In CPython, multi-threading is supported by introducing aMutexknown as Global Interpreter Lock (aka GIL). It is to prevent multiple threads from accessing the same Python object simultaneously. This make sense, you wouldn’t want someone else to mutate your object while you are processing it....
As described in Figure 4-13, the original system did not have a process for every truly concurrent activity—the processing of a packet from end to end—but instead used a process for every different task—decoding, encoding, and so forth. Each open socket in Erlang was associated with a ...
list of the sequence, wherein the conflict between the first I/O list and the second I/O list is a first common block written to by both the first and second I/O lists; and performing first processing that modifies the first I/O list and the second I/O list to remove the conflict...
model0 and model1. Assuming Triton is not currently processing any request, when two requests arrive simultaneously, one for each model, Triton immediately schedules both of them onto the GPU and the GPU’s hardware scheduler begins working on both computations in parallel. Models executing on t...
Simple round-robin processing It is possible to implement a more sophisticated, and more useful, form of concurrency by adding a real-time operating system (RTOS) to the processor. This is a separate piece of software code that sits hidden in the background, and is normally not ‘seen’ ...
