Network processes within a group of network processes are configured to share stack space by controlling when a context switch may be performed between processes in the group. Since a context switch will not be performed between group members during execution of the event loop, the dedicated stack requirements of the process are limited to that required to store state information when the process is idling on a select function. This reduces system stack requirements by allowing a large portion of the stack to be shared by multiple network processes without creating unintended dependencies between the processes. A semaphore may be used to control access to the shared stack space to prevent unintended context switches between group members. If there is more than one group of processes, the operating system may perform context switches between processes in different groups since each group has its own dedicated area of shared stack.

A method of integrating an Xt Intrinsics based toolkit with a JAVA application. The application includes a process thread that implements an X event loop and an application thread that suspends execution of the event loop to allow a call to be made through the JAVA Native Interface to a toolkit or a widget to cause something to be displayed. The application thread includes a write socket to communicate a token to a read socket of the event loop, and performs a blocking read suspending the thread. The event loop returns an acknowledgment token via a write socket to a read socket of the thread that unblocks its blocking read and the event loop invokes its own blocking read suspending its execution. The file descriptor function, XtAppAddInput, preferably, is used to read the token and to set the blocking read. After a toolkit call is made, a token is sent from a second write socket of the thread to a second read socket of the event loop that unblocks its blocking read resuming the event loop. JAVA multithreading support services, such as JAVA's wait and notifyAll methods, are employed in multithreaded applications to ensure that only one thread at a time can make a call. Use of a separate Intrinsics application context to service the event loop is employed, windows are managed in separate hierarchies associated with each application context, and a special JAVA Canvas manages native windows transparent to the programmer.

A system creates and monitors virtual threads within a node.js application. Callbacks executing within an event loop for a node.js system are identified and may be traced. The callbacks are associated with a context, and resources associated with execution flow during each context may be identified. Callback registrations, callback calls, and callback completion messages may each be detected and recorded. Each registration, call, and completion message is associated with a virtual thread or other transaction identifier. The timing information for each virtual thread and other resource usage for each context may then be identified, stitched together for distributed transactions and reported to a user to provide more detail for node.js application processing.

An event queue is maintained to store IO events generated from a number of sensors and timer events generated for a number of autonomous driving modules. For each of the events pending in the event queue, in response to determining that the event is an IO event, the data associated with the IO event is stored in a data structure associated with the sensor in a global store. In response to determining that the event is a timer event, a worker thread associated with the timer event is launched. The worker thread executes one of the autonomous driving modules triggered or initiated the timer event. Input data is retrieved from the global store and provided to the worker thread to allow the worker thread to process the input data.
