Source: openblas Severity: normal X-Debbugs-Cc: henr...@debian.org Dear Maintainer,
I've found some people complain about Ubuntu/Debian's openblas package via twitter and they rebuild it from source, since it seem that not work as expected with SMP (see http://verifiedby.me/adiary/060 (In Japanese)). I'm not familiar with this issue, but it may be worth to check, IMHO. -- Hideki Yamane <henr...@iijmio-mail.jp>
