  • Method and system for dedicating processors for desired tasks
    Patent number: 9720739
    Abstract: Improving the performance of multitasking processors are provided. For example, a subset of M processors within a system with N processors is dedicated for a desired task. The M (where M>0) of the N processors are dedicate to a task, thus, leaving N?M (N minus M) processors for running normal operating system (OS). The processors dedicated to the task may have their interrupt mechanism disabled to avoid interrupt handler switching overhead. Therefore, these processors run in an independent context and can communicate with the normal OS and cooperation with the normal OS to achieve higher performance.
    Type: Grant

  • Method and system for polling network controllers to a dedicated tasks including disabling of interrupts to prevent context switching
    Patent number: 8949833
    Abstract: Improving the performance of multitasking processors are provided. For example, a subset of M processors within a Symmetric Multi-Processing System (SMP) with N processors is dedicated for a specific task. The M (M>0) of the N processors are dedicate to a task, thus, leaving (N-M) processors for running normal operating system (OS). The processors dedicated to the task may have their interrupt mechanism disabled to avoid interrupt handler switching overhead. Therefore, these processors run in an independent context and can communicate with the normal OS and cooperation with the normal OS to achieve higher network performance.
