Embodiments of the present disclosure provide a method and a coroutine framework for processing parallel tasks, a device, a medium and an unmanned vehicle. The method includes: switching a current coroutine to a target coroutine in response to a task switching instruction, in which, the coroutine is created at a user layer for processing a task, and the coroutine at the user layer is executed by a thread at a kernel layer; and saving context of a task processed by the current coroutine, and reading context of a task processed by the target coroutine, such that the thread at the kernel layer corresponding to the target coroutine processes the task based on the context of the target coroutine when executing the target coroutine.

Method for processing parallel tasks in unmanned vehicle system, and unmanned vehicle system

The present application provides a message transmission method and apparatus, a device and a medium. The method includes: determining and outputting, by an issuing task, a data message, storing the data message in a preset storage space, and sending an issuing notification message; and reading, by a subscription task, the data message from the preset storage space according to the issuing notification message. With embodiments of the present disclosure, transmission efficiency of the data message between the issuing task and the subscription task may be improved, and source occupancy may be reduced.

Message transmission method and apparatus, device and medium

The embodiments of the present disclosure provide a method and a device for implementing read-write lock reentry, a terminal and a storage medium. The method includes: receiving a write lock request of a thread to a target resource; in response to determining that the target resource is in a write-lock-exclusive state, acquiring a historical write-lock thread to the target resource that is in the write-lock-exclusive state; in response to determining that the thread is identical to the historical write-lock thread, adding a new lock of the thread to the target resource.
