Abstract: A method for providing computer job forecasts includes storing a plurality of job queue files in random access memory. The plurality of job queue files includes information associated with a plurality of jobs. The method also includes accessing at least one of the job queue files stored in the random access memory and, in response, storing in random access memory forecast data defining a plurality of scheduled jobs that are scheduled to be executed, a plurality of datasets associated with the scheduled jobs, and connections between the jobs and datasets. The method also includes generating, based at least in part on the stored forecast data, a forecast for at least one particular job. The forecast provides an identification of a plurality of datasets and jobs directly and indirectly triggered by the particular job and a plurality of datasets and jobs required by the jobs and datasets triggered directly or indirectly by the particular job. The method also includes graphically displaying the forecast to a user.

Abstract: A predistortion circuit reduces composite second order intermodulation distortion products inherently generated by a laser diode. A radio frequency signal is split into a primary and secondary signal, and the secondary signal is amplified by an amplifier biased at a starvation current level so as to produce intermodulation distortion products having an amplitude relatively large compared to an amplitude of a fundamental generated by the amplifier. The amplitude and phase of composite second order intermodulation distortion products generated by the amplifier are adjusted so as to substantially match those inherently generated by the laser diode by the primary electrical signal, with the products being about 180.degree. out of phase relative to those generated by the laser in response to the primary signal.
