Running Intel's Clear Linux On AMD EPYC Rome? Still Significant Performance Uplift Over Ubuntu

[Michael]

Working full time (or really overtime) at Phoronix.

Would easily make the time for Oktoberfest if that was all, but more pressing is increased ad-block rate / no longer single (freedom) / more expenses to deal with plus a child on the way so no way would be able to make it.

It's been several years since you didn't go there... What happened?

Jealous if you're going to the wiesn.... Sadly I will not be making the journey.

openSUSE Leap loses to Ubuntu on the EPYC 7742 2P as the newest results in - https://openbenchmarking.org/result/...gm=y&obr_rro=y

Thank you! That would be around Oktoberfest time and nearly as much exciting.

Thanks, Michael! Interesting test which I was looking forward to very much, especially the video encoders seem to profit in a big way. Are you planning to add Ubuntu 19.10 / Clear Linux on Intel vs. AMD numbers, too? You were mentioning seeing greater improvements for Intel's own architectures, but it would be great to see some numbers between AMD and Intel on both distributions.

Eventually will do a Clear vs. Ubuntu direct on Xeon Scalable vs. EPYC, but probably not for a number of weeks (probably after 19.10 official) since the Daytona server is my only Rome supported motherboard/platform at the moment and have other EPYC CPUs still to test among other benchmarks, so will probably be a while before I'd have the time to do some interesting comparison.

Phoronix: Running Intel's Clear Linux On AMD EPYC Rome? Still Significant Performance Uplift Over Ubuntu

The current AMD EPYC 7742 2P benchmarking that is happening at Phoronix is an interesting Linux/BSD operating system performance comparison. That's in the works while so far are some Ubuntu and Clear Linux numbers. Yes, Intel's open-source Clear Linux platform does run fine generally on AMD hardware -- including the new AMD "Rome" processors -- and generally does still run damn fast. Here is a look at Clear Linux on this 128 core / 256 thread server with Clear Linux against Ubuntu 19.04 as well as the upcoming Ubuntu 19.10.
