AMD vs Intel

Dear All,

I am testing the new Epyc processors from AMD (comparing with Intel
Xeon), and getting different results. Just wondering whether anybody
faced the problem of differences between AMD and Intel processors and
knows how to solve it. I am using Intel compiler but ready to switch to
gfortran or anything else if this would help to get identical results.
There were reports of Intel slowing the AMD execution in the past, but
in my tests, speed is comparable but the results differ.
