The paper considers an approach to reduce an amount of multiprocessing computing system's idle resources. The presented approach uses features of job scheduling mechanisms in modern batch systems, in particular, features of backfill algorithm. Authors developed the quasi scheduler, program that utilizes supercomputer idle resources under parallel job management system control (SUPPZ). Flowchart of the developed quasi scheduler is presented. Quasi scheduler's users can submit tasks without waiting in queue, if there are enough idle resources for task execution. Computational experiment's results presented in paper show effectiveness of supercomputer's scheduling depends of the quasi scheduler usage.
Keywords: effectiveness of scheduling, resource utilization, extra scheduler, backfilling algorithm.
