# Important notes on why to use level triggered mode in this scenario
|
||||
For monitoring multiple clients sending data frequently, you should generally use level-triggered mode with epoll() for simplicity and reliability.
|
||||
|
||||
Level-Triggered Mode: In this mode, the epoll_wait() function returns whenever there is data available to read or write on a socket, as long as the socket remains ready. You use recv() or send() to read or write the data. This mode is more suitable for handling frequent data transmission, as the socket remains in the ready state until all available data is processed.
|
||||
|
||||
Edge-Triggered Mode: In this mode, the epoll_wait() function returns only when the socket transitions from not ready to ready. You need to process data until EAGAIN is received, at which point you should exit the loop and re-register the socket with EPOLLONESHOT to be notified again when the socket becomes ready again. This mode requires more careful management, as you must handle the data until no more is available, and it can lead to more complex code.
|
||||
|
||||
Given your description of continuous data transmission causing the application to hang in edge-triggered mode, and considering your preference for handling frequent data transmission, level-triggered mode seems like the better choice. It allows you to focus on processing data without worrying about handling the edge conditions and re-registering the socket.
|
||||
|
||||
From a theoretical standpoint:
|
||||
|
||||
Edge Triggered: This mode provides more fine-grained control and can potentially be more efficient, especially in scenarios where data arrival might be infrequent and you want to be notified only when there's a change in socket readiness.
|
||||
|
||||
Level Triggered: This mode simplifies handling continuous data flow, as the socket remains in the ready state as long as data is available, which is often more suitable for high-frequency data streams.
|
||||
|
||||
Ultimately, your choice should depend on the nature of your application and how you want to manage the data flow. While edge-triggered mode can be used with careful handling, level-triggered mode is generally simpler and more straightforward for frequent data transmission scenarios.
|
||||
|
||||
|
||||
|
||||
Exactly, you've got it right! In scenarios where you need to read and buffer all available data for later processing, level-triggered mode is the better choice. It ensures that you'll be continuously notified as long as there's data available to read, allowing you to consume and buffer the data without worrying about missing any part of it.
|
||||
|
||||
Level-triggered mode is particularly well-suited for scenarios where you want to handle data consumption and processing at your own pace, as the socket remains in the ready state as long as data is available, ensuring that you have the opportunity to read all available data before continuing with other tasks.
|
||||
|
||||
So, for your specific use case of reading all the data available and buffering it for later use, level-triggered mode with epoll() is a solid choice.
|
||||
|
||||
Yes, your approach of using one thread for epoll-based socket monitoring and another thread for data analysis using thread-safe queues is a valid and common way to handle this kind of scenario. Here's a high-level overview of how your setup would work:
|
||||
|
||||
Epoll Thread: This thread will use epoll() with level-triggered mode to monitor multiple sockets for incoming data. Whenever data is available to read on a socket, the epoll thread can read the data and enqueue it into the thread-safe queue.
|
||||
|
||||
Data Analysis Thread: This thread will be responsible for dequeuing the buffered data from the thread-safe queue and performing the necessary analysis on it. Since the queue is thread-safe, you won't have to worry about synchronization issues between the two threads.
|
||||
|
||||
This separation of concerns allows you to isolate the low-level socket I/O and buffering logic from the data analysis logic, making your application more modular and maintainable.
|
||||
|
||||
Keep in mind a few considerations:
|
||||
|
||||
Concurrency: While using multiple threads can improve parallelism, it also introduces complexity. Ensure that you handle thread synchronization and communication properly to avoid race conditions or deadlocks.
|
||||
|
||||
Resource Management: Manage your data buffers carefully to avoid excessive memory consumption, especially if data arrives rapidly. Consider setting limits on the size of your buffers and implementing buffer recycling mechanisms if needed.
|
||||
|
||||
Thread Safety: Make sure the data analysis thread doesn't access or modify the same data buffers that the epoll thread is using. This is where your thread-safe queue comes in handy, as it provides a clean boundary between the two threads.
|
||||
|
||||
Error Handling: Implement robust error handling mechanisms to gracefully handle unexpected situations, such as socket errors or issues with the thread-safe queue.
|
||||
|
||||
Overall, your proposed approach seems reasonable and can be an effective way to achieve your goal of efficiently buffering data for later analysis while utilizing multi-threading for improved performance.

this test wants to see how much data is possible to gather in 60 seconds with select and epoll.
|
||||
For that reason, I'm removing the random time between provider data generation and send it asap.
|
||||
I'll spawn 50 clients and let them connect and send data as fast as they can while I measure total received data on server side.
|
||||
I'm ignoring all bottlenecks for now. All tests of this section are brought out on my local machine.
|
||||
|
||||
EDIT: by default all clients allocate a massive 100 megabytes of space to send big chunks of data.
|
||||
To test with a bigger number of descriptors (I'm making 100, 500, 1000) i'm lowering the chunk size as well as changing
|
||||
the generation method of the data to send.
|
||||
So trashing first result with 50 and re executing with all the different clien numbers.
|
||||
|
||||
|
||||
since no big performance difference (as expected, since with all clients active also epoll has to iterate through everything since it gets notified from all),
|
||||
retesting with timeout on majority of clients. files with *_TIMEOUT.csv have only 50 clients without timeout, files with *TIMEOUT_HARD.csv have only 2 clients.
|
||||
The timeout is pretty hard, we're talking 1 second, to hilight the difference in performance.
|
||||
With epoll we see a big rise in throughput with the 2 clients, since we kill cpu time for iteration and optimize the 30 seconds time analysis,
|
||||
in the 50 clients it's not so evident. With 50 we start to see already big improvements with epoll vs select.
|
||||
|
||||
Now I try to multithread epoll, to see if the data acquired increases. I'll measure the full bandwith received, I expect a semi-linear increase in performance.
|
||||
For the multithreading thread check the threads folder

# Is epoll really thread safe?
|
||||
|
||||
### Motivation
|
||||
Scope of this test is simply to verify that TCP communication with epoll doesen't mix data. In particular, it's important to verify that if one big chunk is sent, the TCP protocol doesen't split it into different events for level triggered epoll (ofc it's gonna be splitted due to buf size).
|
||||
|
||||
The important thing is that if I send 1MB of data, it doesen't wake up 2 threads listening to the same fd just because TCP split the package (afaik that shouln't happen, but it's always better to verify, since [`epoll()` is fundamentally broken](https://idea.popcount.org/2017-02-20-epoll-is-fundamentally-broken-12/)).
|
||||
|
||||
Tested on sending buffer of size 1000 (receiving size 8 2 threads) with simulation re-executed 1000 times -> no reordering. This approach should then be considered safe and used in the project.
|
||||
File diff suppressed because it is too large
