Antoine Pitrou commented on ARROW-11217: ---------------------------------------- Note that I'm testing with git master, not 2.0.0. > [C++] Runtime SIMD check on Apple hardware missing > -------------------------------------------------- > > Key: ARROW-11217 > URL: https://issues.apache.org/jira/browse/ARROW-11217 > Project: Apache Arrow > Issue Type: Bug > Components: C++ > Reporter: Neal Richardson > Priority: Critical > Fix For: 3.0.0 > > > [~jeroenooms] hit a crash in the "sum" compute kernel using the R package on > a new M1 machine running the rosetta emulator: > https://gist.github.com/jeroen/c60548b29ff7f6807a6554799bd01cb7 > According to > https://developer.apple.com/documentation/apple_silicon/about_the_rosetta_translation_environment, > we should be checking sysctlbyname for AVX* capabilities, but we are not. We > only use that function in > https://github.com/apache/arrow/blob/master/cpp/src/arrow/util/cpu_info.cc#L350-L359 > to check cpu cache size. > This may also explain a crash we observed previously on a very old macOS CRAN > machine. > I think we should to resolve this before the 3.0 release if possible, in > order to avoid bug reports as more people get M1s. > cc [~apitrou] [~uwe] [~kou] [~frankdu] [~yibo] -- This message was sent by Atlassian Jira (v8.3.4#803005)
