So, I'm expecting for you to provide tarballs similar to: $ ls -latr debian/archdefs/s390x/*.bz2 -rw-r--r-- 1 xnox xnox 7191 Feb 5 15:42 debian/archdefs/s390x/IBMz964.tar.bz2 -rw-r--r-- 1 xnox xnox 7835 Feb 5 15:42 debian/archdefs/s390x/IBMz1264.tar.bz2
but for z13, and z14. Also please check the IBMz1264.tar.bz2 tarball if you can or want to change the performance there. If there are any additional patches required to cherrypick from upstream, please point them out. And any compiler flags. For the tuned builds, we can use things like -march=z13 -O3 and so on. if that results in better performance. For bonus points, you can also work on changing the debian/rules to execute the builds multiple times in separate build directories, but it's probably something quicker for me to hack on, once you have the compiler flags / config options / tuning tarballs done. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803077 Title: libatlas not using vector instructions - large performance impact To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1803077/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
