Since this is really a question in several areas I'll put it here. Now
that the Pentium-D processors are available at reasonable prices and
for quick delivery, can anyone speak to the ACPI issues? The available
boards use the 945 and 955 chipset. Is there any reason to think that
the scheduler would get confused by the CPU, such as thinking it was
HT or some such?
There are only issues with CPUFREQ/speedstep and some ACPI related
things on Intel 955X chipset I have. So I use a ASUS P5WD2-Premium.
The Pentium D will reach me in few days so I only guess and I think the
kernel know how to handle Physical Cores and SMT/HT Processors.
The specs indicate that 64 bit is supported, is there any actualy
Linux support for the Intel 64 bit stuff in gcc and the kernel? One of
the people I work with reports that the distro he runs on his Athlon64
lock solid after reading the boot sector, so obviously this isn't
Athlon compatable.
Yes the 64bit support of the Intel CPUs are well supported, I use a
Intel Pentium 4 640 and 64bit compiled system (Gentoo 2005)
I have no problems everything is working nearly perfect better as my
AMD64 system.
For GCC 3.4.x or 4.0.x you only need the compile switch -march=nocona as
the name of the XEON..but its the same piece of technologie
Okay, unless I can find an Intel-64 build of Fedora I'll have to do it
myself, but now that I know what option to use it's possible. Trust
Intel to have a 64 bit standard which isn't Itanium and isn't ..quite..
AMD compatible.
The price is lower than a dual Xeon setup if you have an application
which needs SMP, and initial power values make it look like a lower
power solution overall.
Cheep and good performance.
Thanks for the pointer!
