Yes, however typical users do appear to expect or claim that, normally for the Intel compiler, on the basis of myth and not measurement and understanding. I'm not convinced there is typical numerical code across scientific applications, though; consider the (behaviour) on the Polyhedron Fortran benchmarks, for a start.
- xscott 6y agoI used to work with some folks who believed the Intel compiler was amazing. I think the logic to the myth was, "Who would better know how to optimize for Intel chips?". However, in my experience icc crashed more than any other compiler I've ever used (internal compiler errors). That kind of a bug in a compiler makes me really wonder what else is wrong under the hood. And of course, being closed source, I can't possibly know...
- gnufx 6y agoIndeed, and you can be told you have to use it even when it won't compile the code, or the result won't run correctly (and obviously you should use it and MKL on AMD hardware too). At least it's not as bad as the infamous "Pentium GCC" from long ago.
