Yes, because quoting Wikipedia, "The Xeon /ËziËÉn/ is a brand of x86 microprocessors designed, manufactured, and marketed by Intel Corporation, targeted at the non-consumer workstation, server, and embedded system markets."

Comment 2 Sébastien B. 2017-03-26 21:52:41 CEST
Hello Thierry,

Yes, of course, the xeon is a processor dedicated to servers.
But then why the kernel server, is still installed when the "workstation" option is chosen? The desktop kernel is not "compatible" with the Xeon?

Regards,

Sébastien B.
Comment 3 Thierry Vignaud 2017-03-27 10:10:23 CEST
It's not incompatible.
We just auto-select the more adequate kernel flavor.
Kernel-server is built with options targeting servers, not desktop (no preempt, HZ_100, scheduler, ...)

As for the workstation option, if you look at the tooltip, it says "Office programs: wordprocessors (LibreOffice Writer, Kword), spreadsheets (LibreOffice Calc, Kspread), PDF viewers, etc" which is unrelated to kernel choice

You can later install kernel-desktop-latest & remove kernel-server* if you want.
Comment 4 Sébastien B. 2017-03-27 10:34:19 CEST
Hello Thierry,

Thank you for these explanations.
Can one reasonably say, whom the version waiter manages âbetterâ, the multithreading?
Doesn't its employment for a âclassicalâ use disturb of anything, if I understand well?

Regards,

Sébastien B.
