how to check whether processor is duel-core

[pnvs]

Hi,
Can anyone please tell me how can I check the number of cores for a processor in HP-UX 11i server.

use
cstm>
map
selall
info
infolog
see the number of cpus and use
#top
to check number of cores

========================================
above is the top output. But how can I see number of cores here. number of cores for a processor means whethre the processor is single core or dual core. If I am rite can you please tell me how to check whether it is Single or dual core processor

if you have itanium do a "machinfo"
or
ioscan -Cprocessor

[pnvs]

Its a PA-RISC system only.

# ioscan -Cprocessor
H/W Path Class Description
===============================
160 processor Processor
162 processor Processor
164 processor Processor
166 processor Processor
#

how can I get whether it is single or dual core with above output

Your "top" listing indicates your system has four CPU cores.

Your "ioscan" listing indicates your system has four physical processors.

4 / 4 = 1, so your processors are all single-core processors.

With dual-core processors, you would get two CPU lines (one for each core) in "top" per each physical processor.

Another way would be to find out the PA-RISC CPU type: if it is not PA-8800 nor PA-8900, it cannot be dual-core.
