Antoine Pitrou commented on ARROW-13870:
----------------------------------------
Why would multithreading not work on 32-bit?
> [R] Should we proactively disable multithreading on 32bit windows?

> Key: ARROW-13870
> URL: https://issues.apache.org/jira/browse/ARROW-13870
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Jonathan Keane
> Priority: Minor
>
> We have numerous test skips for 32bit windows + multithreading. Should we add
> something to {{onLoad}} that detects this and proactively sets arrow to
> single-threaded (using {{set_cpu_count()}} and / or
> {{options(arrow.use_threads)}}?).
> Should we display a message that we did this and if someone wants to live
> experimentally they can increase that again?
