Abstract: Techniques are provided for handling a trap encountered in a thread that is part of a thread array that is being executed in a plurality of execution units. In these techniques, a data structure with an identifier associated with the thread is updated to indicate that the trap occurred during the execution of the thread array. Also in these techniques, the execution units execute a trap handling routine that includes a context switch. The execution units perform this context switch for at least one of the execution units as part of the trap handling routine while allowing the remaining execution units to exit the trap handling routine before the context switch. One advantage of the disclosed techniques is that the trap handling routine operates efficiently in parallel processors.

Abstract translation: 提供了用于处理在作为在多个执行单元中执行的线程数组的一部分的线程中遇到的陷阱的技术。 在这些技术中，具有与线程相关联的标识符的数据结构被更新，以指示在执行线程数组期间发生陷阱。 同样在这些技术中，执行单元执行包括上下文切换的陷阱处理例程。 执行单元为至少一个执行单元执行该上下文切换，作为陷阱处理例程的一部分，同时允许剩余执行单元在上下文切换之前退出陷阱处理例程。 所公开技术的一个优点是陷阱处理例程在并行处理器中有效地操作。
