Abstract
Examples of techniques for a thread checkpoint table for a computer processor are described herein. An aspect includes, based on detecting an early power-off warning (EPOW) signal, determine, based on a thread checkpoint table, whether a status of a thread of a processor indicates that the thread has begun a unit of atomic work. Another aspect includes, based on determining that the status of the thread of the processor indicates that the thread has begun the unit of atomic work, allowing the thread to continue execution of the unit of atomic work. Another aspect includes determining, based the status of the thread in the thread checkpoint table, that the thread has completed the unit of atomic work. Another aspect includes, based on determining that the thread has completed the unit of atomic work, suspending the thread.
