QUESTION
I wanna implement a high performance counter in multi-thread process, like this, each thread has a thread local counter named "t_counter" to count query(incr 1/query) and in "timer thread" there is a counter named "global_counter", what I want is each second, global_counter will get each t_counter(s) and add them to global_counter, but I dont know how to get each t_counter value in "timer thread". additional, which section will thread local value lay in main memory ? .data or heap or other? how to dynamic allocate memory size(there maybe 10 thread or 100 thread) ? and does x86-64 use segment register store such value?
...ANSWER
Answered 2022-Jan-06 at 07:46Starting with your second question, you can find all the specifications here.
Summarizing, thread local variables are defined in .tdata / .tbss. Those are somewhat similar to .data, however accessing those is different. These sections are replicated per thread. The actual variable offset is computed at the runtime.
A variable is identified by an offset in .tdata. Speaking of x86_64 it will use the FS segment register to find the TCB (Thread control block), using the data structures stored there it will locate the thread local storage where the variable is located. Note that all allocations are done lazily if possible.
Now, regarding your first question - I am not aware of a way to just list all the thread local variables from another thread, and I doubt it is available.
However, a thread can take a pointer to thread variable, and pass it to another thread. So what you probably need is some registration mechanism.
Each new thread will register itself to some main store, then unregister on termination. Registration and deregistration are on your responsibility.
Schematically, it would look like this:
QUESTION
I've been working on python to make a program which need to handle complex problem from list of dict. The thing is I need to transform this data into dictionary and sort it. The input for this function is come from trees. The code I share here is working, but takes a long time to run. In here I wanna ask is there any idea to make this function run more faster in python? I use python 3.7.3 if you ask. The reason I wanna improve this code is because when I tried to make input data for this function need around 3-4 hours, but to run this function need time around 21-22 hours (this really shock me).
here is the structure of data that I input on below:
...ANSWER
Answered 2022-Feb-08 at 00:52Without having the full code to test outputs this is harder to do, but it seems that there are some redundant processes that you are adding elements to a list of lists only to flatten that list and add that to a dictionary as a set. You can increase some of the speed and memory by removing that and instead just adding it to the dictionary right away.
There are some other tweaks that can be done such as using f-strings instead of string concatenation, using list comprehension, and removing having to do the same math in the loop (time_range * gamma) and instead just reference it by memory.
But these are all minor tweaks compared to your step one process which looks to be the largest time sink (approx N^4 in time complexity). I am unsure if it is larger as I don't see the functions that you use inside that for loop, but tweaking that to reduce the number of calculations would provide the largest benefit to time savings.

I am working on Glue in AWS and trying to test and debug in local dev. I follow the instruction here https://aws.amazon.com/blogs/big-data/developing-aws-glue-etl-jobs-locally-using-a-container/ to develop Glue job locally. On that post, they use Glue 1.0 image for testing and it works as it should be. However when I load and try to dev by Glue 3.0 version; I follow the guidance steps but, I can't open Jupyter notebook on :8888 like the post said even every step seems correct.
here my cmd to start a Jupyter notebook on Glue 3.0 container

Answered 2022-Jan-16 at 11:25It seems that GLUE 3.0 image has some issues with SSL. A workaround for working locally is to disable SSL (you also have to change the script paths as documentation is not updated).

QUESTION
i have created a function enc()
...ANSWER
Answered 2021-Nov-07 at 12:03You need to rework your function.
Python isn’t smart enough to know which part of the code you need multiprocessed.
Most likely it’s the for loop right, you want to encrypt the files in parallel. So you can try something like this.
Define the function which needs to be run for each loop, then, create the for loop outside. Then use multiprocessing like this.

You can only have dependent names inside of a template, if they depend on the template parameters of the enclosing templates.
