I am a new user for the fortran. When I compile my code, I got this error message:
======================================
/tmp/ifort1nztqP.o(.text+0x19): In function `fpres_':

========================================
Old code: I have an old version of the code, in which, it uses unrolling loop as follows:
do i=1,64,8
x(i)=y(i);x(i+1)=y(i+1);x(i+2)=y(i+2);x(i+3)=y(i+3);x(i+4)=y(i+4);x(i+5)=y(i+5);x(i+6)=y(i+6);
x(i+7)=y(i+7);
enddo
For this old code, for the size 256^3, it can be compiled without any errors.
New code: But, after I change it to the following newway(delete the unrolling loop), I got the above error message.
do i=1,64
x(i)=y(i)
enddo
My confusion is: After I delete the unrolling loop, but decrease the computing size from 256^3 to 128^3, the new code can be compiled without any error. But when I increase the size back to 256^3, above error messages showed up.
Could anyone please explain what does this error message mean? Could you please teach me how to find where the problem is in my code?
thanks a lot!!
