[Bug 1634142] Re: Don't use openblas cmake builds
you used the same skylake cpu on the ubuntu 14.04 version? its probably a good bet to assume the issue was always there instead of it being a regression. openblas is notorious for giving wrong results depending on the hardware used. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634142 Title: Don't use openblas cmake builds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openblas/+bug/1634142/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1634142] Re: Don't use openblas cmake builds
I'll just try to fix the bug itself tomorrow. It should be much easier to trace it down now that I know that I probably need to compile it with the default build target to be able to bisect it (since it worked fine in Ubuntu 14.04). I'll let you know when I find the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634142 Title: Don't use openblas cmake builds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openblas/+bug/1634142/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1634142] Re: Don't use openblas cmake builds
if I had to guess the reason why the package does not work is that the version in 16.04 does not detect skylake cpus and falls back to some other cpu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634142 Title: Don't use openblas cmake builds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openblas/+bug/1634142/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

the cmake change in the github issue does not fix the problem, it just causes you to not use the broken code anymore. can you provide a compile and runnable example for me to try? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634142 Title: Don't use openblas cmake builds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openblas/+bug/1634142/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1634142] Re: Don't use openblas cmake builds
Huh, that's interesting. I encountered this bug while using the system provided version of openblas on Ubuntu 16.04. And I just fixed the bug in openblas itself by adjusting the cmake build files, so I assumed that that was where the bug came from in the openblas version that was provided by Ubuntu as well. I guess not. So there must be another bug in openblas then... I guess I'll have to investigate further. Maybe there's a bug in the standard implementation of trmm.
