I want to use Julia with MKL. As has been discussed, one currently has two options: use Julia Pro or build Julia from sources and setting flags. For many reasons I want to take the second approach.
Regarding performance, what compiler should I use to build Julia, icc or gcc? Does the choice influence performance at all. Here it has been mentioned that “Code generation is doen by LLVM so runtime performance AFAIU, run time performance should not depend on what you use to compile LLVM / Julia with.”
Is that true? Any ideas?
Using gcc is often more convenient and as far as I know automatically tested by the Julia team.
