Dear Folks:
I have been having a tough time getting a system up that
consists of the supermicro PIIIDME board (840 chipset),
PC 133 ram, and 2 PIII 733 Coppermines. I have the front side bus
set to 133MHz.
Using a 2.2.5-15 kernel, I notice that
the eepro100 onboard nic isn't recognized, and more importantly,
/proc/cpuinfo reports cache size=0.
I wanted to upgrade to 2.3 anyway so that i could use udma66 mode for my ide
drive, so...
Using 2.3.99-pre3, I get the unexpected IO-APIC warning,
the nic is recognized, and /proc/cpuinfo reports correctly
256K cache for each. However the bogomips (which i believe
should roughly equal 733 for each processor) reports 1466 for EACH
processor.
During kernel compiles I noticed the machine was acting quite slow
(compared to my single PII 350 MHz machine running 2.0.36, abit bh6 mobo)
So I ran fftw tests for a rough benchmark:
This is a serial run for a 128x128x128 real fft:
PII 350: ~3 sec, ~75 MFLOPS
PIII 733: ~10 sec ~20 MFLOPS
The result for the PIII machine is the same regardless if
the kernel is a single or dual boot, 2.2.5-15 or 2.3.99-pre3.
Any ideas? Thanks in advance.
