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
