<div dir="ltr">(Hi, as someone from the Numba project, my apologies for wading into this discussion late.)<div><br></div><div>Last time we checked, Numba on ARM was pretty close to working already. We have an open PR for ARMv7 that we just ran out of time to finish QA'ing (<a href="https://github.com/numba/numba/pull/1968">https://github.com/numba/numba/pull/1968</a>) a while ago, and never have gotten back to because there was not much demand at the time. It sounds like this is tripping up more people now, so we can take a look again.</div><div><br></div><div>One thing that really is unpleasant on ARM is compiling LLVM, so we would probably want to make sure we had conda packages and wheels available for llvmlite on ARM. Is there any precedent for posting Linux ARMv7 wheels to PyPI? (For conda, we would just make sure they appear in Jonathan's berryconda channel.)</div><div><br></div><div>A more difficult platform is POWER8, where we tried to do a port and got stuck last year. Recently, someone has figured out what the issues were, and it sounds like several of them stemmed from LLVM bugs in the POWER8 backend that may or may not be fixed in the next release. IBM is interested in improving the situation, so hopefully that will be sorted out soon. </div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Mar 6, 2018 at 4:54 PM, Matthew Brett <span dir="ltr"><<a href="mailto:matthew.brett@gmail.com" target="_blank">matthew.brett@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On Tue, Mar 6, 2018 at 9:21 PM, CJ Carey <<a href="mailto:perimosocordiae@gmail.com">perimosocordiae@gmail.com</a>> wrote:<br>

Yes, that's a worry I have too. You may remember Samuel Maybury on<br>
the mailing list recently sighing somewhat when he found he had to get<br>
numba installed on the Raspberry Pi. My guess is numba will be fine<br>
on the standard platforms and a significant problem on non-standard<br>
ones.<br>
<br>
Cheers,<br>
