Summary: [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 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)
