However, if you have compiled a program on a system which uses Intel processors and you have used one or more options like -xXXXX, such as -xCORE-AVX2, the compiled program will not work on Narval because the Intel compilers add additional instructions in order to verify that processor used is an Intel product. On Narval, the options -xHOST and -march=native are equivalent to -march=pentium (the old 1993 Pentium) and should not be used.
