我在这里有一个小的无意义的脚本,我在MATLAB R2013b中执行:

clear all;

n = 2000;
times = 50;
i = 0;

tCPU = tic;

disp 'CPU::'
A = rand(n, n);
B = rand(n, n);
disp '::Go'
for i = 0:times
    CPU = A * B;
end

tCPU = toc(tCPU);
tGPU = tic;

disp 'GPU::'
A = gpuArray(A);
B = gpuArray(B);
disp '::Go'
for i = 0:times
    GPU =  A * B ; 
end
tGPU = toc(tGPU);

fprintf('On CPU: %.2f sec\nOn GPU: %.2f sec\n', tCPU, tGPU);

不幸的是,在执行后我收到来自Windows的消息说:" 显示驱动程序停止工作并已恢复. ". …
