previously developed tables corresponding to the desired scale down factor. Scaling down by different factors in each dimension as well as scaling down in one dimension and scaling up in the other dimension may be achieved. In addition, the de-quantization of the quantized transform coefficients may be accomplished by pre-multiplication of the selected constants when the quantization values are known. In a similar way the re-quantization may be accomplished by a pre-division of the selected constants. Both de-quantization and re-quantization may be combined when the input quantized transform coefficients and output quantized transform coefficients are desired.

    摘要: Provided are a method, system, and article of manufacture for mapping an input color value in an input color space to an output color value in an output color space. A lookup table in a computer readable medium maps an input value having color components in an input color space to an output color value in an output color space. The lookup table has n number of possible values for a fixed color component in the input color space and less than n number of possible values for t color components in the input color space. An input value in the input color space is received and a determination is made of surrounding input values in the lookup table surrounding the input value in a t dimensional space, wherein each surrounding input value has a same value for the fixed color component. A determination is made from the lookup table of surrounding output values in the output color space to which the determined surrounding input values map. The determined input and output surrounding values and the input value are used to estimate an output value in the output color space for the received input value in the input color space.
