parallel_for (int(0), int, [&](int i) { for(int j=0;j<n;j++) { mat_ans[i][j]=0; for (int k=0;k<n;k++){ mat_ans[i][j]+=(mat_1[i][k]*mat_2[k][j]); }}} replace the code with the above code.The outer loop will be divided into smaller tread using the paraller_for.

write an OpenMP program to to optimize matrix multiplication (matmul) code to run fast on a single processor core We consider a special case of matmul: C := C + A*B where A, B, and C are n x n matrices. This can be performed using 2n3 floating point operations (n3 adds, n3 multiplies), as in the following pseudocode: for i = 1 to n for j = 1 to n for k = 1 to n C(i,j) = C(i,j)...

Using java, I am trying to recreate an arithmetic logic unit which performs an integer multiplication. I should able to get an output like this: 387637653 x 366499587 = 142069039730149311 But I am not sure because something is wrong apparently. The algorithm of the program goes like: Test multiplier0 If multiplier0 = 0 Shift the multiplicand register left 1 bit Shift the multiplier register right 1 bit If multiplier0 = 1 Add multiplicand to product and place the result in...

i created a two dimensional matrix class which holds my object complex number. I am trying to overload the parenthesis () so that I can access and modify the value at specified location of the matrix. say matrix[a][b] = 5; and my_vals is a private member of the matrix class. What is the problem with my code //constructor & inlitilize dynamic array matrix::matrix(int rows, int cols) { complex** m_vals = new complex * [rows]; for (int i = 0; i...
