Hello,

thanks you very much for your attention.

In fact i have uninstall Visual Studio 2010 and Fortran Intel XE Composer and re install together. The problem has stop !

The screenshot was (from memory) :

"unknown option : -localonly (this first line i am sur)
hit a touch to quit the program (the second had this sens).

Now i have other "problem" about memory gestion in matrix multiplication : for some dimension of allocatable array the computing is good (product of two matrix 1023 x 1023 take less 2 or 3 seconds) and for other very bad (1024 x 1024 take near 10 s !!!).

I make detail report of this problem and i will communicate it if you are interested by this.

Bests regards

Hi Latomicien,

What is the size your processor's cash memory? what is the data type of the matrix elements?
This might be a granualrity issue, if so, partioning would help.
