I have a function that should always return A[0][1]. But I use std::async and gcc says: test_fibonacci_method/1/main.cpp:147:1: warning: control reaches end of non-void function [-Wreturn-type] Integer Fib_iterative_n_Matrix(const unsigned& n) { if (n < 2) return n; // Fib(0):=0 and Fib(1):=1 std::array<std::array<Integer,2>,2> A = {1,0,0,1}, FIB = {1,1,1,0}; auto a = std::async(std::launch::async, [&]() { Matrixpower_A_time_B_pow_x(A, FIB, ..

Overview : I have a client-server implementation, which uses DBus(sdbus-c++) to send asynchronous requests to a server. Now my server interacts with hardware APIs which behaves synchronously and also takes significant time to generate a reply. So I have a std::queue at server, that holds all the asynchronous requests received, and processes them one by ..

I am trying to understand how exactly async differs from using threads. On a conceptual level, I thought multithreading was by definition asynchronous, because you are doing context switches between threads for things like I/O. But it seems that even for instances like single-threaded applications, just adding threads would be the same as using async. ..

i have successfully multithreaded my code but the result is very slow , i there are no thread conflict and yet i am getting very slow code. the program is to use gaussian elimination to solve system of equations , and i have used async to parallelize the matrix row operations. asynchronous: void ge(Mat &mat) ..

i have written simple class to solve system of linear equations , to parallelize the matrix row subtractions i used std::async . after size of 10×10 matrix the program is crashing due to segmentation fault. my first implementation was to replace vecSub((mat[c]), (temp)); with just std::async(std::launch::async, vecSub, std::ref(mat[c]), std::ref(temp)) but then discovered that if we ..
