Latest Patents
Chiranjib Sur's latest patents include innovative methods for job scheduling that balance energy consumption with performance. One of his notable patents is a method for job scheduling that aims to reduce energy consumption while maintaining schedule performance. This energy-aware backfill scheduling method combines overestimation of job run-times with processor adjustments, such as dynamic voltage and frequency scaling. By identifying job performance data for various representative jobs, Sur's method runs simulations to optimize the combination of run-time over-estimation values and processor adjustment values. This results in a scheduling approach that minimizes energy consumption while ensuring timely job execution.
Another significant patent focuses on energy and performance optimizing job scheduling. This method involves queuing jobs and characterizing them as either hot or cold. By specifying sub-queues for hot and cold jobs, Sur iteratively determines schedules based on user-provided parameters and energy-performance heuristics. The process includes estimating performance and power characteristics to ensure that the selected schedule meets predefined criteria. If the criteria are not met, adjustments are made for subsequent iterations until an optimal schedule is achieved.
