Dear Sir
I use PGI compiler with VS2010, windows 7 and Gforce GTX750ti.
I want to know GPU’s timing, so I use set PGI_ACC_TIME=1 in cmd window. Then I use pgf90 -acc -Minfo=all to compile my F77 program and run.
But I did not get the timing result,but the attached warning messages:
Warning: ieee_underflow is signaling
Warning: ieee_inexact is signaling
FORTRAN STOP
I don’t why I get such message,please kindly advise me.
