problem of compile matrixMul error of compilation

[smeil]

hello, every body

i try to create my own code of multiplication of square matrix ,but when i would compile it

the message appear :

matrixMul.cu(96): error: a host function call can not be configured

1 error detected in the compilation of “/tmp/tmpxft_0000211c_00000000-4_matrixMul.cpp1.ii”.

you can view the link attached to my post

so if somebody can help me

[tera]

sorry this is my code

You are scribbling past the end of the host arrays. Change the initialization to

[font=“Courier New”]// initialize host memory

for (int i=0; i<Width*Width; i++) Ma[i] = (float)i;

for (int j=0; j<Width*Width; j++) Na[j] = (float)j;
