I doubt there would be a hard requirement on any AVX instructions, just that it can take advantage of them if available.

  A hard requirement on AVX instructions is exactly the sort of thing I would expect out of Arthur Whitney. His software tends to be very opinionated, and that's one of the things that lets him do so much in so little code.

  The version I downloaded from the site does (did?) depend on AVX instructions and would die on startup. There are other ('nightly builds') that fix this. One of the goals of the current team seems to be portability.

    FWIIW J is moving in this direction as well; the last release version of it (807) needed a special build for older intel hardware (they subsequently made separate binaries for older hardware). AVX has been around since 2011/2012, so it doesn't seem like that big a deal. Admittedly I myself have older hardware kicking around I see no real reason to upgrade, but AVX is such a big win on array processing you might as well make it a dependency for the kinds of use cases Shakti or J get used for in business.

  At present, there is a hard requirement, but from what I've heard, it is to be lifted in future

The first thing I would suggest is 'ldd binary' where binary is the name of the file--and make sure all shared libraries are found.

Last I was told - removing the avx hard requirement is on the roadmap. This Intel SDE emulator took care of issues I ran into on an older laptop running shakti release circa ~ September: https://software.intel.com/en-us/articles/intel-software-development-emulator https://software.intel.com/en-us/articles/intel-software-dev...
