Howmany CPU? How many Cores?

[lpuname]

Can someone identify from the below output howmany cores? and CPU? the server has in RHEL 5.4

you have 2x quad core CPUs.

[Wilfred Chau_1]

cat /proc/cpuinfo |grep "cpu cores"
should return cpu cores : 4

dmesg |grep "CPU: Physical Processor ID"
should return 2 CPUs

Thanks, got it.

Your cpuinfo output pretty much speaks for itself.

Be mindful too as there are certain processors that have HyperThreading enabled so yuor Quad Core CPU will appear as having 8 "cpus".
