This MATLAB function executes a series of MATLAB statements for values of loopvar between initval and endval, inclusive, which specify a vector of increasing integer values.
for i=1:1024 A(i) = sin(i*2*pi/1024); end plot(A) To interactively run code that contains a parallel loop, you first open a MATLAB pool. This reserves a collection of MATLAB worker sessions to run your loop iterations. The MATLAB pool can consist of MATLAB sessions running on your...
Is it possible speed up the usual "for" loop in matlab code using "parfor" feature in "parallel processing toolkit" and a GPU system("Nvidia Tesla GPU C2050")? That is, can you create and deploy multiple matlab workers in GPU system just like in a machine with multiple CPU's?
for-loop iterations in parallel on workers in a parallel pool. MATLAB® executes the loop body commands in statements for values of loopVar between initVal and endVal. loopVar specifies a vector of integer values increasing by 1. If you have Parallel Computing Toolbox™, the iterations of...
This example calculates the spectral radius of a matrix and converts afor-loop into aparfor-loop. Find out how to measure the resulting speedup. In the MATLAB®Editor, enter the followingfor-loop. Addticandtocto measure the time elapsed. ...
In this case you do not even need a loop: x = (0:n - 1) * h; y = x; Replace: forj = 1:n fori = 2:n p0(i,j)=1; end end by p0 = ones(n, n); This is faster and nicer. Pre-allocate t also: tau = 0.01; ...
Run MATLAB Functions with Automatic Parallel Support (Parallel Computing Toolbox) Take advantage of parallel computing resources without requiring any extra coding. Interactively Run Loops in Parallel Using parfor (Parallel Computing Toolbox) Convert a for-loop into a scalable parfor-loop. Plot Durin...
forii = 1:100 Vqs{ii} = interp1(x,Data(ii,:),Xq+x(ii),'linear',0); end Note also that storing the interpolated data in a cell array is also optional. The goal is parallel gpu loop over interp1 operations from 1-D to 2-D grid where the grid varies. ...
(Need data edited in parfor-loop and returned)parfor can only reduce the memory transfer if the parfor index variable is used by itself, or itself plus a constant, as an entire dimension. No 2d strips of the array, no k:k+7 where k is the loop variable. Basi...
