Hi, Different processors have different SIMD capabilities, especially different vector sizes on which the processor can work at once. However, there are a few points w.r.t. code compilation which I am not sure about. If I understood correctly, Julia generates automatically SIMD code optimal to th…

[image] lungben: Pre-compiled binaries for shipping, however, would either need to be compiled for the lowest common denominator (i.e. not using SIMD capabilities of most modern CPUs to full extend) or require explicit treatment of different SIMD capabilities at runtime, correct? AFAIU Julia …

I had a related question a few years back. There I asked whether it matters which compiler (icc vs gcc) one uses when building Julia. The answer was pretty much no.
