  • Transparent user mode scheduling on traditional threading systems
    Patent number: 9229789
    Abstract: Embodiments for performing cooperative user mode scheduling between user mode schedulable (UMS) threads and primary threads are disclosed. In accordance with one embodiment, an asynchronous procedure call (APC) is received on a kernel portion of a user mode schedulable (UMS) thread. The status of the UMS thread as it is being processed in a multi-processor environment is determined. Based on the determined status, the APC is processed on the UMS thread.
    Type: Grant

  • Intelligent context migration for user mode scheduling
    Patent number: 8321874
    Abstract: Performing directed switches between user mode schedulable (UMS) threads and primary threads enable proper execution of the UMS threads. A primary thread user portion is switched to a UMS thread user portion so that the UMS thread user portion is executed in user mode via the primary thread user portion. The primary thread is then transferred into kernel mode via an implicit switch. A kernel portion of the UMS thread is then executed in kernel mode using the context information of a primary thread kernel portion.
