Wasn't it the case that previously you observed AVX disabled, because of GDS? With AVX disabled, AVX512 would be implicitly disabled, too. Then migrating from an AVX512-capable host to an AVX512-incapable one would of course work. Yet of course this is only an example, because I don't know whether AVX512 is what your new inquiry would have been about. As indicated - please provide sufficient detail so we actually know what you're doing and what you observe. Jan
