i am trying to find out hpw many virtual and physical processors does any linux machine has:
output of /proc/cpuinfo is as below :
using this info how can i figure out how many physical or virtual processor does any linux machine has...is der any better way to find out or any small script
Have a p570 LPAR capped/smt set to 4 physical processors. And currently have virtual processors set to 6 which gives 12 logical processors at AIX. This is for an Oracle9i database server running 4 instances.
What should virtual processors be set to? at least initially?
And how to determine when... (3 Replies)
Hi,
I have two questions here.
I need to find out the number of physical processors the HP-UX operating system is running in. Here i am referring to the physical processors in a system and not the number of cores.
I can get the number of cores using the command 'ioscan -fnkC processor'.... (7 Replies)
Hi all,
I am new to Linux kernel/user space programming having been an assembly programmer in my previous life. I am now using 2.6.x kernel on an embedded CPU that has a few dedicated hardware blocks (including more CPU running just C-code, i.e., no operating system).
There is a single DRAM... (1 Reply)
Hi,
I am on an Solaris machine "SunOS 5.10 Generic_139556-08 i86pc i386 i86pc"..how do i check if I am on an physical or an virtaul server.
Thanks. (6 Replies)
First of all I have performed a Google search and internal search and found several descriptions but nothing I can wrap my head around and feel 100% confident about.
I feel really silly for asking this as I manage a P6 570 with 12 lpars but I have difficulity with Virtual Processors.
I can... (3 Replies)

Hi All,
How can I know whether the server I am connecting to is a virtual or physical one? The server might be having any Unix OS (Linux/Solaris/HP-UX etc.).
Is there any system files / commands which can show these concrete information?
Thanks in advance for the replies.

x86info(1) General Commands Manual x86info(1)NAME
x86info -- display x86 CPU diagnostics
SYNOPSIS
x86info [-a] [-c] [-f] [fB-F] [-m] [-mhz] [-r] [?] [--all] [--cache] [--flags] [--verbose] [--msr] [--mhz] [--registers]
[--help]
DESCRIPTION
This manual page documents x86info, a program which displays a range of information about the CPUs present in an x86 system.
In order to make full use of this program you need to have the CPU ID and MSR device drivers in your kernel with accessable device files
/dev/cpu/<n>/cpuid and /dev/cpu/<n>/msr.
OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
below.
? --help
Show summary of options.
-a--all
Show all information. Equivalent to -c -f -m-r -mhz.
-c--cacheinfo
Show TLB, cache sizes and cache associativity.
-f--flags
Show CPU feature flags.
-m--msr
Dump model specific registers. This feature is currently only supported on a few different processors. Future versions will
include parsing of bits in MSRs for all processors.
-mhz--mhz
Estimate current clock rate.
-mp--mptable
Dump MP table showing CPUs BIOS knows about.
-r--registers
Show register values from all possible cpuid calls.
-s--show-bluesmoke
Show machine check exception information.
-v--verbose
