Abstract
An example system includes a memory, at least one processor in communication with the memory, a plurality of threads executing on the at least one processor, and a supervisor. The supervisor is configured to preempt a first thread of the plurality of threads and determine a status of the first thread as either (i) executing in an atomic section or (ii) executing outside of the atomic section. The atomic section is a region of code tagged as atomic, and the atomic section includes instructions that run under a lock. Responsive to determining the status as executing in the atomic section, the supervisor is configured to notify a second thread of the plurality of threads to execute a system call based lock to block execution until the lock is released by the first thread.
