I am a Linux n00b.
I have a server here with 2 246 opterons in it running Fedora Core 2 64. Is there a way to see if both CPUs are working? In TOP I only see a general number for "CPU(s)", which isn't specific enough....
I checked the kernel startup logfile and it looks like both are identified - sort of - but with a warning message:
Processor #0 15:5 APIC version 16
ACPI: LAPIC (acpi_id[0x02] lapic_id[0x01] enabled)
Processor #1 15:5 APIC version 16
WARNING: NR_CPUS limit of 1 reached. Processor ignored.
ACPI: IOAPIC (id[0x02] address[0xfec00000] gsi_base)
IOAPIC: apic_id 2, version 17, address 0xfec00000, GSI 0-23
ACPI: IOAPIC (id[0x03] address[0xfebff000] gsi_base)
Is the second processor working? How can I check it's performance to be sure?
