Topic: Multiprocessor

[Sven-Roland Simon]

Heya!

Does anybody know if the e-smith 4.0 kernel supports 2 CPU out of the box?

[Orville Carter]

YES! YES! YES! I am running e-smith 4.0 final, and 4.0b7
on two dual PII (not Celerons). It works just great.

No problems encountered.

Here is one of my server  login screens F2:

Red Hat Linux release 6.1 (Cartman)
Kernel 2.2.12-20smp on a 2-processor i686

Here is the e-smith 4.0 final login screen:

e-smith server and gateway release 4.0 (based on Red Hat Linux release 6.1)
Kernel 2.2.16-3smp on a 2-processor i686

I have an IBM Intellistation, dual PII 266 processors.  It is running e-smith 4.0 fine, but I am not getting the info - smp on a 2-processor - at the login.  So, it is probably only running on one processor.

Is there anything that needs to be done during e-smith install to make sure it finds the second processor and runs in SMP mode?

Steven,
  I would guess you are running in single cpu mode. The chip-set on the IBM Intellistation may be the reason. Call IBM, or check their technical website.
IBM provides lots of technical info (after hiding it for many years) for their systems & Linux.
http://hardware.redhat.com/certification/cert-report.php3?mod_company=IBM

On mb's with intel chip-sets installation of Linux in dual-processor mode is quite uneventfull. No tweeking was required on e-smith4.0b7 or 4.0 final.

HEY STEVEN! Well look at at this! From IBM site.

Technical specs:

Intel Pentium II processor based
Primary hard disk controller type: Built In SCSI controller on motherboard
IDE/ATAPI CD-ROM
Matrox Millennium G200 AGP video controller with 8 Meg/SGRAM
Intel 10/100Mbps NIC
PS/2 Mouse

Special notes:
Installer does not properly recognize the motherboard as SMP capable so
therefore system comes up after install in single CPU mode. To enable SMP on
this machine you need to:

Mount install media and change into /mnt/cdrom/RedHat/RPMS and:
rpm -Uvh kernel-smp-2.2.5-15.i386.rpm
From inside the /boot directory run:
mkinitrd /boot/initrd-2.2.5-15smp.img 2.2.5-15smp

The you need to edit lilo.conf and change the following:
change: image=/boot/vmlinuz-2.2.5-15
to : image=/boot/vmlinuz-2.2.5-15smp

and also change: initrd=/boot/initrd-2.2.5-15.img
to : initrd=/boot/initrd-2.2.5-15smp.img

Save the new file and run the lilo command from the prompt. You will need to
re-boot the machine for the changes to take place.

Please note that e-smith 4.0 uses kernel version 2.2.16-3, and you should use the i686 processor variant, not i386 as instructed here.

Oriville and Charlie:

Many thanks.  It works great!
